Model 6220/6221 Reference Manual Delta, Pulse Delta, and Differential Conductance 5-65
Return to Section 5 topics
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. Details on
the “Arming process” are provided on page 5-56.
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.
The query form for the arm command (SOUR:DCON:ARM?) is used deter-
mine if Differential Conductance is armed. A returned “1” indicates that Differ-
ential Conductance is armed. A “0” indicates that Differential Conductance is
not armed.
If the Model 6221 is already armed for another action (e.g., Delta or Pulse
Delta), the Differential Conductance arm command will “un-arm” the other
action and arm Differential Conductance.
4. During the arming process, the Model 622x acquires the offset voltage
(V-zero) value of the Model 2182/2182A. The Model 622x factors this value
into the calculation for Differential Conductance voltage. See “Voltage offset
compensation,” on page 5-57 for more information.
