• Several analog inputs with different configuration differential/CSR

  Hello

  Can anyone tell how to measure two analog inputs with different configurations using a USB-6009?
  I am aware of the syntax for create virtual channels for the channels DAQmx create virtual so I created two strings using Dev3 / ai0:1 but I would like the first string of the CSR and the second to be differential.
  So far I have found no way to specify the configuration of the separate channels.

  Any ideas much appreciated!

• Analog input for NI EVS-1463RT loging

  Hello
  Im trying to connect an audio input OR EVS - 1463 RT (LabVIEW RT App). I thought that the audio input behave as "analog input" for example DAQmx Device.

  Is there a driver to control the acquisition on audio input NI EVS-1463RT? I need only to connect the sound signal and save it for the next treatment.

  Thanks for the replies

  In LVRT there is absolutely no way to use these audio jacks. I think they're working on the Windows version however.

• iMac with Thunderbolt - how to get the old analog inputs

  I hang up my old Mac Pro in 2005.  I used it to record video cameras and mainly music best of my plate rotating and stereo system - vinyl and CD disks via s-video and RCA cables and Firewire for Mac Pro.

  The iMac 27 "new is primary Thunderbolt and I can't find a Thunderbolt conversion box so I can enter my analog input RCA and S-video signals.  No indication on the Thunderbolt converters 'both ways' I can't exit analog in the iMAC, then the iMac as well?

  They certainly run Final Cut Pro X on the iMAC, then how people get their old media and music in the machine?

  I'm about to talk to the local Apple store, but the chances of finding someone who knows what they are talking about with the iMac, Thunderbolt and analog input is going to be a stretch.

• 550-215na Pavilion: no sound from the rear audio input jack

  Hello

  I recently bought a new PC and I immediately ran into an audio problem that I can't understand. I get no sound at all from the rear audio input jack. I'm getting sound before making, and the plug rear mic works. When I plug something into the rear socket, a message appears grateful that there is something. When I checked the sound settings while it is plugged into the rear outlet, the equalizer is moving, which indicates that he gets his. But nothing comes out when I plug headphones or speakers in. I can exclude a fault with the speakers and the headphones, because they work very well to come forward. All the drivers are up to date.

  Any help would be greatly appreciated!

  Hi there @PrimoFigs,

  I hope you find your experience of positive Support Forum! It's a good place to find the help you need, other users, the HP experts and other members of the support staff. I understand that you get no sound from your speakers when connected to the rear audio ports. I'm happy to give you a helping hand with this.

  Have you tried to connect another device to this port, whether it of a different set of speakers or earphones, headphones just to test if one of them works?

  What it is connected to the front port at the same time? If so, then disconnect this device and try again the rear port and let me know if there is a change.

  Also try this: desktop HP-no sound on speakers (Windows 8).

  Please let me know if any of the work of tip for you suggestions and if we don't solve your problem, please mark this message as a solution. Bravo would be appreciated as well.

• EliteBook 840 G2: Component line software plug-in to an input jack audio combo?

  my laptop has an input jack audio combo and I want to use my laptop's built-in speakers to listen to any devices playing external music (like the smartphone, player or turntables, cassette etc.)

  the built-in speakers are functioning normally when anything connected to this plug. (the built-in microphone works normally and the built-in speakers are functioning normally.)

  There is no problem as well when I connect headphones combo of my mobile phone + microphone with connector PLUG device (line 3/4 pin 3.5 mm male) to this Jack, and I can use in videoconferencing and. This means that when I connect it to taking combo on my laptop, the audio output only made this listener combo + micro, no built-in speakers, and audio input only comes from this listener combo + mic peripheral, not from the built-in microphone.

  But, when I connect an external audio source to this Jack with a TRS connector (line 2/3 pin 3.5 mm male), it is still detected by the Control Panel audio DTS PHYSICALLY (there is a message in the lower right of the task bar button) but not detected by the recording of the Panel tab

  Hello

  You cannot use it in the form online and in many cases, it does support a microphone stand alone, you can use headsets whose microphone + headphones.

  Kind regards.

• Genesis 4 Apple Tv doesn't have an optical Audio input jack.

  I just replaced my generation 3 Apple Tv with a generation 4 Apple Tv.

  The Genesis 3 has an optical Audio input jack that I used to connect my Bose system.

  The Genesis 4 doesn't have it.  Now I can't audio through my Bose system.

  Any suggestions?

  Use something different? I have read there are some cards, but you are right, that the v4 of the Apple TV doesn't have an optical port.

• Problem with analog inputs on sbrio 9627

  Hey guys!

  I have a problem in my Single Board RIO 9627.
  I use 4 differential analog inputs (AI0, AI1, AI2 and AI3).
  What happens is that when I place a sensor or even a button on one of the entries and nothing on the other inputs, it affects all other inputs, increase in the level of each input voltage.
  Can someone tell me how to solve this problem in the hardware or software?

  Thank you!

  Multiplexed inputs must have a low impedance! If you have pictures of ghosts.

  Attach entries open to GND (or do not read )

  If you want to read switches or buttons use a pull upwards or downwards the resistance.

• Analog input and output using 5640r

  Hello world

  I'm Christine, I'm implementing OFDM on fpga using 5640r.

  The code that I have, which is good in the simulation using labview and also using 'nor 5640r treatment only' but I want to implement in "analog input and exit vi" so that I can send and receive on the same card 5640r

  After so much attention in this regard, I am still unable to find the issue, then the soultion to this question. something that I am able to understand that maybe there would be some questions (ADC and DAC) clocks the clock setting

  I have attatched that vi. Please take a look at

• Input signal is set to +/-0 .5V when it is connected to an analog input

  Hello

  I have a difficulty connect an analog source to the analog inputs of my acquisition of data (USB-6215). The analog signal is output operational amplifier through a 10 k resistor. I wore the signal out of the amplifiers is 10V peak, I then move the probe across the 10 k (the analog input terminal) and the signal is clipped to +/-0 .5V. If I reduce the amplitude of the signals of source less than 0, 5V Ridge there is no clipping.

  Maybe the analog input range the value +/-0 .5V which is causing this as a form of protection? I don't have a LabView to try to change the input range as I do just the wiring.

  Analog source is connected to him HAVE 0 and the ground of the analog source is connected to the GND AI.

  Thanks in advance.

  Joel-

  Have you tried to read the data through the data acquisition device?  If that's what you try to do, I'm curious about what we read.

  If you have measurement and Automation Explorer, go ahead and open a Panel to test for the unit and see what are your tensions.

  Let us know how it goes.

• 6008 analog input - invalid values

  Hello

  Does anyone know how the analog input voltage 6008 invalid handles?  Specifically, what happens if the circumstantial channel is configured for a 0 - 10 range v and a voltage negaitve, (-19.0) volts is placed on the analog input?

  I use the library, C/C++, OR-DAQMx library.  The call that I use to set up the port of AtoD is:

  DAQmxErrChk (DAQmxCreateAIVoltageChan (taskHandle, AINPSTR, "", DAQmx_Val_Diff, 0,0, (float64) s_dMaxAnalogInputVoltage, DAQmx_Val_Volts, ""));

  where: s_dMaxAnalogInputVoltage = 10.0;

  and

  DAQmxReadAnalogF64 (taskHandle, 1, 1.0, DAQmx_Val_GroupByChannel, values, 5, & not read, NULL);

  to read the circumstantial.

  What will happen if any illegal input voltage is applied.  I know that everything is a wide range, so I don't talk about something like -60 to + 60 volts.

  Thank you

  -Neil shore

  These specifications are in the datasheet of the product - link to it in the product specifications of the page tab.

  And no, there is no error generated when the input is out of reach.  Scaling the proper entry so that this doesn't happen. or if this is the case, your software recognizes that is higher than expected.

• read the multiple analog inputs at the same time

  Hi all

  I use USB-6001 and want to develop an application to multiple tasks in C++. I try to read several analog inputs at the same time, but got some errors. To put it simply, I copy one of the sample code to read in analog data in a channel, and then turn it into function. Then I call this function to thread with the names of different poles (for example Dev1/ai0, Dev1/ai1) and I come across this error:

  "The specified source is reserved. The operation can not be specified such complete"code of State-50103

  I have search the forums, this may be because I use the hardware timing in this function, and this material timing cannot be used simultaneously by multiple tasks. I may have to put all the lines, I want to read in a single task (such as Dev1 / ai0:1). This way I can read two lines at the same time. However, when I try this, I encounter another error:

  Status code "buffer is too small to contain the data read" - 200299

  So here is my question, what should I do if I don't want to read the multiple analog inputs at the same time? Is the thing that hard time cannot be used by several true task? If I have to read several lines to a single task, how to set the settings?

  
  

• How to compare analog input signals?

  Hi all

  I use PCIe6363 DAQ to collect the analog input signals. Mode of input signal is continuous and single channel several example. The sampling frequency is 2 ms/s, number of sample 100KS or less. This means DAQ 100KS of collect and draw a line/curve. I want to compare the two curves. The problem is DAQ continuously collects data and plot also continuously. Would you please is it possible to compare the curves of this operation continuous operation. The main goal is to justify whether or not the signal of incomeing maintain consistency.

  Thank you very much

  You can store a waveform in a shift register.  Then you have in memory compared to the new waveform.

• Several analog inputs seem to change any of the other (details DAQ: 2120 BNC and 6062E)

  I use the BNC 2120 DAQ board connected to the data acquisition card 6062E to record two analog inputs. An entry is connected to ai0 and the other at ai1. Example vi: "Acq & graph int clk tension" has been used to measure the two entries with the value read NChan NSamp vi (channels being dev2 / ai0:1). The output is the top graph in the image. However, this seemed a bit strange to me that one of them should be modulating with a different frequency. When I record both entered individually (two in low pictures) they are indeed different since the entries shown in the top graph.

  

  Why this would be the case, and how can I overcome this to measure the real signals?

  Thank you!

  The E series card takes the samples as soon as possible. Thus, for example,.
  If you have 16 analog input channels but you only read of
  channel 0 and 1, the map will show the channels 0 and 1 right
  After and then wait 14 'ticks '. What's that little run-in
  the origin of the afterglow.
  I think you can get the card to wait a certain
  number of ticks with a property node. I have attached a screenshot. You
  can find the property node in the palette of functions >
  Measurement of e/s > NOR-DAQmx > node Timing. Expand it
  Property node so there's two entrances. The properties are in
  Left click on the node and going more > converted >
  Its properties delay units and sampling clock delay and delay that
  you want.

  If the phase is important so the above is not the best
  the option because it causes a delay in phase. So, if you need true simultaneous
  sampling, then you will need different hardware. The S series is everything
  simultaneous sampling.

  Or, rather than the Delay property and delay units, try the Rate property
  find more > converted > rate.

  If this is not
  work either, you can move the second signal source to, say, AI8 and
  Connect everyone to the ground. Readings for these, but just do not take into account
  the data. In this way the ADC will sag to the ground at the time where that can happen
  the second string in the way so that you should not see this frequency

• Problem with a precision of analog input on PCI-6111

  Hello

  I'm reading an analogue signal which varies from 0-11 V using a card of acquisition data PCI-6111.  The signal comes from a Tube set (PMT) which is part of a microscope configuration, so it is very important that the resolution of the analog input signal be as wide as possible generate quality images.  According to the data sheet for the PCI-6111, the analog input resolution is 12 bits, which should correspond to a sensitivity of ~2.686 mV for my voltage range.

  To test this, I set up a task to analog input with a 0-11 V voltage range to read samples of an analog output, which I wrote a simple waveform.  Since the 16-bit analog output resolution that I assumed that it would not limit the accuracy of this measurement.  I have attached the VI I used for this measurement below.  The analog input data are saved not truncated in a text file.

  Analyzing these data, I found that the real input sensitivity is ~9.766 mV, corresponding to levels of voltage exactly 1126,4 and ~ 10 bits.

  Is there a reason why the resolution of analog input is much lower that it is indicated on the card?  What are some of the ways I could improve the sensitivity of this measure?

  Best,

  Keith
