CONFigure:CHANnel<Ch>[:STATe] <Boolean>
Creates or deletes channel no. <Ch> and selects it as the active channel.
CONFigure:CHANnel<Ch>:NAME
defines the channel name.
A channel created with
CONFigure:CHANnel<Ch>[:STATe] ON
can be configured but has no
trace assigned so that no measurement can be initiated. Use
CALCulate<Ch>:PARameter:SDEFine "<Trace_name>,"<Parameter>"
to create a new
channel and a new trace.
In remote control it is possible to remove all channels. This is in contrast to manual control
where at least one channel with one diagram area and one trace must be available.
<Ch> Number of the channel to be created or deleted.
<Boolean>
ON | OFF - Create or delete channel.
*RST value ON for channel no. 1 (created on *RST), OFF for all other
channels.

CONTrol...
This subsystem provides device-specific commands to control hardware settings related to the rear
panel connectors.
CONTrol:AUXiliary:C[:DATA] <numeric_value>
Sets or queries a channel-dependent four-bit decimal value to control four independent output signals
at the USER CONTROL connector (applied to pins 8, 9, 10, 11). The output signals are 3.3 V TTL
signals which can be used to differentiate between up to 16 independent analyzer states.
CONTrol:AUXiliary:C[:DATA]
itself does not change the analyzer state.
Channel bit definition and activation
The channel bits have the following properties:
•
After a *RST of the analyzer all channel bits (including the value for the active, sweeping
channel no. 1) are set to zero; no signal is applied to pins 8 to 11 of the USER CONTROL
connector.
•
The value defined with
CONTrol:AUXiliary:C[:DATA]
is assigned to the active channel
(
INSTrument:NSELect <Ch>
).
•
The signals at the USER CONTROL connector reflect the channel bits of the measuring
channel, i.e. the channel for which the analyzer performs a sweep. This channel is not
necessarily identical with the active channel.
•
The signals are switched on as soon as a measurement (sweep) in a channel with non-zero
channel bits is started. They are changed whenever a channel with different channel bits
becomes the measuring channel.
•
The signals at the USER CONTROL connector are maintained after the analyzer enters the
hold state. This happens if all channels use single sweep mode and if all sweep sequences
have been terminated.
