• For input signals up to +17 dBm (calibrated up to +14 dBm),
use Input 2 .
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.
