RelativeLEVel
Description
This command sets WDM analysis bandwidth
position for all channels to a specific value.

relative to peak maximum where signal bandwidth
of a channel is computed.
At *RST, this value is set to 3.0 dB for bandwidth1
and 20.0 dB for bandwidth2.
Syntax
:CALCulate[1..n][:WDM]:BANDwidth[1|2]|BWIDth[
1|2]:RelativeLEVel<wsp><PowerLevel[<wsp>DB|
W/W|PCT]>|MAXimum|MINimum|DEFault
Parameter(s)
PowerLevel:
The program data syntax for <PowerLevel> is
defined as a <numeric_value> element followed
by an optional <SUFFIX PROGRAM DATA>
element. The allowed <SUFFIX PROGRAM
DATA> elements are: DB|W/W|PCT. The
<PowerLevel> special forms MINimum,
MAXimum and DEFault are accepted on input.
MINimum allows to set the instrument to the
smallest supported value.
MAXimum allows to set the instrument to the
greatest supported value.
