Model 2750 Multimeter/Switch System User’s Manual
Scanning
7-31
For the 4-wire resistance function, channels 101through 110 will be paired to chan-
nels 111 through 120. ROUT:SCAN? returns the following scan list:
(@101:110)
Now assume the scan is returned to DCV function as follows:
SENS:FUNC ‘VOLT’,(@101:120)
The above command sets channels 101 through 120 for DCV. However, it will
NOT affect the scan list. ROUT:SCAN? still returns a 10 channel scan list:
(@101:110)
The following command will set the scan list for 20 channels:
ROUT:SCAN (@101:120)
b.
ROUTe:SCAN:TSOurce <list>
<list> =
IMMediate
=
HLIMit1, HLIMit2, LLIMit1, LLIMit2
As with front panel operation, the scan can start immediately when it is enabled
and triggered, OR it can be started by a reached reading limit detected by the mon-
itor channel. For immediate, the IMMediate command must be the only parameter
in the list. To use reading limits, each limit must be separated by a comma (,).
Examples:
ROUT:SCAN:TSO IMM
' Start scan when it is enabled and
triggered.
ROUT:SCAN:TSO HLIM1,LLIM1
' Enable high limits 1 and low
limits 1.
Note that any reached limit will start the scan.
c.
ROUTe:MONitor <clist> — The channel that you specify as the monitor must be a
channel that is in the scan list. If it is not, the first channel in the scan list will auto-
matically become the monitor channel.
If the <clist> has more than one channel, error -223 (too much data) occurs and the
command is not executed.
d. ROUTe:MONitor:POINts — Use this command to specify the number of channels
to scan each time the monitor scan is triggered to start. For example, assume the
monitor scan list has 10 channels. To scan that list once, send ROUT:MON:POIN
10. To scan that list twice, use parameter value 20. For three scans, send parameter
value 30, and so on.
