The 2-channel OMB-DBK4
dynamic signal-input card
enables OMB-LOGBOOK
and OMB-DAQBOARD-2000 Series
data acquisition systems to
accommodate inputs from
piezoelectric transducers, such as
accelerometers or microphones, as
well as from various other dynamic
signal sources. Each OMB-DBK4
card is equipped with two BNC
connectors and footprints for two
user-installed Microdot connectors,
permitting it to easily accommodate
most transducer connections.
Architecture
The OMB-DBK4 provides
per-channel, constant current
source outputs, programmable
gain amplifiers, programmable
anti-aliasing filters, and sample
and hold amplifiers.
