Analog Measurements - Screens and Control Fields

Control Fields for Analog Measurements

Filter 2

This field selects an audio frequency filter which can be used to condition the audio signal before it is analyzed by the audio frequency analyzer.

The following filter choices are available:

300Hz LPF

3kHz LPF

15kHz LPF

> 99kHz LP

6 kHz BPF

Operating Considerations

The audio from the Test Set’s speaker is not affected by Filter 1 or Filter 2 settings.

AF ANALYZER

FM Coupling

This field alters the FM modulator to allow DCFM from internal and external modulation sources. The upper subfield selects ac or dc coupling between the RF generator’s frequency modulator and the ANALOG MODULATION IN connector. The lower subfield, DC FM Zero, zeroes any dc bias that exists when FM Coupling is set to DC.

Operating Considerations

This field should be set to DC whenever the AFGen2 To field is set to FM; this provides better modulation response at low data rates.
