1. Use the :NVPR? command to determine if a suitable Model 2182/2182A with
the correct firmware revision is properly connected to the RS-232 port. This
query command can be used for the system configuration shown in
Figure
The RS-232 cannot be the selected interface for the Model 6221. If it is, this
query will generate error -221 Settings Conflict.
2. See
tings (:STARt, :STEP, :STOP, :DELTa, :DELay, and :CABort).
3. After setting up Differential Conductance using the above setup commands,
the :ARM command arms Differential Conductance. During the arming pro-
cess, the Model 622x communicates with the Model 2182/2182A.
When armed, Differential Conductance will start when the Model 6221 is trig-
gered. Differential Conductance can be "un-armed" by sending the following
command: SOURce:SWEep:ABORt.
