What Are WaveBooks?

WaveBooks are high-speed portable data acquisition devices that can be used in a variety of applications,

such as testing engine strain, multi-channel acoustics, mechanical integrity, and vibration/shock/strain.

WaveBook models that are discussed in this manual have the following features, with exceptions as noted:

Power Options: Power can be supplied from an AC-to-DC adapter, battery, DBK30A rechargeable

battery module, DBK34, or DBK34A uninterruptible power supply modules.

Easy Connection to Notebook or Desktop PCs.

Analog Input Channels: BNC connectors keep input signals isolated from the chassis and commons.

16 High-Speed Digital Inputs

Digital Signal Processing (DSP): Allows you to define a channel scan-sequence and associated gains

across all channels. Also provides for real-time digital calibration on a per-sample basis.

Programmable Scan Sequencing: A 128-location scan sequencer allows you to program the analog

channel scan sequence, the associated unipolar/bipolar A/D range, and the input amplifier gain.

WaveBook performs 1 MHz scanning and gain switching over both its built-in and expansion

channels.

Single, or Multi-Channel Triggering

Pre- and Post-Trigger Readings

Digital-Pattern Trigger: A trigger occurs when a Digital I/O pattern is equal to, not-equal to, greater

than, or less than a user-defined 16-bit digital pattern. This is useful when trying to capture noise,

vibrations or some other physical disturbance that occurs at a particular point in a digitally-sequenced

process, such as a relay-logic-control system. Trigger latency of the digital pattern trigger is less than

200 ns for post-trigger acquisitions.

Pulse Trigger: Enables triggering and the correlation of lower-speed waveforms with the occurrence

of a user-defined, high-speed pulse.

20 kHz Low Pass Filters: When a PGA option is installed, eight low pass anti-alias filters are

available, one for each channel.

External Clock Input: The external clock is useful when data collection depends on rotational speed

or axial position. Note that the external clock’s input can be set to a slower rate.

Synchronization: The “A” and “E” Series WaveBooks include a synchronizing feature that allows

multiple WaveBook/516As, WaveBook/512As, and WaveBook/516E units to operate in sync.

WaveBook/516E only: Includes a 10/100BaseT Ethernet connection port, which allows for a

continuous stream of data to be collected and stored in a PC.

WaveBook/516E only: Includes 3 expansion ports for expanding the acquisition system via the built-

in parallel port interfaces of up to three other devices. For example, a WaveBook/516A could be

attached to WaveBook/516E’s Expansion Port 1, a WaveBook/512A could be attached to Expansion

Port 2, and a WBK40 Thermocouple Module could be attached to Expansion Port 3.
