Frequently Asked Questions

(1)

 

Topic:  Environmental Factors

Question:  What Environments are WaveBook Systems Intended for?

Answer:    WaveBook Systems are designed to operate within 0° to 50°C  ( 32° to 122°F) and with a

relative humidity of up to 95%RH, non-condensing.  The products can be stored at temperatures
within the range of -20° to +70°C  (-40° to 158°F).  WaveBook systems should always be
protected from snow, rain, extreme dust, and harsh sun.

(

2) Topic:  32-Bit API Support, DaqX

Question:   I am writing my own application that interfaces to the WaveBook.  Is the 32-bit enhanced mode

support for Windows 95, Windows 98 and Windows NT available?

Answer:

Yes, the current version of the DaqX software supports 32 bit enhanced mode programming.

Question:  What is DaqX software?

Answer: 

DaqX software is low-level software support for application development. DaqX is installed
during the installation of the WaveView application.  DaqX supports Visual C++, Visual Basic,
and Delphi programming environments.

Question: Where can I get the latest version of WaveView/DaqX software?

Answer:

You can download the latest versions from our website.  This service is free.

(3)  Topic:  WBK14 - Dynamic Signal Conditioning Module

Question:   Why can't I use the external clock feature on the WBK14 to control my acquisition speed?

Answer:

The external clock on the WBK14 is used to dynamically move the corner frequency of the
filter, not pace the A/D in the WaveBook.  This feature is often required in vibration
applications where the filter is moved as the device under test is vibrated (or excited) at varying
frequencies. Unlike the WaveBook/516 that has a special input for clocking the A-to-D, the
WaveBook/512 has no provisions to do so.

Question:  Is there anything special I should know about WBK14’s power-up state?

Answer:

At power-up the current output of the WBK14 is open circuited.  It is only after being
programmed that the current source is engaged.

Question:  In regard to attenuation, what is the filter roll-off for the WBK14 filter?

Answer:

The WBK14's Butterworth filter is down 3 dB at the corner frequency. Beyond that point, the
signal attenuates at 48 dB per octave or 160 dB per decade. This is a substantial amount of
attenuation for most applications.
