3. Verify power supply settings and connect the cables to the ±5V power supplies
and to ground.
4. Connect RF output connector (SMA, 50
Ω
impedance).
5. Connect monitor output connectors (SMA, 200
Ω
impedance).
Note that the gains of the monitor outputs have been set to compensate for
differences in the responsivities of the detectors. If the monitor 1 and monitor 2
outputs are equal, the inputs are balanced.
6. Connect optical inputs to the 2 input pigtails. Make sure that optical power levels
are within range and that the two inputs are balanced to within the balanced
saturation power.
