SPG600 & SPG300 Sync Pulse Generators User Manual 2-3
Reference Indicators
The reference indicators indicate whether the sync pulse generator is locked to its
internal oscillator or an external reference signal.
INT.REF. This indicator lights when the sync pulse generator is using its internal
reference oscillator.
EXT.REF. This indicator lights when the sync pulse generator is locked to an
external reference signal. A blinking indicator means that the sync pulse generator
is using the external reference signal but is unable to lock to the signal.
