Using DBK Cards and Modules for Signal Conditioning
The DBK signal-conditioning cards and modules are designed for use with DaqLab, DaqScan,
DaqBook, LogBook, and various data acquisition boards, i.e., ISA, PCI, and compact-PCI
types. The DBKs perform best when used with an acquisition device that can dynamically
select channel, gain, and range. DBK cards and modules with dynamic channel and
gain/range selection allow for high channel-to-channel scan rates with a variety of
transducers.
Note: Only passive DBKs, such as the DBK1 BNC module, the DBK11A screw terminal card,
and the DBK40 BNC analog interface, can be used with Daq PC-Cards.
DBK output signals can be bipolar, e.g., -5 to +5 V, or unipolar, e.g., 0 to 10 V. The user can
select a range of relevant values to correspond to the lowest signal (e.g., -5 or 0 V) and the
highest signal (e.g., 5 or 10 V) signal. This type of range selection guarantees the highest
resolution in 12-bit or 16-bit conversion.
DBK modules share the same footprint as the DaqBook and a typical notebook PCs; allowing
for convenient stacking. The majority of these modules have their own power supply;
however, several options exist for packaging and powering the DBKs.
Reference Note:
DBK options are detailed in the DBK Option Cards and Modules User’s Manual
(p/n 457-0905). As a part of product support, this manual is automatically loaded
onto your hard drive during software installation. The default location is the
Programs directory, which can be accessed through the Windows Desktop
