RF Network Analyzers
In Case of Difficulty
• With the power meter connected to PORT 1 (REFLECTION port on the ET models),
check for available power and modulator functionality by adjusting the power DAC
from 0 to 4095.
The power should vary from −20 dB to +4 dB from the maximum specified power in
most cases. (At some of the frequencies you may not be able to tune above maximum
power.)
• If your analyzer is not operating correctly, as indicated from the results of the previous
step, refer to Chapter 7 , “Source Troubleshooting,” or contact the nearest Agilent
Technologies sales or service office.
