description:
Sets the Return Loss Reference, the return loss value of your reference reflector.
For example, the Keysight 81000BR reference reflector provides an accurate and stable 0.18 dB reference.
Use [
l
] to set the return loss value of your reference reflector for an external source or the upper or lower wavelength laser
source of a dual return loss module.
An external laser source is denoted by
0
.
0
is the default value of [
l
].
A lower wavelength source is denoted by
1
.
An upper wavelength source is denoted by
2
.
parameters:
Sets the Return Loss Reference as a float value in dB
response:
none
example
sens1:ret:corr:refl 0.18DB
affects:
All return loss modules

description:
Returns the Return Loss Reference, the return loss value of your reference reflector.
For example, the Keysight 81000BR reference reflector provides an accurate and stable 0.18 dB reference.
Use [
l
] to query the return loss value of your reference reflector for an external source or the upper or lower wavelength laser
source of a dual return loss module.
An external laser source is denoted by
0
.
0
is the default value of [
l
].
A lower wavelength source is denoted by
1
.
An upper wavelength source is denoted by
2
.
parameters:
none
response:
Returns the Return Loss Reference as a float value in dB
