The FieldFox can phase lock with an external 10 MHz reference signal. When a high-
stability 10 MHz reference signal is available, this can improve the accuracy and
stability of measurements in CAT and NA Modes.
The External Reference setting will survive a FieldFox or Mode Preset and is saved as
part of the Instrument State.
