Characteristics
Signal Inputs
The signal inputs of Type 2719 have a minimum input impedance of 10 kΩ. The AC signal
input is for connecting a vibration exciter controller or generator and is capacitive-coupled
giving a –0.5 dB lower limiting frequency of approximately 15 Hz. The DC signal input is
direct-coupled enabling a DC offset voltage to be applied for centring vibration exciter tables,
which are statically displaced by heavy test objects.
The maximum input voltage for both inputs is 3.4 V peak. At higher input levels, the drive
signal is clipped causing the Distortion lamp to light.
