CALibration Subsystem

Before executing this command, connect a cable between front panel connector

AMPTD REF OUT and the INPUT connector for all Agilent EMC analyzers except

Agilent model E7401A. If the cable is not connected, the alignment will fail.

Access: System, Alignments, Align Now, RF

Select the Source State for Calibration

:CALibration:SOURce:STATe OFF|ON|0|1

:CALibration:SOURce:STATe?

Controls the state of the 50 MHz alignment signal.

NOTE The alignment signal is internally switched to the INPUT for Agilent model

E7401A. For all other models, connect a cable between front panel connector

AMPTD REF OUT and the INPUT connector before performing a calibration.

Factory Preset

and *RST: Off

Front Panel

Access: For Agilent EMC model E7401A:

Input/Output (or Input), Amptd Ref (f=50 MHz) On Off

For all other Agilent EMC models:

Input/Output (or Input), Amptd Ref Out (f=50 MHz) On Off

Calibrate the Tracking Generator

:CALibration:TG

:CALibration:TG?

Performs an alignment of the tracking generator assembly.

The query performs the alignment and returns a zero if the alignment is successful.

NOTE This command is applicable on all Agilent EMC models except E7401A with

Option 1DN installed. Before executing this command, connect a cable between

front panel connector RF OUT and the INPUT connector. The alignment will fail

using command CAL:TG if the cable is not connected.
