User defined signal

[kajo97]

Hi, I am stuck with a problem. I need to find out how to send data as a user defined signal on a Agilent
U2300A Series USB Modular Multifunction Data Acquisition Devices.

Thank you in advance.

Search the NI ID Net for third party instrument drivers: http://www.ni.com/downloads/instrument-drivers/

This one might be the one you're looking for, but have a look for your specific model: http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_model_id=15798

When you download the drivers, you'll want to extract the zipped folder in C:\Program Files\National Instruments\LabVIEW ###\user.lib

Many thanks for your reply. It works, but can I ask if it is possible. How can I apply the same process, but I have to have loaded the arbitrary waveform from the CSV file, like on the pic. I'm trying to figure it, but I'm stucked with it.

Thank you in advance.

I guess you have the right idea here.  I would recommend checking the format of the date you are sending to the device (by using a probe on the wire).

You might want to use the Read Delimited Spreadsheet file to read data from the CSV file.

Also, I would check the termination character, I noticed you didn't have one there - do you need one?

Here is my small program. I don' know if my SCPI commands sequence is wrong, cause it works with a non user defined signal. When a change the user defined signal to SIN or TRI the it works. My proglem is, that i do not know how correctly use this command DATA[:USER]. Thank you in advance.
