Product introduction

PB-4281 interface card and SC-02 signal analyzer is composed of a double channel A/D D/A audio analyzer of high precision and your computer connection.

PB-4281 interface card is a standard PCI card, installed on your computer is composed of 18 bit digital signal analyzer precision.

The USB implementation of SC-02 control power supply and signal analyzersoftware, through the audio interface easy to achieve wide attenuation of outputand input gain, input and output circuit

The voltage reference points inside an extremely stable, simple and precisecorrection. Dual channel unbalanced input can be converted to a single channel balance input.

Can input program can be directly connected to the Audiomatica phantom power supply MIC-01, MIC-02 or MIC-03 and SC-02.

You can load the DC signal to AC signal output.
