Description
The WBK16 is an 8-channel strain-gage signal-conditioning module for the WaveBook system. Up to
eight of these modules (64 channels) can be accommodated by a WaveBook and scanned at 1 µs/channel.
Almost all bridge configurations are supported via a bridge-completion network and software. High-gain
differential-amplifier applications are also supported. Software controls bridge configuration, gain, offset,
excitation voltage, polarity, filtering, and the calibration process.
Refer to the following block diagram as needed while reading this section.
