Hello,
I posted this also in the GPIB board, since it concerns labview I thought I'd post here too.
I'm trying to measure and plot drain curves for a JFET. When trying to run it in labview I get the following error message:
Error -1074000000
Instrument reports:
+181,"Illegal setup. Invalid command."
+0,"No error"
I see other people have had this problem, I've reviewed all the previous posts and tried implementing the proposed solutions, to no avail.
Here's my configuration for when trying to run a sweep with Vgs = 0V:
Unit Vname Iname MODE FCTN
SMU1 Vdd Id V VAR1 (drain)
SMU2 Vg Ig COMMON CONST (gate)
SMU3 Vs Is COMMON CONST (source)
I ran NIspy and it told me that the error message is generated after the channels are assigned immediately after configuring SMU3 or SMU4 (SMU3 & SMU4 will both trigger it). If I try to disable SMU3 and configure SMU4 then SMU3 will show that it's disabled on the front panel and SMU4 will be configured and I get the error. After I get the error message, If I go to the front panel I can manually run my sweep using the configurations labview sent to the instrument. So labview seems to be configuring the channels properly but then it halts and gives me the error message.
I've tried configuring/disabling all unused channels and that didn't help. I've also tried leaving the series resistance setting for each SMU as the default and assigning 0V to them, which didn't help either.
Any help or feedback would be greatly appreciated.
