For remote programming, the following commands are used for simple scanning:
ROUTe:SCAN <clist> ' Define scan list*.
TRIGger:COUNt <NRf> ' Specify number of scans (1 to 11000 or
INFinity).
SAMPle:COUNt <NRf> ' Specify number of channels to scan (1 to
11000).
ROUTe:SCAN:LSELect <name> ' Enable (INT) or disable (NONE) scan.
* Any valid switching module channel can be included in the scan list. Make sure to list
them from the lowest numbered channel to the highest. For example, to scan channels 1
through 8 of a Model 7700 installed in slot 1, send the following command to define the
scan list:
ROUTe:SCAN (@101:108)
Exercise 3 — Simple scanning
The scanning example in Table 1-8 assumes a Model 7700 installed in slot 1 of the
