l
]<wsp><value>[dB]
description:
Sets the front panel delta, that is, the loss correction value, for example, due to the front panel connector. Twice this value is
added to the measured Return Loss.
Use [
l
] to set the front panel delta 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 front panel delta as a float value in dB
response:
none
example
sens1:ret:corr:fpd 0.08DB
affects:
All return loss modules

description:
Returns the front panel delta, that is, the loss correction value, for example, due to the front panel connector. Twice this
value is added to the measured Return Loss.
Use [
l
] to query the front panel delta 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.
A lower wavelength source is denoted by
1
.
An upper wavelength source is denoted by
2
.
parameters:
