NI-USB-6009

[ichbin]

i have NI USB-6009. could i trigger the Vector network analyzer with it. Network analyzer posses  a TTL input for triggering.

The issue is to give the Network analyzer a clock signal. When the Network anlyzer receives the TTL signal , it should makes ameasurement .

I want to do the task with matlab. I have the instrument control toolbox.

I am new in this field , and it is my first time to work with the usb-6009.

is it possible to achieve this with the USB-6009, or should i buy something else?

thank you for your help

You can generate a TTL compatible pulse with the USB-6009 that might work for the triggering. The Digital I/O is software timed and limited to a few hundred hertz or less. So any pulses will be milliseconds in duration or longer and the timing is not very accurate or precise.

I do not know what your requirements for trigger pulse and clock timing are, but most likely the USB-6009 is inadequate for your needs.

Thank you for your reply!

it is long. do you have an advice?

[johnsold]

My advice is that you provide quantitative, numeric values for your requirements.  Then someone may be able to suggest a suitable device.
