Model 6482 Dual-Channel Picoammeter / Voltage Source Reference Manual Section 7: Sweep Operation
Custom sweep commands
Table 7-4 summarizes remote commands used for custom sweep operation. See Section 16,
“Configure list,” for more details on these commands.
Custom sweep programming example
As an example of custom sweep operation, assume a five-point sweep with the following
parameters:
Source and measure channel: Channel 1
Voltage sweep mode: List (custom sweep)
Sweep voltage points: 7 V, 1 V, 3 V, 8 V, 2 V
Source delay: 100 ms
Table 7-5 summarizes the basic remote command sequence for performing the custom sweep
described above.
