9-12 Stepping and Scanning
SCPI programming - stepping and scanning
Commands to scan are listed in Table 9-1. Notice that many commands from the TRIGger
Subsystem are used for scanning. See Section 7 for details on triggering.
Notes:
1. The <list> parameter is formatted as follows:
<list> = (@X:Y)
Where: X is the Min channel
Y is the Max channel
2. The parameters are explained as follows:
NONE - Disables all operations associated with a scan.
INTernal - Enables an internal scan.
EXTernal - Enables an external scan.
3. Defaults for trigger count:
SYSTem:PRESet sets the count to INF (infinite).
*RST sets the count to 1.
