Configure The Trigger Out Signal - Quantifi Photonics BERT 1005 Series User Manual

Each time the data rate is changed, the clock synthesizer is unlocked for the frequency to change, and
then locked once the frequency is set. The lock status is indicated by the SYNTHESIZER VCO LOCK
indicator on the CLOCK tab.
After changing the frequency, the lock indicator turns to dark green ( ), and once the synthesizer is
locked to the new frequency it turns to light green ( ).
