• Purpose of the "Signal Reset" bulk "Simulate Signal"

  Hello

  What purpose of the "Signal Reset" in the block "Simulate Signal".

  I searched, which once activated, it affects the default value, which is 0 in the output of the block "simulate Signal".

  But it seems that the functionality of the 'reset' Signal is different.

  On figure 1 - Schematic of my installation with pushbutton "Reset Generator" below on the left.

  On Fig. 2 and Fig. 3 - the output of the 'Simulate Signal' block and some derivatives of signal with 'Reset Generator" OFF and WE accordingly.

  As you indicate, in the case WE , the output is not 0.

  Thanks in advance for the clarification

  The reset is used to "reset" the phase of the signal to its default value when the value 'True '.  If you leave the value of "reset" to "false" and you run the Simulator signal in a loop, you will get a contineous waveform, even when your signal Simulator does not generate a whole number of cycle (combination of signal frequency, sampling frequency and number of samples).  If you set the "reset" to "true" the waveform will be interrupted (the stage will be set to its default value in each iteration).

  Here is an example:

  

  "RESET" = FALSE, see chart below:

  

  'RESET' = TRUE, see the chart below:

  

• I have trouble understanding how the calendar for the vi simulate Signal Express. Can anyone help?

  I'm generating a signal to 100,000 samples per second. The frequency is 4 Hz. I then pass the signal through the basic vi trigger detection to find out where the wave crosses 0.5.

  Since the signal is 4 Hz, the waveform should cross 0.5 each 0.25 sec. However, when I created a table of the times that the trigger is activated, it is not 0.25 seconds.

  I don't know if there is a problem with my calculation of the duration of simulation, or if I don't understand how the vi signal simulation works. Thank you very much for your ideas!

  Yes, you made a few mistakes or bad assumptions about who express vi.

  The frequency is 4 Hz samples per second is of 100,000 samples (orders of magnatude) generated too high are 76 (0.76mSecs worth of data).  1% duty cycle so a transition product only once every thousand loops! 1315 or 1316 loops between L - H transition to be more precise

• Simulate signals wired to the DAQ assistant for USB-6009 device

  Hello

  I'm trying to send a signal to the DAQ Assistant Express VI.  I watched the movie "Generating a Signal" on the Web site of NOR (www.ni.com/academic/students/learnlabview/generate.htm) and I have my Signal simulate connected directly on the DAQ Assistant, as shown in this film.  In my case, the DAQ Assistant sends the signal to a device USB-6009.

  However, I received this message:

  Error-200077 occurred to the DAQ Assistant
  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 value: Sample clock
  You select: On-demand

  If I select 'On Demand' in my DAQ assistant and run the vi everything works beautifully.  However, I need my DAQ assistant to be configured to generate a waveform AC continuous, not output a single alternating current rippling.

  What happens here?  I did not have this problem before on other devices of NOR. I am using LABView 2010.

  Please answer.

  Thank you.

• Difference between signal y express sound and Vibration Assistant

  Buenas,

  Cuando instalas el of sound and vibration luego software, tienes back ejecutables: Sound and vibration assistant y signal on purpose. Los abres los back if you lo lo mismo. Mid questions are:

  • What difference between hay?
  
  
  • Da igual use uno u otro
  
  
  • If desinstalo uno los pasa algo back?

  MUCHAS gracias

  Hola, aaramburu,

  in lenguaje andar por casa, Signal Express are el programa matriz y S & VA el are UN modulo what instala encima y reviews una paleta Programación than permite usar funcionalidades specific sonido Análisis y constant. El Signal Express has leaves, apply filters, a configurable software para datos closing, etc. If el S & VA mallards are mallards nuevas funcionalidades enable use tarjetas para señales dinamicas o DSAS that enable leer of tacometros, acelerometros, hacer análisis octavas, etc.. ES como if instalas LabVIEW, are UN lenguaje general Programación y quieres una camara use. Sober el propio LabVIEW has instalar Modulo de Vision para el LabVIEW y is anaden kbes imagen aforementioned funcionalidades.

  No nada desinstales, one extended capabilities. As has using uno u otro, depends on the nature of the application as desarrolles. If going to a Signal Express y seleccionas help > Getting Started with > Getting Started with LabVIEW Signal Express Fiesta el tutorial Básico para el manejo del entorno con guiados exercise. Leads unas cuatro horas. If you want to develop una application of sonido y vibration, using a high port tal y como is muestra in el tutorial help > Getting Started with > Assistant Sound and Vibration.

  I hope this information you follows from utility.

• Timed increase in frequency to "simulate signal.vi.

  Hi all, I am a beginner of absoulte with labview so any help would be greatly appreciated, I want to increase the frequency of a sine wave generated, created using signal.vi simulation, increments together over time.
  In other words, I want the signal.vi to simulate to produce a sinusoidal signal who will say during a period of time increase of 39.5 kHz frequency to 41.5 kHz increments of 0.1 hz.

  Thanks in advance for any help.

  Here's a way to do a basic scan.

  

• Replacement of simulate signal VI with the DAQ assistant

  Hello

  I have a VI fucntioning, where signal comes 2 simulate VI signals and is being recorded.

  I replaced that with the DAQ assistant. I want to know if the wiring is correct and if it will give me the same result as the simulated VI.

  Thank you.

  Hello Andy,

  Thanks for the reply, yes I did that as well, another way to do it is the 'split signal VI' that automatically separates the signal into 2 channels, most of the high sons being Ch 0

• Enter the number of samples to simulate signal vi on front panel

  Hello

  I need to change the number of samples in the simulation of signals vi without manually going through properties. Is there a way to change this pattern-block or front panel?

  Thanks in advance,

  Ragmo

  Yes. You can convert the Express VI to a normal VI by right clicking on it and selecting Open the front panel and then you can change this vI and change the # of samples of a control constant. You can also use the functions non - Express VI as a base generating function.

  attached is a vi that I wrote, but something doesn't seem to not be accurate

  Hi marco,.

  in general, this question boils down to: think the stream!

  Why not use one loop at all?

• Generation of amplitude modulation and frequency modulation

  How to generate AM and FM using simulate block signalling.

  This is not possible with just the simulate signal vi express. You'll need to generate a signal by using this vi and then make your own amplitude and/or frequency of the generated signal modulation.

• Weird behavior with Signal to simulate and loops

  I'm having a weird behavior with Signal to simulate and while loops. Attached a photo of my program. The problem I have is that when I use Stop to stop inside while loop, then use to restart the inner loop, simulate Signal instantly generates a bunch of points of data between when I pressed Stop and Go. By example, if I stop for 5 seconds, wait 5 seconds, then press Go, it will instantly generate data for t = 5 t = 10. What I need is for the generation of signals to stop when I press stop and continue where it left off when I press Go. How can I accomplish this? I have no idea why he exhibits the behavior described in the first place.

  Hi optometry.

  Can you give us a screenshot of the configuration window for the VI express to simulate signal? I was able to reproduce the problem when I used "Simulate the time of acquisition" at times, but the VI's are featured as you described you wanted when I used "run as fast as possible." Have you tried this setting?

• I want to use a Terminal Airport Express to extend network provided by my Fios router/modem without going through another airport base.  Is there a way to do this?  I understand that Apple does not support this, but surely there must be a way to do this.

  Can someone tell me how to set up an Airport Express Terminal to expand Network provided by my Fios router/modem without going through an airport as a base?  I understand that apple does not support this use, but my applecare Advisor said it's possible.  Thank you!

  Unfortunately, your AppleCare Advisor is wrong if he or she has told you that an AirPort Express to extend wireless signal of a Fios router/modem.

  Function of "Extend a wireless network" Apple is an exclusive feature that was designed by Apple engineers to extend the signal from another wireless only router from Apple. Thus, the AirPort Express... or any other router Apple besides... would not be able to extend wireless a Fios network.

  SO... you have the possibility to locate the Airport Express where it is needed... And... Connect it to the Fios router/modem with a permanent, wired Ethernet cable connection, then the AirPort Express can 'extend' in this way.

  Or... If you are ready to add a second AirPort Express, connect the first near Fios modem/router with an Ethernet cable, then the second Airport Express could extend the signal first Express wireless.

  Another way to say the same thing, is that if you want an Apple AirPort router to extend wireless network... then you need two Apple routers to achieve this goal.

• Do I need two devices of Airport express to extend my Comcast router/modem?

  Hi, can someone tell me if I need two devices Airport Express to extend the range of my wifi using a modem/router to Comcast?

  It all depends on "how" you want to extend the scope of the Comcast modem/router.

  IF... you can locate a single AirPort Express Terminal at the remote location where you need more coverage of wireless signal... And... connect the AirPort Express Terminal to the modem/router using a permanent wired Ethernet cable connection. ... THEN... the AirPort Express can be put in place to create a wireless network using the same wireless network name and password as the modem/router.  When you do this, then the modem/router and AirPort Express will act as a 'great' network with many more.

  IF... you can not run the Ethernet cable from the remote AirPort Express back to the modem/router and leave only it connected all the time, then your only other option would be to use two AirPort Express devices.  An express train would be located near the modem/router and connect using a short Ethernet cable. This Express will be set to 'create' a wireless network.

  The second AirPort Express Terminal can then be configured to "extend" a wireless network and wireless to repeat the signal from the first Express... assuming that the second Express is located where it can receive a strong signal first Express wireless.

• A sinusoidal signal sampling

  Hello world

  I'm looking to sample a signal using labview.

  I produced a signal using the block "simulate signal" with controls for amplitude, frequency, etc., and have varified it works.

  I want to taste this signal at regular intervals and store the data. Can someone explain how to sample a signal in labview?

  I watched the white paper next, but he spoke more with the concept of sampling, rather than a tutorial on how to apply it:

  http://www.NI.com/white-paper/3016/en/

  I also looked at what follows, who even once, did not in fact a tutorial:

  http://www.NI.com/Tutorial/3116/en/

  I couldn't find anything in my research. If someone can point me in the direction of a tutorial for sampling it would be much appreciated
