For M9484C with Option AL2.
The instrument contains two connectors labeled LO1 and LO2 for providing an Auxiliary Local Oscillator output. Each connector can be off, or provide a CW frequency of 2.4 GHz, 4.8 GHz, 9.6 GHz, or 19.2 GHz. If you are not using the output, place the setting to off to minimize emissions.
When using the V3080A Frequency Extender, the Auxiliary LO connector(s) are used for interfacing with V3080A. With a V3080A connected, the auxiliary LO port is set to 9.6 GHz and is not changeable.
When one V3080A is connected to the instrument, the LO1 will be used. If a second V3080A is connected, LO2 will be used.
You can connect one or two V3080As to a 2-Channel M9484C VXG.
If you want to connect a single V3080A to a 2-Channel M9484C, then you must connect it to Channel 1 of M9484C.
The characteristics of the cable used to provide the IF to the V3080A must be entered into the instrument’s software. If you are using the 1 Meter, 2 Meter, or 3 Meter cabled purchased from Keysight Technologies, the .s2p characteristics are included in the instrument’s software. If you are using a cable obtained elsewhere, select Custom and provide the path to the .s2p file in the Custom Cable File setting.

If a custom cable is selected as the IF cable, the .s2p file of the cable’s characteristics must be copied into the instrument and specified to the instrument’s software with path and filename. Once a V3080A has been detected, Custom Cable Files should be stored in the ExternalUpconverter directory of the Corrections Folder.
The following table shows some of custom cable file path examples and the folders from which these files are selected.
