■AUTOTEST OPERATION

General Autotest features

For Autotest to function, all instruments involved in the test must be Agilent Handheld instruments with an Autotest function.

The Autotest feature performs automated measurement (and automatic λ detection) by data exchange between instruments, and requires minimal operator knowledge: turn the instrument on, connect a test lead, and select AUTOTEST on the source. Subsequent operation is automated, although some choices can be made for convenience.

Functionality is determined by the options fitted to the instrument(s) used. Autotest configures itself according to the options available, and carries out the most comprehensive test possible.

Autotest remains synchronised for about 8 seconds, which enables the user to change optical connections without re-starting Autotest each time.

A light source transmits Autotest signals at one or two wavelengths to an appropriate power meter.

Operation

Turn on the source and meter, and connect them with a test lead. On the light source, push AUTOTEST.

This is all that is required to start Autotest operation on the power meter.

The meter will automatically set to the correct λ and display absolute power in dBm. The display will alternate between wavelengths. To display only one λ at a time, push +/-.

You may also select AUTOTEST on the meter, which forces the meter into Autotest mode, with faster synchronisation in this mode (the source must be in Autotest mode). Push MENU to exit.

The source power transmitted from the source is displayed on the left hand side of the display.

Push ABS/REL to make the meter display relative power.

The stored reference value(s) are displayed on the left hand side of the display.

To take a reference under Autotest, connect the source and
