LBNoise
In addition to the switches, all amplifiers are turned off. Results
in lower broadband noise.
Manual operation:
See
OUTPut<Ch>:UPORt:SEGMent<Seg>:STATe
<Boolean>
Enables or disables segment bits for the sweep segments in channel no.
<Ch>
; see
OUTPut<Ch>:UPORt:SEGMent<Seg>[:VALue]
. The command is valid for segmen-
ted frequency sweep.
Suffix:
<Ch>
.
Channel number.
<Seg>
Sweep segment number. This suffix is ignored; the setting is
valid for all segments.
Parameters:
<Boolean>
ON | OFF - Enables or disables channel bits.
*RST:
OFF
Example:
See
OUTPut<Ch>:UPORt:SEGMent<Seg>[:VALue]
Manual operation:
See
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.
