Frequency Reference Source

The FieldFox internal frequency reference source is used to make accurate and
stable measurements. To improve measurement accuracy and stability, you
can use a highly-stable external 10 MHz reference source or a precision timing
signal provided with Built-in GPS (Opt. 307).
The Frequency Reference setting will survive a Factory Preset or Mode Preset
and is saved as part of the Instrument State. When resuming after Standby, the
FieldFox will display an Unlock message while it acquires a lock to an external
or GPS source.
