Tools
Some of the controls that can be selected on the Tools tab are also
available on the measurement tabs. The controls on the measurement tabs
are activated when you start the next measurement setup. The controls on
the Tools tab are activated immediately.
The Tools tab always showing the current settings of the instrument. These
may be different to what is selected on the other tabs.
Receiver
Receiver Wavelength (nm)
Set the wavelength to be used by the optical power meter.
RF Power
Forward RF Power [dBm]
Sets the RF power level for the source port(s).
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(s).
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.
