:GAIN:MODE <string>
: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 CDMA analyzer’s settings
CAN:PATH:GAIN and CAN: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
CDAN:GAIN:MODE ‘Auto’
‘Hold’
CDAN:GAIN:MODE?
Screen/field equivalent
CDAN:GAIN:MODE sets the Auto/Hold subfield of the Gain field of the
CODE DOM screen, when the CDMA standard is set to “IS-95 Only”.
:GAIN:VALue?
This command queries the gain of the code domain analyzer. This
command will only be enabled when autoranging is turned on
(CDAN:GAIN:MODE ‘Auto’).
Syntax
CDAN:GAIN:VAL? !returns 0 dB,6 dB,12 dB,18 dB,24 dB, 30 db,
36 dB
Screen/field equivalent

CDAN:GAIN:VAL? reads the lower subfield of the Gain field of the
CODE DOM screen when the upper subfield is set to Auto,
