To level externally:

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

2.Refer to menu map 1.

3.Press (ALC).

4.Select Leveling Point ExtDet .

5.Set the coupling factor. Select Coupling Factor c-) @ @ (dB(m)).

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.
