Continous display refresh while measuring over GPIB

Post by ahartmann » November 8th, 2018, 8:32 am

Hello,

I want to do some measurements with our new Keithley DMM7510.

We have used Keithleys 2002 before, where the commands to read a measurement looked like this:

Code: Select all

  :FUNC 'VOLT:DC'
  :DATA:FRES?
The nice thing was, that between two value reads the display was continously refreshed with the current measurement value.

I'm now stucking a bit with the 7510, because here the display is *only refreshed* when a measurement command is issued. Between two measurements the display stays at the last value.

These are the commands I use:

Code: Select all

  :FUNC 'VOLT:DC'
  :MEAS:VOLT? \"defbuffer1\", READ, SECONDS
What would be the easiest way to achive a continous display refresh?

Best regards,
A. Hartmann

I have solved it with the following code for now:

Code: Select all

:ABORT
:TRIGger:BLOCk:NOTify 1, 1
:TRIGger:BLOCk:MEASure 2, "defbuffer1"
:TRIGger:BLOCk:BRANch:ALWays 3, 1
:INIT
...
:FETCh? "defbuffer1", READ, SECONDS
...
:FETCh? "defbuffer1", READ, SECONDS
Not sure if this is the best way to do such thing? I have to abort the trigger each time I want to change the measurement range, and re-init it again after. Beside that, it seems to work.

Any comments?

Best regards,
A. Hartmann
