Control Fields for Analog Measurements

Audio In Lo

This field sets the AUDIO IN LO connector’s state.

Gnd causes the center pin of the connector to be connected directly to chassis ground.

Float isolates the center pin of the connector from ground, providing a floating input to the AF analyzer.

600 To Hi establishes a 600-ohm impedance between the center pins of the AUDIO IN LO and AUDIO IN HI connectors. Also, the Ext Load R field is removed, since the load is now fixed to 600 ohms.

AF ANALYZER

Audio Out

Audio output coupling selects ac or dc coupling of the AF generator to the AUDIO OUT connector.

RF GENERATOR

Auto/Norm

This field specifies how the trigger level is set.

Auto automatically triggers if a triggering signal is not detected within approximately 50 ms of the last trigger.

Norm requires a specific triggering signal before triggering.

Operating Considerations

Automatic triggering should be used for signals >20 Hz. Normal triggering should be used for signals ≤ 20 Hz.

Also, when measuring ≤ 1 Hz signals, you should set the Scope To field in the AF ANALYZER screen to Input to provide dc coupling to the oscilloscope’s input.
