CANalyzer subsystem
:PATH:GAIN:MODE <string>
:PATH:GAIN:MODE?
These commands set/query the mode of the Gain field, allowing you to
choose between an autoranging gain (‘Auto’) or a fixed gain (‘Hold’).
This command may conflict with the code domain analyzer’s settings
CDAN:PATH:GAIN and CDAN:PATH:MODE. For example, if
autoranging is turned off (‘Hold’) in the CDMA analyzer and turned on
in the Code Domain Analyzer (‘Auto’), the ‘Hold’ setting will always
override the ‘Auto’ setting. When autoranging is turned off, setting
either analyzer’s path gain will automatically change the other’s to the
same setting.
For average power measurements, use the CAN:POW:GAIN:MODE
command.
Syntax
CAN:PATH:GAIN:MODE ‘Auto’
‘Hold’
CAN:PATH:GAIN:MODE?
Screen/field equivalent
CAN:PATH:GAIN:MODE sets the Auto/Hold subfield of the Gain field
of the CDMA ANALYZER or CODE DOM screen.
:PNINcrement <real number>
:PNINcrement?
These commands set/query the PN increment. If you know the PN
increment, enter it with this command to speed the PN offset search. If
you do not know the increment, enter a 1.
This command utilizes the :INCR command of the “Real Number
Setting Syntax” on page 299.
Syntax
CAN:PNIN <real number> !values from 1 to 256
CAN:PNIN? !returns the value of the PN increment
Screen/field equivalent
CAN:PNIN:INCR controls the PN Incrment field on the CDMA
ANALYZER. This field is displayed only when the Find PN field is set to
Auto.
