Scanning Channels (E1468A Only):
•
For a single channel, use [ROUT:]SCAN (@ssrc)
•
For multiple channels, use [ROUT:]SCAN (@ssrc,ssrc,...)
•
For sequential channels, use [ROUT:]SCAN (@ssrc:ssrc)
•
for groups of sequential channels use [ROUT:]SCAN
(@ssrc:ssrc,ssrc:ssrc).
You can use any combination of these commands. However, closure
order for multiple channels with a single command is not guaranteed.
Scanning Channels (E1469A Only):
•
For a single channel, use [ROUT:]SCAN (@ssrrcc)
•
For multiple channels, use [ROUT:]SCAN (@ssrrcc,ssrrcc,...)
•
For sequential channels, use [ROUT:]SCAN (@ssrrcc:ssrrcc)
•
for groups of sequential channels use [ROUT:]SCAN
(@ssrrcc:ssrrcc,ssrrcc:ssrrcc).
You can use any combination of these commands. However, closure
order for multiple channels with a single command is not guaranteed.
Scanning Operation:
When a valid channel_list is defined,
INITiate[:IMMediate] begins the scan and closes the first channel in the
channel_list. Successive triggers from the source specified by
TRIGger:SOURce advance the scan through the channel_list. At the end
of the scan, the last trigger opens the last channel.
Stopping Scan:
See ABORt.

*RST Condition:
All channels open.
Example
Scanning Channels
This example sets the channels to be scanned from 100 to 200 for a
single-module switchbox and initiates the scan sequence.
SCAN (@100,200)
!Set scan sequence from ch 100
through 200
INIT
!Begin scan and close ch 100
