Note
Power splitters have a coupling factor of 0 dB.
Figure 1-12 shows the input p ower versus output voltage
characteristics for typical HP/Agilent dio de detectors. From the
chart, the leveled power at the dio de detector input resulting from
any external level voltage setting may b e determined. The range of
power adjustment is approximately
0
30 dBm to +18 dBm.
Hint
Automatically characterize and comp ensate for the detector
used by performing a detector calibration. Refer to \Using
Detector Calibration" in the \Optimizing Swept Signal Generator
Performance" section.
