Output to Input Synchronization
The feature S YNCH W / V 1 A C synchronizes the output frequency with the
V1AC input frequency (refer to ”Sync w/ V1AC” on page 3-10).
The Amplifier test card provides the possibility to synchronize to various inputs.
CPC 100 filters the input signals, therefore, if mains is connected to, for
example, the V1 AC input, possible signal interferences and / or noise do not
affect the synchronization considerably. The ground wave of the input signal
serves as reference for the synchronization.

Output to input
synchronization
How long does the synchronization take?
Example for the 2kV AC output in Quick:
As explained on page 14 of this chapter, the 2kV AC output needs 1200ms to
ramp up to its full magnitude, and accordingly less for a smaller magnitude.
Total synchronization time = time to reach 5% of full magnitude + settling time.
• The output ramps linear, therefore reaches 5% of its full magnitude after 5%
of 1200ms = 60ms
• Then the 100ms settling time elapses
• Therefore, the entire synchronization lasts 60ms + 100ms = 160ms.
