Hi, my lab has one NI 1073Q Chassis containing SMU 4141 and 4132.
Recently, we are going to add two voltages to FET device: Vgs is (-100V to 100V) from SMU 4132 and Vds (-10V to 10V) from CH0 of SMU 4141.
The problem is: is it OK to connect the LOs from both 4132 and 4141 to the Chassis Ground?

Any reason you would want to tie them to Chassis?
Of course, you can connect both the LOs of the SMUs together on your device board or the connection.
