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:

.
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
#B0010 - output signal at pin 17
#B0011 - output signal at pin 16 and 17
...
#B1111 - output signal at pin 16, 17, 18 and 19
Range: #B0000 to #B1111 (for setting command), 0 to 15
(query)
*RST: #B0000 (0)
