Amplifier
Use the Amplifier test card to set CPC 100 to an "amplifier-like" mode. In this
mode, an input signal fed into a synchronization input drives the high-current
output’s magnitude, frequency and phase angle.
Select between IAC, V1AC and V2ACas synchronization inputs.
To prevent saturation, the output signal follows sudden magnitude changes at
the synchronization input slowly. This smoothening effect delays the follow-up
of the output current up to 250ms.
Both the "amplification" factor and the phase angle between input and output are
set by the user in the Amplifier test card.

Note 1: Changes in frequency and phase angle may result in unwanted
effects. Both frequency and phase must be held stable.
Note 2: The input frequency is limited to a range of 48 ... 62Hz.

Set the amplification factor to determine the ratio between the input and the
output signal.
Note: The synchronization input is not automatically range-switching, it is
fixed to its maximum value.
