This chapter explains techniques to scan relay matrix channels and shows
how to use the Scan Complete bit. It also explains the response of the
switchbox instrument to special 488.2 commands and the SCPI
query. The chapter contents are:

Scanning relay matrix channels consists of closing a set of channels one at a
time. Single scan, multiple (2 to 32767) scans, or continuous scanning
modes are available. See Figure 4-1 for scanning commands.
The
TRIG:SOUR
command specifies the source to advance the scan. You
can use the
command to advance the scan when
TRIG
is set. The

sources.
Scanning relay matrix channels has the same effect as executing multiple
commands. Thus, scanning is useful when the outputs from a
