    NI-9236 Getting Started Connecting a Quarter-Bridge Sensor You can connect quarter-bridge sensors to the NI-9236. You must connect each EXC terminal to only one strain gage to maintain the channel-to-channel crosstalk performance of the module. For the best system accuracy, observe the following conditions when connecting to the NI-9236.

    NI-9236 Getting Started Each channel on the NI-9236 has an independent 24-bit ADC and input ■ amplifier that enables you to sample signals from all eight channels simultaneously. The NI-9236 is isolated from earth ground. However, the individual channels ■...
  • Page 8 Filtering The NI-9236 uses a combination of analog and digital filtering to provide an accurate representation of in-band signals and reject out-of-band signals. The filters discriminate between signals based on the frequency range, or bandwidth, of the signal.
