Model 6220/6221 Reference Manual Delta, Pulse Delta, and Differential Conductance 5-31
Return to Section 5 topics
1. Use the :NVPResent command to determine if a suitable Model 2182/2182A with the
correct firmware revision is properly connected to the RS-232 port. This query com-
mand can be used for the system configuration shown in
Figure 5-2B on page 5-5.
2. See “Configuration settings,” on page 5-24 for details on these settings.
3. After setting up Delta using the above setup commands, the :ARM command arms
Delta. During the arming process, the Model 622x communicates with the Model
2182/2182A. Details on the “Arming process” are provided on page 5-24.
When armed, Delta will start when the Model 6221 is triggered. Delta can be “un-
armed” by sending the following command: SOURce:SWEep:ABORt.
The query form for the arm command (SOUR:DELT:ARM?) is used determine if Delta
is armed. A returned “1” indicates that Delta is armed. A “0” indicates that Delta is not
armed.
If the Model 6221 is already armed for a another action (e.g., Differential Conductance or
Pulse Delta), the Delta arm command will “un-arm” the other action and arm Delta.
