Using the Multiplexer
45
Scanning Channels
Scanning the Multiplexer channels consists of sequentially closing a channel
(and its associated tree relays), making some measurement , opening that
channel, and then repeating that process with the next channel in a channel
list. You can make a single scan through the channel list or scan a multiple
number of times. You can also scan the channel list continuously until the
scan is aborted.
The
TRIGger:SOURce
command specifies the source to advance the scan.
The
OUTPut
command can be used to enable the E1406A Command
Module's “Trig Out” port, TTL Trigger bus line (0-7) or ECL Trigger bus
lines (0-1). Figure 2-7 illustrates the commands in the scanning sequence.
