:CALCulate[1..n][:WDM]:DATA:CHANnel:
BANDwidth[1|2]|BWIDth[1|2]
[:WAVelength]?
Description This query returns computed WDM analysis result
for wavelength bandwidth of the selected
channel.
At *RST, this value is not available.
Syntax :CALCulate[1..n][:WDM]:DATA:CHANnel:BANDw
idth[1|2]|BWIDth[1|2][:WAVelength]?
Parameter(s) None
Response Syntax <Bandwidth>
Response(s) Bandwidth:
The response data syntax for <Bandwidth> is
defined as a <NR3 NUMERIC RESPONSE
DATA> element.
The <Bandwidth> response corresponds to the
computed wavelength bandwidth in meter.
Example(s) CALC:CHAN:DEL:ALL
CALC:CHAN:DEF "CWDM_16", 1550.000 NM
CALC:BAND2:RLEV 10.0 DB
<Do measurement>
CALC:DATA:CHAN:SEL "CWDM_16"
CALC:DATA:CHAN:BAND1:WAV? Returns
3.000000E-011
CALC:DATA:CHAN:BAND2:WAV? Returns
5.400000E-011
