Vector Detector

VD series

VD-291f2
VD-291F2

The VD-291 series detects the quadrature phase using The CD-552 series. The amplitude and the phase of the input signal synchronous with a reference signal are calculated by a DSP from the result.

Model	Input impedance	Input signal	Detection frequency range	Gain
VD-291F2	5kΩ	CMOS(0/ 5V)level, Square wave	100Hz to 20kHz	x 1, x 10 and external Setting
VD-291F3	5kΩ		1kHz to 200kHz
VD-291F4	1.25kΩ		10kHz to 2MHz
