<Ch>
Channel number.

Sweep segment number. This suffix is ignored; the setting is valid for all
segments.
<Boolean>
ON | OFF - Enables or disables segment bits.

Types
Device-specific, command or query
Example:
See OUTPut<Ch>:UPORt:SEGMent<Seg>[:VALue]
OUTPut<Ch>:UPORt:SEGMent<Seg>[:VALue] <numeric_value>
Sets or queries a sweep segment-dependent four-bit binary value to control four independent output
signals at the USER CONTROL connector (pins 16 to 19). The output signals are 3.3 V TTL signals which
can be used to differentiate between up to 16 independent analyzer states for each channel. The
command is valid for segmented frequency sweeps. It is analogous to the channel-dependent command
OUTPut<Ch>:UPORt[:VALue] (for unsegmented sweeps).
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 CONTROL 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 currently
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 CONTROL connector are maintained after the analyzer enters the hold
state. This happens in single sweep mode after all sweep sequences have been terminated.
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 CONTROL connector; see example below. You can also use the
USER CONTROL output signals as segment-dependent trigger signals for external devices. Use
CONTrol:AUXiliary:C[:DATA] to transfer the four bit value in decimal representation.
<Ch>
Channel number.
<Seg>
Sweep segment number
<numeric_value>
Binary value.
Range [def. unit]
#B0000 to #B1111 (for setting command), 0 to 15 (query) [–]
The transferred values correspond to the following states of the USER
CONTROL connector:
