Features the dynamic signal conditioning circuit:

4 mA current source for transducer biasing •

•

Hardware detection of a transducer fault

AC Coupling (0.1 Hz or 1 Hz high pass filter) or DC coupling (bypasses the filters)

Programmable gain amplifier (range selection)

Hardware overrange detection

Anti-aliasing low-pass filter

Simultaneous sample-and-hold (SSH) amplifier

Support for optional TEDS (Transducer Electronic Data Sheet), purchased option

All of these parameters are independently controlled in software on a per channel basis.

Note: The functionality of ZonicBook/618E’s dynamic signal conditioning circuitry is also found in the

WBK18 expansion module. Up to six WBK18 modules can be added to a ZonicBook/618E for

channel expansion.

The conditioning circuit includes a built-in programmable voltage excitation source. This source can be

used to stimulate dynamic systems for transfer function measurements, and also serves as a test signal for

the input channels.
