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 526.
If checked, you have the possibility to define port-specific power levels by selecting
the related ports in the "Advanced Ports (Pb) Power" table. Unselected ports are
driven with the segment-specific power.
●
"Meas Bandwidth" defines the IF filter bandwidth for each individual sweep seg-
ment. See "Bandwidth" on page 536.
●
"NF Virtual Img Rejection" allows you to activate or deactivate virtual image rejec-
tion for individual sweep segments in noise figure channels. If the column is hid-
den, the channel-wide virtual image rejection setting is used.
Enabling "NF Virtual Img Rejection" only takes effect if the channel is configured for
Noise figure measurement, and if either "Noise Figure", "Gain" or "Noise Density"
are measured.
●
"Selectivity" defines the selectivity of the IF filter used for each sweep segment.
See "IF Filter (digital) " on page 537.
●
"LO < > RF" allows you to define segment-specific "Image Suppr." settings; see
"Image Suppr." on page 687.
●
"Segment Bits" enables the definition of a segment-dependent 4-bit binary value to
control four independent output signals at the User Port connector (lines 16, 17,
18, 19; see Chapter 12.3.1.1, "User Port", on page 1779). The output signals are
3.3 V TTL signals which can be used to differentiate between up to 16 independent
analyzer states.
