• Isolation between channels SMU 5451

  Hello

  We try to use the exit CH0 + as a floating voltage source. Our instrument is the NOR-SMU-5451.

  It seems that the SMA cable screen is difficult driven ashore by the analog output.

  I can't find in the documentation it is possible to isolate the CHx outputs of Earth.

  Does anyone know if this is possible or not?

  Thanks in advance!

  Hello

  I looked in your query about isolation and it is not something that is possible with the nature of the card being the only complete reference.

  Thanks for posting!

  Kind regards

• measure with the two channels of the virtual bench simultaneously in labview, error 375903

  Hi, I am trying two measurements simultaneously using two channels of analog input of the virtual bench. I chose the channel MSO 1 and 2 for the measures but I get error 375903 returned evewry time say the requested resource is reserved. I'm not under any other software which should use the virtual bench. The error occurs when I'm initializing the session, even before a measurement was made. Can someone tell me how to call each channel so that I don't get this conflict of resource reservation?

  I have included the VI and a screenshot of the error.

  Thank you!

  ASM takes only supported a session unique instrument and your VI uses two. To use both channels, delete the second session MSO and specify channels in the MSO configure Analog Channel.vi

  Here's an example that uses two channels brought:

• Several simultaneous analog output channels

  I use DAQmx-NOR-USB.

  I want to simultaneously generate two analog output signals, i.e. change the two outputs at the same time.

  Simple example:

  

  

  What is happening is that instead of two outputs simultaneous modification, there is 1mS delay:

  

  I want to generate premium output, using two channels, but the delayed response is not acceptable.

  Any suggestions?

  Hi Seth B,.

  Yes, it works!

  A note: to make visible this property, I had to turn on "display all the attributes" in the menu "Select filter" (right click on the node property).

  Thank you.

• Peer to peer between SMU-5451 and SMU-7966R

  Hello

  I would like to connect two devices - SMU-5451(waveform generator) and SMU-7966R(NI FlexRIO) with the P2P streaming. I want to transmit data from FPGA to the generator and I took the example of NOR-FGEN. When I started host-vi, there is an error (see photo).

  

  

  What I am doing wrong?

  Try to set the Active Channel property before the active P2P. Property nodes run from top to bottom, so the Active Channel property must be set before calling the property Enabled of the P2P.

• How to control two channels of simultaneous functions AFG 3200 B generator?

  The AFD 3200 B function generator has two channels. I want to use both channels generations some vague simultaneous sin. I downloaded the labview driver: Tektronix AFG 3000 Series.

  I did three things:

  (1) try to connect to two channels in VI.

  However, all the screws of example do not support the connection of the name of two channels simultaneously.

  (2) run only two signals generating VI with another name for channel at the same time.

  However, a single channel runs after the other.

  Do you have any suggestions?

  Thank you!

  Wu Yue

  Hey Wu,.

  You need two sine waves to be completely synchronized (aka having the same exact phase)?

  If they must be synchronized, then the AFG should on the two output channels at the same time, but you will probably need to configure serial in your program.

  If they do not need to be synchronized, then is there a reason why you would not be able to simply divided between the output signal two BNC? If this isn't an option, then you will probably need to make some kind of trigger to get both channels to start at the same time.

• Error-1074135024 with the sequence mode arbitrary two-channel on SMU-5451

  Hello

  I am trying to use both channels on my SMU-5451 and operate in arbitrary sequence mode.

  In the build step start, I get the error-1074135024:

  Possible reasons:
  Invalid value for the parameter or property.

  Attribute values are not similar in the channels or the specified features. Use a unique channel name or feature name to query the value.

  Unfortunately, I have no idea what parameter or property value causes the error.

  Initially, I tried this with my own VI, and I was able to run each channel individually, but could not get them both to operate simultaneously. As an attempt to troubleshooting Finally, I decided to change the example of arbitrary signals Fgen (Dual Channel) (which worked properly), to see if I could get it to work with arbitrary sequences. I still get the same error. I enclose modified VI, because it is quite a bit simpler than what I'm running.

  I'm under Labview 2012.0.1f3 (32-bit) on a Windows 7 Enterprise (64-bit) operating system.

  Thanks for any help you can offer on how to solve this problem!

  So with the help of your VI I have figured out how to make it work.

  First of all, your VI I noticed that I should wire the specific channel, I just want to niFgen Create VI waveform, but not in VI of arbitrary sequence niFgen set up. For this I devrais either do not fill in the entrance of the channel, either entry "0.1". This gets rid of the original error message that prompted this post.

  Your VI works, but it seems to be designed to write on only one channel at a time. However, I noticed that if I run it with all the waveforms channel 0, change the waveforms to be on channel 1 and click load & sequence, waveforms will be correctly output channels 0 and 1.

  Finally, I worked on that the trick is to create an arbitrary sequence, so use the arbitrary Create Sequence niFgen and niFgen configuration arbitrary sequence screw, single-channel waveforms. Then run the niFgen Clear VI arbitrary memory, then create another arbitrary sequence for the other channel. After that, run the generation VI niFgen undertake. And everything works fine! I don't know why it is important to have clear memory arbitrary VI in the Middle, but it seems to be essential for this to work properly.

  I downloaded my VI relatively simple test that works properly with this arrangement.

  Thank you very much for your help.

• SMU-5451. digital filter Interpolation

  Hello

  I use the SMU-5451 with FPGA SMU-7966R signal generator. They are related to peer-to-peer technology.

  I want to use the digital filter of Interoplation, but there is a place to errors in the property node. Here is a screen of this error.

  What should I do to fix this?

  Looks like the 5451 doesn't have a digital interpolation filter.  There is only a FIR filter on the device.  You can check that this is the case and that the problem is not the use P2P when trying to run a script example that does not use P2P and setting this property.  You should get the same error.

• two channels of analog output to 6259

  I need two analog waves, my output 6259, I have generated the necessary signals but would help with seizure 2 signals simultaneously, how would I go about it?

  The steps are quite the same, just that your 2D table consists of two different tables given 1 d.

• Outbreak of similar PCI-6251 reference edge does not work with two channels?

  I use this card PCI-6251 to acquire data from two channles of entry. I need to use reference similar edge trigger. the trigger for the chan signal 1 and acquire data from chan 1 and 2 chan. However, the error is that this card can't take two channels with similar trigger edge reference. Please check if it's the PCI-6251 limilation. If so, can you suggest any other card can do this work? The normal extent can trigger from one channel and acquire data from many other channels.

• How to find the time between two channels of entry in the data acquisition card or pci 6036

  Hello

  I read a lot-related posts on the simultaneous measurement of two input voltage of similar channels in map data acquisition. I know that the best material is "simultaneous measurments of the Series DAQ cards" but I only pci data acquisition card 6036 and I try to understand what is the time between the reading of the two channels . This period is always constant? (must it rely on a voltage (amplitude, frequency, waveform..). I send the sine wave (s) to the two channels and read the values of V, if they read the same value, the difference should always be zero but I get-0,002 to 0.002 Volt difference (I must find a way to convert it in time). A screenshot of my VI is attached. I wonder how I can accurately measure the time delay between the channel.

  I am open to any suggestion, my final goal to read exactly two channels at the same time ((ou connaître le délai exact donc je peux correspondre les données correspondantes étant donné le temps de retard))

  Hi spinup,

  better you should post your question in the forum of LabVIEW, LabWindows/CVI is used

  Good luck.

• How can USB-6210 I synchronize two channels of ctr

  Hello

  I use LV 8.5.1 and NI USB-6210. A small application I want to generate two different impulses with synchronization but simple starting point. When I configure a task with two channels the second channel configured always starts a ms later. But, if I configure both channels in terms of frequency, they start synchronously.

  My idea is bad in general? The DAQmx part is fixed.

  Thanks in advance

  Hi there, too.

  the release of the finite pulse trains, to two meters for each task. Therefore, your application will be the first impulse using two output counters and then to exit the second impulse using the two counters.

  Like the USB-6210 don't not have outputs DIO correlated, you'll generate two infinite pulse trains (which can be started at the same time throug a trigger of arms) that you explicitly stop before the start of the second pulse (using the DAQmx abort task from a parallel loop), or upgrade your hardware at least a USB-622 x card series and a digital output model... Alternatively, you can use the PCI-6602 counter card and use a counter to Gate two others doing an infinite impulse train uses a relaxing break...

• Find the time to intersampling between two channels AI USB 6251

  Hello

  I want to know how late it is between two-channel sampling of HAVE in a USB-6251 (term mass) used in conjunction with a block of connection SCB - 68 (Labview 8.5, Windows XP).  I realize that there's only an ADC and simultaneous acquisition is not available.  The specs are listed as follows:

  Sampling frequency:

  Maximum: 1.25 MECH. / s single channel;  1,00 multi-channel MECH. / s (aggregate)

  Minimum configuration: no minimum

  Timing accuracy: 50 ppm of sampling frequency

  Temporal resolution: 50 ns

  We know of a way to understand this point other than by experimentation?

  Hello sam2013ni,

  That's all I see for AMC and PUSC. Look in "box Type".
