OUTPut<Ch>:UPORt:SEGMent<Seg>[:VALue] <BinValue>
Sets or queries a sweep segment-dependent four-bit binary value to control four inde-
pendent output signals at the USER PORT connector (lines 16, 17, 18, 19). The output
signals are 3.3 V TTL signals which can be used to differentiate between up to 16 inde-
pendent analyzer states for each channel. The command is valid for segmented fre-
quency sweeps. It is analogous to the channel-dependent command
OUTPut<Ch>:UPORt[:VALue]
.
The bits for the sweep segments must be enabled explicitly using
OUTPut<Ch>:UPORt:SEGMent:STATe
.
Segment bit definition and activation
The segment bits have the following properties:
●
After a
*RST
of the analyzer all segment bits are set to zero; no signal is applied to
pins 16 to 19 of the USER PORT connector.
●
The value defined with
OUTPut<Ch>:UPORt:SEGMent<Seg>[:VALue]
is
assigned to segment no.
<Seg>
in channel no.
<Ch>
.
●
The signals at the
USER CONTROL
connector reflect the segments bits of the cur-
rently measured segment.
●
The signals are switched on as soon as a measurement in a segment with non-
zero segment bits is started. They are changed whenever a segment with different
segment bits is measured.
●
The signals at the USER PORT connector are maintained after the analyzer enters
the hold state. This happens in single sweep mode after all sweep sequences have
been terminated.
Tip:
You can use the active segment number as a parameter for
OUTPut<Ch>:UPORt:SEGMent<Seg>[:VALue]
and monitor the measurement in up
to 16 different segments per channel at the USER PORT connector; see example
below. You can also use the USER PORT output signals as segment-dependent trigger
signals for external devices. Use
CONTrol:AUXiliary:C[:DATA]
to transfer the
four bit value in decimal representation.
Suffix:
<Ch>
.
Channel number.
<Seg> Sweep segment number
Parameters:
<BinValue> Binary value. The transferred values correspond to the following
states of the USER CONTROL connector:
#B0000 - no signal at any of the four pins 16, 17, 18, 19
#B0001 - output signal at pin 16
