How to trigger SMU - 6363 AI with the PXI-4142

Hello

SMU-1082

SMU-6363

SMU-4142

LabVIEW 2012 SP1

Hello

I'm trying to trigger action (SMU-6363) analog input with my SMU (SMU-4142). The API OR-DCPower has a VI called VI of Signal to export, that I could use to export the trigger signal in a specific line when 'Complete the event Source' comes up on my EMS.

The problem now is that i ' v tried several lines to transfer the signal to the SMU-6363, but unfortunately I still have an error of DAQmx. Has anyone tried similar before sync? Which internal lines I have to use to get this working? I'm just not producing a moment of tension at the time that the EMS (Single, Point). After SMU has defined the level it must send the trigger for SMU-6363 who would then measure the external signals constantly.

Thanks in advance!

Hello

I solved the problem of routing measure relaxation of SMU with Signal.vi export online PFI0 of SMU-6363 (SMU 3 channel). Then I started every other SMU channels (0:2) with this signal to trigger by using the configuration digital edge measure Trigger.vi (the VI input terminal is PFI0).

I configured the data acquisition sample clock to use the PFI0 as a source of the clock. With this method I am able to measure sinus 2 kHz generated with four channels EMS individually with my DAQ without no phase shift (0.1 degrees) between own EMS measurement and data acquisition.

Hope this helps anyone with the same kind of problem.

Best regards

  • Acquire more than 2047 samples with the PXI-4461 instaled in SMU-1073

    Hi all, I would ask you for help with the buffer limit.

    I intend to buy digitizer PXI-4461 and he instal in SMU-1073 chassis, namely control via MXI Express of Labview installed on a separate computer.

    What I need:

    -to acquire data of a single channel of AI, but at least a sequence of 20 kS by a acquire task, in some situations until 200kS by a task to acquire.

    The question:

    - I can gain more than 2047 samples in a single sequence, like 200kS, with the PXI-4461 installed in SMU-1073?

    Internal buffer of the PXI-4461 is reserved to 2047 samples. So I'm not sure if Labview can download remotely via MXI Express the data in the buffer of the PXI-4461 via MXI Express fast enough without any affection of the sampling program.

    -in the case, this PXI-4461 with SMU-1073 isn't the right combination, what chassis and a controller can do?

    Thanks much for the reply

    It will work for you.

    The on-board buffer 2047-sample is used only as a backup if the flow of data to the PC host (via MXI Express in this case) is not fast enough... that it will be (explained below).  DAQmx transfers data from the buffer of the device to the host PC as fast as he can and, in ideal conditions, should not save the buffer 2047 much at all.

    Let's just say you get 110 MB/s (randomly from a MXI data sheet) flow on your MXI connection.  The 4461 has 2 analog inputs, which will be at 24 bits, we just round 32-bit in case it transfers the data in this way.

    4 bytes/sample (32 bit) x 200,000 s/s x 2 (channels) = 1.6 MB/s, which is well below the 110 MB/s, which will make the MXI link.

    clear as mud?

  • How are we supposed to work with the new motion tweens if there is no editor of motion more?

    How are we supposed to work with the new motion tweens if there is no editor of motion more? Without query editor, we can see what kind of key frames are defined and we cannot set acceleration anywhere. Adobe go us back and use the old motion tweens does want now?

    Hi all

    Flash Pro CC 2014 (v 14.0.0.110) is now available for download through the creative application of cloud.

    We have included a whole new motion editor and several other new features with this release of Flash Pro. The new query editor is completely redesigned, intuitive and easy to use while retaining the basic features and backward compatibility with Flash CS6

    To call the query editor, just double-click on your motion tweens on the timeline (or right click and select "Refine the Motion") and the motion Editor opens in the context of the scenario itself. Double click again to collapse once you have made your adjustments.

    Complete list of the new features of Flash Pro CC 2014 is available at these links:

  • Pulse modulated CW with the PXI-5650 and PXI-6653

    Hello

    I'm trying to generate a signal CW of pulse modulated with the PXI-5650 as source RF and the PXI-6653 as the modulation signal. Basically, I'm trying to generate a simple radar waveform. It seems that it would be possible to use the synchronization Module (6653) to transform the RF output on / off on the signal generator (5650), but I do not know how to route the signals from one to another using LabView.

    Has anyone tried this or something like this before? Can anyone please offer some advice?

    Thank you!

    -John

    Hi John,.

    Reading your post, it seems you want to use your calendar and map of synchronization to the RF output power, in other words, on Off Keying. OOK modulation is a feature built into the 5650. For more information, you can navigate through the NI RF Signal generators Help for devices-RF signal generators > NOR -> NOR 5650/5651/5652 overview-> Modes of Modulation and simply click on the Modulation Modes.

    An example of this is found in the example Finder OR by navigating to the help-> find the examples in LabVIEW and then navigate in the Finder to example NOR material input and output-> Modular Instruments-> NI - RFSG-> signals-> RFSG 565 x Digital Modulation.vi.

  • OR DC Soft Front Panel, minorbug, small bug with the PXI-4110

    Hello

    The NI DC Soft Front Panel V14.0, with the PXI-4110, scrolling to negative tension, works as expected to-10V, but then returns to 0. If we change from - 1V procedure, it goes...-8-9,-10, -1, -2... instead of-8-9,-10, -11, -12...

    Thanks a lot for your help.

    Hi Akush, when you install 7 - zip, make itself the default application to open .zip and .rar files. So if you double click on the .rar file, it should open in 7 - zip. If you prefer to decompress immediately, right click the file and look for new 7 - zip items in the menu. I can't think of a way to do this automatically, however.
