32-Channel Accel Input Card (GN3210)

In differential mode, the card can be used in electrically noisy environments. The CMRR of the true differential amplifiers ensures high signal fidelity.
When using the passive voltage probe and/or the current clamp options, the card can be used as an entry-level electrical-input amplifier to measure high voltages and currents. Calibrating the probes and clamps with the channels and storing calibration results in the Perception Sensor Database can increase the accuracy well above the accuracy rating of the probe or clamp.
In single-ended mode, the card can serve as a cost effective input for preconditioned signals to be recorded with the GEN DAQ series of products.
In IEPE mode, the card offers excellent price/ performance ratio for an array of IEPE based sensors (accelerometers, microphones, etc.). The high dynamic range of the amplifier and the 24 bit A/D converter as well as the excellent band-pass flatness up to a 100 kHz bandwidth ensure phase alignment and accurate amplitude measurements.
In Charge mode, the card can be used directly with charge type sensors, such as piezoelectric accelerometers or pressure transducers.
