CPC 100 V1.4116 - 20Output to Input SynchronizationThe feature S Y N C H W / V 1 A C synchronizes the output frequency with theV1AC 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, forexample, the V1 AC input, possible signal interferences and / or noise do notaffect the synchronization considerably. The ground wave of the input signalserves as reference for the synchronization.Table 13:Output to inputsynchronizationHow 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 toramp 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.Test cards Quick,SequencerTest card AmplifierFrequency Range 48 ... 62HzSynchronization inputs V1AC(automatic range switching)V1AC, V2AC, IAC(fixed to maximum range)Input magnitude 10% of input range full scaleOutput magnitude 5% of output range full scaleSettling time 100ms after 5% ofoutput magnitude isreached1000ms after 5% ofoutput magnitude isreachedSignal changes All quantities must beramped within 20 signalperiodsNo changes offrequency and phase.Magnitude changeswithout limitation.
