CONTrol Commands
The
Control...
commands control the VNA User Port.
●
The VNA User Port functionality is offered at the Aux. Port connector that is provi-
ded by hardware option R&S
FPL1-B5 "Additional Interfaces".
This option is not available for the R&S
ZNLE
●
Usage of the Aux. Port as VNA User Port (instead of SA Auxiliary Port) must be
selected in the "Add. Interfaces" tab of the "System Configuration" dialog.

CONTrol:AUXiliary:C[:DATA]
<DecValue>
Sets or queries a channel-dependent eight-bit decimal value to control eight independ-
ent output signals at the Aux. Port connector (lines 8, 9, 10, 11 and lines 16, 17, 18,
19). The output signals are 3.3 V TTL signals which can be used to differentiate
between up to 255 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 and 16
to 19 of the Aux. Port connector.
●
The value defined with
CONTrol:AUXiliary:C[:DATA]
is assigned to the
active
channel (
●
The signals at the Aux. Port 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 differ-
ent channel bits becomes the measuring channel.
●
The signals at the Aux. Port 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.
