Keithley 2000 and 7002 with trigger link

[Morgue]

Hello!

I am writing an application for the 2000 DMM and a 7002 switch system. The instruments are set up with trigger link. What I want to do is simply to load a scan list to the 7002, scan and read back the results from the 2000. Here is what I have so far in terms of SCPI (I have looked at the Keithley LV drivers but I think they complicate stuff + there are no high level functions for trigger link setup included):

DMM *RST

SW *RST
SW Open

SW Scan (@2!1:2!40)
SW :TRIGger:SOURce TLINk
SW :TRIGger:TCONfigure:PROTocol ASYNchronous
SW :TRIGger:COUNt 40
SW :ARM:LAYer2:COUNt 1

DMM :TRIGger:COUNt 40
DMM :TRIGger:SOURce EXTernal
DMM :INIT:CONT ON

SW :ARM:LAY1:SOUR IMM;COUN 1
SW :ARM:LAY2:SOUR IMM
SW :INIT

DMM :TRACE:DATA?
   
Please advise,

Stefan

I should add that what happens after executing my code up until the second last row...is nothing.

The scan begins as expected if I press the STEP button on the 7002 front panel (after going LOCAL) which suggests I am doing something wrong with the initiation of the trigger layer. Perhaps.

Solved! The only thing needed was to command the swithch

:TRIGger:IMMediate

after the :INITiate

hi morgue!

I am doing a program like your, but with Keitlehy 2001.

To make the syncronization you wrote just these lines? I am doig this in labview, with the programs found in the drivers given by keithley but is not working properly. When I put the triger link, it scans and show just the first measure.

Do you still have this programm?

thank you
