Receiver Wavelength (nm)
Set the wavelength of to be used by the optical power meter.
RF Power
Forward RF Power [dBm]
Sets the RF power level for the source port.
For balanced measurements (on 4-port network analyzers),
Ports 2 and 3 of the network analyzer are forward for EO
measurements and reverse for OE measurements.
Increasing the forward RF power for OE measurements
increases the optical modulation amplitude.
Reverse RF Power [dBm]
Sets the RF power level for the receiver port.
We recommend the factory calibrated default value for the best
results.
To reset to the factory default, leave the text box empty or enter
a value less than -200 dBm.
