I got a problem when I used a HP4155A to do some DC sweep measurement.
I set up 2 voltage inputs with sweep-order 1 & 2 ,and 1 voltage input as constant in my ic-cap setups.
But when I started measurement ,the 4155A didn't set 2 SMUs as VAR1/VAR2 and an error code popped up
" ERROR 180 : illegal setup , target module is not installed"
My previous version of ic-cap is 2006B and I never had this problem with the same instrument.
Any suggestion will be appreciated, thank you.
