Switch one or more local oscillator stages on or off.

Arguments:

Receivers ant

The set of receivers whose oscillators are to be controlled.

LoStages stages

The oscillator stages to be enabled or disabled. This is a the set of one or more of:

• if - The local-oscillator IF-monitor output.
• sweep - The sawtooth used to acquire phase-lock.
• gunn - The gunn-diode.
• all - All of the above stages.

SwitchState state

The desired state of the selected stages: on or off.

Example:

The following example turns on all except the sweep stages of all local oscillators.

 lo all, all-sweep, on

Context:

On power-up the local oscillator IF and sweep stages are enabled, but the gunn stage is disabled. The gunn stage must be enabled before observing.
