Lxm

provides a tabular listing of alI the measured data points and

 

their current values, together with limit information if it is

 

turned on. At the same time, the screen menu is presented, to

 

enable hard copy listings and access new pages of the table. 30

 

lines of data are listed on each page, and the number of pages is

 

determined by the number of measurement points specified in

 

the stimulus menu.

 

provides two user-delinable arbitrary frequency list modes.

 

This list is defined and modified using the edit list menu and

 

the edit subsweep menu. Up to 30 frequency subsweeps

 

(called “segments”) of several different types can be specified,

 

for a maximum total of 1632 points. One list is common to

 

both channels. Once a frequency list has been defined and a

 

measurement calibration performed on the full frequency list,

 

one or all of the frequency segments can be measured and

 

displayed without loss of calibration.

 

For more information on the different list frequency sweep

 

modes, refer to “Sweep Type Menu” in Chapter 6, “Application

 

and Operation Concepts. n

 

enables or disables the ability to set independent IF bandwidths

 

for each segment in a swept list measurement.

 

enables or disables the ability to set independent power levels

 

for each segment in a swept list measurement.

 

When on, sets power range mode to manual to set a range

 

for the power values. (The range can be chosen using the

 

‘PTFR ‘MGE key.) The power values can be entered using the

 

“/” ” ”

 

.~~~,..~.~~~... key. If ports are uncoupled, the power can be

 

set independently for each port.

 

i.:, .*<.; ..::< ..: ,::: ::. .)

 

When off, the .$&#!@E $Y@H$IKkey will not function and the

 

power column in the swept list table will display asterisks. In

 

this case, the power is set by the normal test port power value.

 

selects either stepped or swept list mode. For in-depth

 

information on swept list mode, refer to “Swept List Frequency

 

Sweep” in Chapter 6, “Application and Operation Concepts. n

 

provides a tabular listing of all the measured data points and

 

their current values, together with limit information if it is

 

switched on. Thirty lines of data are listed on each page,

 

and the number of pages is determined by the number of

 

measurement points specified in the stimulus menu.

 

measures the TRL/LRM line or match standard for PORT 1.

 

measures the TRLLRM line or match standard for PORT 2.

 

turns the LO control mode on and off for frequency offset.

 

leads to the Lo menu. Allows you to configure the external

 

source for frequency offset.
