PRODUCT DESCRIPTION

The PB-4281 PC board and SC-02 Signal Conditioner form a high precision two channels A/D-D/A audio front-end for your IBM or compatible PC.

The PB-4281 PC board is housed in a standard PCI slot inside your computer and performs precise 18-bit digitizing of the signals to be analyzed.

The SC-02 Signal Conditioner is software controlled via an USB serial link; it is equipped with an instrument grade input and output analog circuitry with an exceptionally wide range of output attenuation and input gain that allows an easy interface to the outer world; the input and output loopback capability with the internal ultra stable voltage reference permit a simple and precise calibration of the whole instrument; the two input channels can be controlled separately or as a single balanced one.
A switchable phantom supply lets you directly connect an Audiomatica MIC-01 or MIC-02 or MIC-03 microphone to any of the SC-02 input.
It is also possible to superimpose a DC voltage to the genarated AC signal.
