:CHANnel<n> Commands 10
Keysight InfiniiVision 4000 X-Series Oscilloscopes Programmer's Guide 303
Introduction to
:CHANnel<n>
Commands
<n> ::= 1 to (# analog channels) in NR1 format
The CHANnel<n> subsystem commands control an analog channel (vertical or
Y-axis of the oscilloscope). Channels are independently programmable for all
offset, probe, coupling, bandwidth limit, inversion, vernier, and range (scale)
functions. The channel number (1, 2, 3, or 4) specified in the command selects the
analog channel that is affected by the command.
A label command provides identifying annotations of up to 10 characters.
You can toggle the channel displays on and off with the :CHANnel<n>:DISPlay
command as well as with the root level commands :VIEW and :BLANk.
Reporting the Setup
Use :CHANnel1?, :CHANnel2?, :CHANnel3? or :CHANnel4? to query setup
information for the CHANnel<n> subsystem.
Return Format
The following are sample responses from the :CHANnel<n>? query. In this case,
the query was issued following a *RST command.
