CDANalyzer subsystem
:SCALe:TIME <string>
:SCALe:TIME?
These commands set/query the time per division portion of the scale 
that is used when measuring code domain timing.
Syntax
CDAN:SCAL:TIME ‘1 ns’
 
‘2 ns’
 
‘5 ns’
 ‘10 
ns’
 ‘20 
ns’
 ‘50 
ns’
CDAN:SCAL:TIME?
Screen/field equivalent
CDAN:SCAL:TIME controls the 
Time/div
 field on the Marker menu of 
the CODE DOM screen when the CDMA standard is set to “IS-95 
Only”. This field is displayed only when a timing measurement is 
selected
:THRShld <real number>
:THRShld?
These commands set/query the minimum display threshold for code 
domain timing and phase measurements. Walsh channels that have 
power levels below the threshold are not displayed in the timing and 
phase displays. Querying these measurements for Walsh channels that 
are below the threshold level using GPIB will return a default value of 
9e99.
Syntax
CDAN:THRS <real number> !values minus 30 to 0.0 dB
CDAN:THRS?
Screen/field equivalent
CDAN:THRS controls the 
Threshold
 field on the 
Aux
 menu of the 
CODE DOM screen when the CDMA standard is set to “IS-95 Only”.
