Setup and arm commands
Commands sent from the PC to the Model 622x to set up and arm Differential
Conductance are listed in Table 5 -3 . Additional information for each command are
provided in notes that follow the table.
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 5-2B.
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 “Configuration settings,” on page 5-55 for more information on these set-
tings (:STARt, :STEP, :STOP, :DELTa, :DELay, and :CABort).
