Good morning. I'am using 34970A data aquisition with benchvue software using the RS232 interface. I'am using the test flow to ask the user how many measures he want to do and the interval between measures.
First I ask user the number of times we want make the measures and I put his aswer in variable number
Then I ask the time between measures and I put the answer in variable time
Then I do the following sequence in test flow:
CONF:VOLT:DC (@110,111,112)
ROUT:SCAN (@110,111,112)
TRIG:SOUR TIMER
TRIG:TIM time
TRIG:COUN number
value=READ?
When I run the sequence the data aquisition change the number of scans and the time between them to the one I choose, but I have one timeout error in benchvue software in this line of code "value=READ?"
I try to replace the value=READ? with this:
INIT
value=FETC?
But I have the same timeout error
What I'am doing wrong?
Thank you
Do you have the DAQ app running at the same time you are trying to send/receive SCPI to the instrument from Test Flow? That doesn't work. Try closing the app and use only SCPI, or use only the app, dragging and dropping available functions into Test Flow. You can get at some of the data you might want by using the Data Grid Gadget in the graphics page. It returns a lot of info.
