To level externally:
1. Setup the equipment as shown. For this example, the
detector/coupler setup is used.

Note
Power splitters have a coupling factor of 0 dB.
Figure 1-12 shows the input power versus output voltage
characteristics for typical HP diode detectors. From the chart,
the leveled power at the diode detector input resulting from any
external level voltage setting may be determined. The range of power
adjustment is approximately -30
dBm
to i-18
dBm.
Hint
Automatically characterize and compensate for the detector used by
performing a detector calibration. Refer to “Optimizing Synthesizer
Performance, Using Detector Calibration,” later in this section.
