Refer to the following sections:
●
Chapter 10.5.2.2, "Define Segments dialog", on page 333
●
"Show Point List..." on page 335
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 "Power" on page 313.
●
"Meas Bandwidth" defines the IF filter bandwidth for each individual sweep seg-
ment. See "Bandwidth" on page 322.
●
"Selectivity" defines the selectivity of the IF filter used for each sweep segment.
See "Selectivity " on page 323.
●
"LO < > RF" allows you to define segment-specific "Image Suppr." settings; see
"Image Suppr." on page 530.
●
"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 Chapter 14.2.1.1, "Aux. Port", 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
"Sweep Time / Auto" on page 326.
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
"Segment Time" or "Meas Delay" (in the "Define Segments" dialog cannot be edi-
