Synchronizing Time Constant Measurement

[PrescottDan]

What kind of circuits you want to measure the time constant of a synchronized signal or waveform?

I know in the past i have measure it for servo loops

I guess you need an impulse to unbalance the synchronised circuits then a scope (or such like) to see how long the system takes to revert to its synchronised state. A stop watch and a DVM? depends on the lockup time?

Can't you just disconnect and then reconnect the Synchronized signal to measure the Time it takes for the circuit to get in a synchronized state?

Only if the disconnection/reconnection time is not more then a few percent of the lock up time.
