Model 2750 Multimeter/Switch System User’s Manual Getting Started 1-33
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 main-
frame. The scan will use default settings (DCV) to scan eight channels and store the read-
ings in the buffer.
