Labview Error when using Keysight N6705C

Hello,

 

While using the Keysight N6705C I'm getting an error when trying to read back the voltage or power through Labview when passing through the command line :FETC:ARR:POW? (@1) or :FETC:ARR:VOLT? (@1).  It works fine if I want current and pass the command :FETC:ARR:CURR? (@1).  The error I'm getting is:

 

Error -1074001424 occurred at an unidentified location

Possible reason(s):
agn6700 Error Query;
instrument reports:
+303,"There is not a valid acquisition to fetch from"

 

Any help on this matter would be much appreciated. 

Simon

I'm using a N6781A module in the N6705C chassis.

Based on the error, I suspect you can measure voltage or current at a time. Perhaps by default, it measures current, which is why there is no error. When you request a voltage reading, it complains that you have not configured it to measure voltage.

 

Please check the programmer's manual.

Hi Santhosh,

 

Thanks for coming back to me.  I've had another look through the manual and I can't see anything else that I need to do to the SMU in order to read Voltage or Power (see snippet below on Fetch Array Command). In order to read a measurement from the device I am using the Agilent N6700 Series Fetch Array VI, which has the commands built into it.  Also I've tried a separate module (N6762A) within the N6705C and I can get it to measure all three (current, voltage and power).

 

Is there something else I need to do to the N6781A in order to measure the Voltage and Power?

 

Thanks,

 

Simon
