Refer to the following sections:
●
Chapter 10.5.2.2, "Define Segments dialog"
●
Optional Columns
Each selected (checked) option adds a column to the segment list and the point list.
●
"Name" allows you to assign a name to each segment. A segment name is a string
that is allowed to contain letters, numbers and special characters.
●
"Power (Pb)" allows you to define the internal source power (channel base power)
for each individual sweep segment. See
●
"Meas Bandwidth" defines the IF filter bandwidth for each individual sweep seg-
ment. See
●
"Selectivity" defines the selectivity of the IF filter used for each sweep segment.
See
●
"LO < > RF" allows you to define segment-specific "Image Suppr." settings; see
●
"Segment Bits" enables the definition of a segment-dependent 4-bit binary value to
control four independent output signals at the Aux. Port connector (lines 16, 17, 18,
19; see
on page 1110). The output signals are 3.3 V
TTL signals which can be used to differentiate between up to 16 independent ana-
lyzer states.
For an application example, refer to the detailed remote control description
(
OUTPut<Ch>:UPORt:SEGMent<Seg>[:VALue]
Setting the segment bits does not change the analyzer state.
●
"Time" defines the sweep time for each segment. The default configuration for a
new segment is equal to the sweep time setting for unsegmented sweeps; see
When "Time" is checked, two new columns appear in the table. The first column is
titled "Segment Time" or "Meas Delay", depending on the selected radio button
below the "Time" checkbox. The second column is titled "Auto" and is used to acti-
vate automatic sweep time setting.
"Segment Time" is the total measurement time for the sweep segment. The mini-
mum segment sweep time to be set is equal to the estimated value in "Auto" mode.
"Meas Delay" sets a delay time allowing the DUT to settle before the hardware set-
tings of the analyzer are changed and a new partial measurement is started.
Changing the "Meas Delay" modifies the "Segment Time" and vice versa.
"Auto" minimizes the sweep time. If "Auto" is selected for a segment, the columns
