产品详情
参数
包装
  • Offers a Per-Channel Programmable Gain Amplifier for ±50 mV,±500 mV, or ±5 V FS Input
  • Includes a Built-In Current Source for ICP Transducer Biasing
  • Offers Per-Channel Anti-Aliasing Filters
  • Provides Per-Channel Simultaneous Sample and Hold
  • Accommodates Either AC or DC Coupled Signals
  • Both Dynamic Analog Inputs Sampled Within 50 ns of Each Other

  • The 2-channel OMB-DBK4dynamic signal-input cardenables OMB-LOGBOOKand OMB-DAQBOARD-2000 Seriesdata acquisition systems toaccommodate inputs frompiezoelectric transducers, such asaccelerometers or microphones, aswell as from various other dynamicsignal sources. Each OMB-DBK4card is equipped with two BNCconnectors and footprints for twouser-installed Microdot connectors,permitting it to easily accommodatemost transducer connections.

    Architecture
    The OMB-DBK4 providesper-channel, constant currentsource outputs, programmablegain amplifiers, programmableanti-aliasing filters, and sampleand hold amplifiers.
