AUDIO IN

Two connectors are used to input audio signals to the AF analyzer:

•HI is the main audio signal input connection.

•LO is used for the audio signal reference. Three choices are available using the AF ANALYZER screen’s Audio In Lo field:

• Gnd connects the center pin through approximately 100 Ω to chassis ground.

•Float is a floating input.

•600 To Hi provides a 600 Ω internal load to match an audio source with an output impedance of 600 Ω .

The measured level is the potential between the HI and LO center pins. The shells of both connectors are at chassis ground.

For more information see “AF Anl In” on page 185, and “Audio In Lo” on page 190.

Operating Considerations

Input impedance is switchable between 1 M Ω

in parallel with 95 pF, or 600 Ω

floating.

This port is selected as the AF analyzer’s input using the AF Anl In field on the AF ANALYZER screen.

Signals input to the AF analyzer are routed through different filters, amplifiers, and detectors that affect the displayed measurement.

CAUTION	The maximum level between the HI and LO center pins is 42 V peak (approximately 30
	Vrms). Exceeding this value can cause permanent instrument damage.
