• test limit digital multiple

  Hi all

  I have a question about multiple digital limit test.

  My data source is a table tab1 [].

  I need to compare each item of tab1 [] with the element that is associated with another table tab2 [].

  In other words, I would like to check the weather tab1 [i] > tab2 [i] (for i = 0; i > 32; i ++)

  Simple problem isn't? However, I can't find any effective solution to specify my expression "Low Limit"! ^^

  To be more precise, I would say I want to create different expressions "Low Limit" 32 (Low Limit A = tab2 [0] , low limit B = tab2 [1], etc. would be a bad solution). I would like to create an expression that would be able to handle all of the comparisons. Is this possible?

  Thank you very much for any help!

  I think that the best thing to do in this case would be to use a regular step numerical limit with the parameters of the activated loop. Your data source would be set to something like:

  Locals.tab1 [RunState.LoopIndex]

  And the type of comparison would be GT with the low limit:

  Locals.tab2 [RunState.LoopIndex]

  You can set the parameters of the loop on "Fixed number of loops" stage with 32, or you can use the custom loop type based on a fixed number of loops with the expression of loop while the value to something like:

  RunState.LoopIndex<>

  Hope this helps,

  I want to connect a led of color rojo como indicator signal pero nor even obtengo una Señal.

  The favor su apoyo pido

  Saludos cordial

  Buenos Dias, Rafael,

  Me designed that are MAX a self-test, esto hiciste en el para poder saber if you componente esta in buen estado. If you llegara a dar como resultado as no lo pasa ahi tendriamos problemas.

  Sin embargo, no creo as you sea este caso, todas maneras No debes pasar por el alto hacer esta prueba.

  MAS especificamente sober lo as our questions, esta tarjeta tiene relevadores estado solido, por lo as the conexion no can be directa.

  In estos links to habla a sober poquito como hacer las conexiones para una Señal TTL handle, not con the cual no tendrias problemas para poder encender UN LED.

• Multiple TestStand limited digital test next tep

  I am a multiple test limits digital step stype of coding and I have a fundamental question/problem that I don't see a simple solution to.  If I'm measuring and comparing 4 differnet settings, I have 4 different steps to guide out of depending on the result.  How you code this optimal in Teststand?

  It is excellent.  Thank you very much.

• To a result NULL of Labview TestStand to a type of digital test limit.

  Hello:

  I am looking for a way to pass a null value as a result in a limit test multiple digital test type.  My tests are written in Labview.

  The tests now pass a value of '-' 999 to TestStand to signify that this measure has not been made, but this requires additional processing and code in our data analysis tools.  Passing a value zero would simplify the tool and reduce the workload.

  Thank you

  Mike

  You can switch NaN instead.  At least, I think you can.  TestStand supports NaN, but I never spent through Labview adapter, so I'm not 100% sure if it will work.  NaN is treated in tests limits labview as follows (hat tip to James Grey here):

  (NAN > x) == false
  (NAN == x) == false
  (NAN< x)="=">
  (NAN == NAN) == true

  I don't know how it would be dealt with when writing a good database.  I guess it depends on the data base and values of what digital special supports.  A quick search shows that NAN (not sure if he would lift an error or that) does not support Sybase, MySQL stores NAN as NULL in numeric fields, SQLite stores NAN as a special string code, Access stores in the form of NAN.

  So you should always write a step for translate NAN for NULL values, but I think it would be easier to write and maintain than an arbitrary number.

• Output digital USB 6008 when connected does not

  Hi, I have an external circuit and I want to control it using materials DAQ 6008 / using LabView, I tested the digital port work (giving me 5V) but once I connect it to my circuit (PIC16f887) pin his Gimme 0V, I do not know why

  because the NOR-6008 has an exit open collecor must connect a pull up resistor to + 5V.

  

• Digital input and output problem

  Hello:

  I do a test for digital i/o:
  for a table of the digital signal to an output of data acquisition in the digital input to detect the output signal.
  (bascially, it's like a loop that goes outside the material)

  It's pretty simple, as shown in the attached fichier_1.
  It works well.
  The manual light switch controls, which means that inputs and outputs are ok.

  Then I went on the low level DAQ for better speed, as in attached fichier_2.
  But it does not work. Especially when I pressed stop to abort the loop, an error has occurred:

  To speed up, I went to the low-level data acquisition as the fichier_2 attached.
  But it does not work. Espeically when I press the "stop"button to exit the loop, the error occurs.

  Possible reasons:

  Requested value is not supported for this property value.
  The value of the property may be invalid because it is in conflict with another property.

  Property: SampTimingType
  Asked the valuelarge clock
  You can select: on request

  I don't understand why the sampling time has a conflict here.
  (It is probably just something very simple in data acquisition, but I checked a few examples and did not find a clue).
  Hope someone can give me a suggestion.

  Ultimately, my goal is to make the attached file_3.
  In this one, I generate a digital output, and then lead to the entrance.
  Then I can take it as a signal to trigger my other task.

  Note:

  I use a similar conti signal to control one of my camera.
  I need to sync it with my another task.
  So I think to generate a digital output (which share the same clock as the signal similar to the data acquisition device), then put it in one of the digital input.
  By detecting this digital input, I can trigger my task and synchronize with this signal similar.
  My camera's USB-6211.
  I am aware of the latency of USB, but once the value is a constant value, then the synchronization is always good for me.
  Actually, I was using an analogue at the entrance of the to do it before, it may work, but the synchronization error is too big for me.
  I need to do some calculations/judgment for this analog value, which makes the time difference varies.
  So I'm trying digital entry now and I hope that the digital input can trigger my task with a stable latency.

  Thank you very much

  Have you looked at the specs? It clearly states that the digital I/o is a programmed software. You have not any hardware clock at all. The best rate that you could possibly achieve is around 1 kHz and which would have a considerable jitter the nature of non-determimistic of windows.

• DAQmx write (digital) works in mode "highlight execution", and not in normal mode

  Hello!

  I would like to create a simple vi (it will work as a Subvi watchdog in a project) to send TTL 5V 0V 3 seconds 3 seconds, by performing an iteration in a loop.

  Use a card PCI-6703 to that effect (beside that I use for the generation of analog static waveform on several stations). I also have a DAQ USB6212 card, and I have test my digital output with this USB card digital input via MAX.

  The strange thing is that when I run my code in mode "highlight execution", I get what I want: 5V 3 seconds, 3 seconds, 0V, iteration.

  When I try to start it in 'normal' mode, I only see the 5V constantly from the output through my digital entry in MAX.

  I know I'm doing something wrong, but no idea what...

  Please find attached the vi simple.

  Thanks in advance!

  Kind regards

  Your overall loop time is 3 seconds (3000 MS of waiting).  You have a 3 second delay between writing the real and write the value false.  But as soon as the false is written, the loop reminds immediately (the second set of 3 waiting operates in parallel to the writing-Delay-Write sequence) so the real gets drafted immediately after the fake.  It will be just a blip.  So that if you run in the execution of climax, the code goes pretty slowly so that you see the Boolean value False as LabVIEW takes his time data flowing drawing wires.

  Put a delay function after your DAQmx write wrong, as well.

• Alienware m17x R4 Digital Out question

  For a long time, I had a problem with my digital output. I can't really 5.1 audio on my computer even when it is plugged into my audio receiver. I have the Sound Blaster Recon 3Di, but there is no option to set the DTS or the sound of doby. If I go to playback devices and click on properties, I test Dolby digital, and I hear all the speakers work. But the sound-blaster software does not work unless I chose to play stereo sound to the digital way. Can I get the front speakers. 5.1 selected with the sound-blaster software give me only the front speakers. It seems that it is only play stereo no matter what camera I have set for the sound, speakers, digital output or my TV.

  I guess that the sound blaster software has no opportunity to tell pilots to use 5.1 instead of stereo. I use Windows 8.1, but I think that it does the same thing, even when I was with Windows 7. In the channel mixer adjustment menu, it shows only 2 channels for the digital output. I wonder if it's a driver issue or a setting in windows that I need to fix. Any ideas?

  Hello. This section of the forum deals mainly with computers Dell laptops with Realtek, IDT and Conexant audio. Only the Alienwares have Creative sound cards, so I don't know much about what you can do with this hardware/software. There is a section called the Alienware Club. If you post here tell them that you posted already here while they just refer.

  Having said that, here's what I 'think' goes with your sound on what I know about the other Dell laptops. The Quick Installation Guide for your model of watch you have 3 Sockets audio, all capable of output to speakers when it is configured to do this. In other words, the mic socket can become an extra speaker output jack. This means that you should have the ability to setup your laptop for a 5.1 speaker system surround and attaching the cables of 3 speaker (of an analog 5.1 amplified speaker system) for the 3 Sockets (front, rear, Center / LF). You must have a source that has a surround sound, like a dvd movie. I don't know if your creation can simulate surround sound when the source itself is only stereo.

  On the s/pdif connection. S/pdif is a 2 channel protocol. When there are additional channels from a source that contains a sound surround, they are coded into the main stereo signal. The receiving device must be capable of decoding the surround channels and transmitting them to the speakers.

  When you use 3 analog computer Sockets, the computer performs the decoding, but when you use the s/pdif output computer does not because he would not be able to get additional channels decoded, as s/pdif carries only 2 channels. To the best of my knowledge, except for the selection of s/pdif to be the default playback device, there is no other software needed adjustment. Surround channels (if present in the source) will be included in the primary s/pdif signal and after that it is at the receiver. And if the source material does not contain the surround channels, then this is the receiving device to have the ability to simulate the if you want to hear through the other loudspeakers.

• How to reset the sensor of fingerprint on Portege R700-174?

  Hello!

  my "problem":

  on my portege (r700-174), I run a win7 (which was preinstalled on your laptop), a victory for 8.1. and for some is true the technical preview of win10

  all systems are protected by password and fingerprints.

  also the win10-test system (for test prints digital-utility in win10)

  now, I deleted an old generation of win10 and do a new install with the latest version

  Unfortunately I forgort to cancel the registration of the fingerprint I had entered with this old win10 - so now this finger cannot be used
  to be entered for the new win10 (or any other system)

  My question

  is it possible to reset it completely (clear all the fingerprints for all systems) the fingerprintscanner out of one of my systems running or to cancel the registration of the
  Fingerprints for this system, which does not exist anymore on my portege?

  Thanks for the tips

  Kurt

  The fingerprints are stored on the fingerprint sensor and you will need to follow the instructions of this Toshiba document to remove your scans of fingerprints.
  http://www.MyToshiba.com.au/support/items/FAQ/386

  In the case that this procedure does not work, only the Toshiba certified maintainer would be able to erase fingerprints users digital related privacy information on the fingerprint sensor fingerprint flash.

• Recommend products OR for my application (controlling several instruments at the same time)

  I'm new to Labview, currently only using the trial version.      There is money in my budget to buy control software, but I need to qualify my needs.

  What I try to do is to control several pieces of equipment to test as a single system, which allows me to perform automated on conventional measures

  and digital two way radios.

  Here is a list of the material I want to control:

  First of all, my controller is a & Rohde Schwarz 3 PSL.   Fully GPIB active and ready.  It is the PC control software will reside on.

  Equipment:

  Spectrum analyser Rohde & Schwarz FSEA 30 with modulation analysis package digital option B7

  FSEA 30 second, same configuration

  R & S AMIQ4 I / modulation generator Q (files of the software residing on the PSL3)

  Generator of analog signals from R & S SMY 02

  Agilent E4431B analog-to-digital signal generator

  Agilent E4406A spectrum analyzer/digital radio test set

  E4418B Agilent RF wattmeter with sensor

  General Dynamics R2670B service monitor

  A typical application will be a test of classical radio on VHF or UHF analog channel.

  The idea is to enter pass and receive frequencies through Labview or any software is best suited for the job, as well as modulation parameters.

  and have the following things occur: assume usage of 150,000 MHz with a FM frequency modulated 1 kHz sounds modulated to the deviation of 2.5 KHz

  in total, with your 127,3 Hz subaudible to a gap of 300 Hz

  Test phase of receiver: send commands to control of instrument of Agilent E4431B signal generator.   Level set to-60 dBm.  Set to 150,000 MHz frequency.  Set

  Audio 1 to 1 KHz and audio tone 2 to 127,3 Hz at a level of 8 pecent of your 1.  SD total do not exceed 2.5 KHz.      Inject the test signal into port RX

  on the radio.

  The value R2670B SINAD function, related to the radio via the audio output port.

  Signal level to ramp down to the SINAD falls to 12 dB.

  Increase the level of the signal to the attenuation of 20dB.   Measure the audio distortion.

  Testing of transmitter: using the attenuators appropriate necessary on the analyzers of spectrum, and/or using a switched network of wiring.

  place radio to transmit using above specifications frequency and modulation.    Analyzers to receive on the frequency designated value

  and measure the transmitter specifications, including nonessential radiation measurement and harmonics.    Measure actual output power

  Via E4418B-power meter.

  I use two monitors to perform multiple tests in a same transmission. One is optimized for spectral purity tests while

  the other analysis of modulation characteristics.    Frequency, duration and RBW are defined according to the needs.

  When you test a digital radio, the signal chain is slightly different.  The AMIQ I / Q modulation generator s I / Q outputs are sent to the

  I / Q inputs on the Agilent generator, the power is on to accept external I / entered Q and the FSEA Spectrum Analyzer (an a)

  the) is passed to a preset that implements all relevant digital parameters so that it can be used to directly evaluate the digital transmissions.

  It is not a very developed in the planning system, but I do not know now whether Labview is everything I need or if I'll need to Teststand or another

  software packages.

  I'll probably want to ask for some advice on how to get this set up, eventually.

  LabVIEW is more than capable of this task. That's what it was designed to do. Use the help > find the instrument Drivers to find and install the drivers that you can use to control and read.

  TestStand generally requires the use of a programming language. It runs the tests that you write and provides functionality built for the production of record and report database then you would need to write these modules yourself with LabVIEW fair and some add on box to tools. For a single test configuration, it is perhaps an exaggeration, but it is interesting to watch as an addition.

• Step.Limits Set with ActiveX

  Hello

  I work on the development of a VI to create a TestStand sequence based on a set of inputs to an excel file.

  With LabVIEW, I was able to create a new file of sequence and insert a test "LabVIEW digital limit" in the sequence (VI attached for adding new digital step). I don't know how to take this additional numerical limits and put 'Step.Limits.Low' & 'Step.Limits.High '.

  Grateful if someone can let me know if/how this is possible.

  Thank you best regards &,.

  Don1

  PS: Please advise if I should have posted this on the set of LabVIEW.

  With the help of the reference step change for a reference of PropertyObject (Step.AsPropertyObject), then you can change the default values using the PropertyObject.SetValNumber using the search string for "Limits.Low" and "Limits.High".
