However, an overrange event does not stop the acquisition process or change the data, providing the user with full control over the disposition of data. In addition to front panel indicators, an overrange condition is also detectable by requesting status via software at the end of an acquisition. IEPE Fault Detection. IEPE fault detection is also provided, with a front-panel LED indicator for each channel. This hardware detection monitors for an open as well as a shorted transducer connection. Because it is continuously monitored during an acquisition, even intermittent faults are detected and latched. As with overrange detection, detection of this error condition does not alter the acquisition process or its data, and fault status is available via software at the end of an acquisition. TEDS Support. TEDS, Transducer Electronic Data Sheet, is a sensor feature referring to the storage of calibration information within the sensor. The WBK18 can read calibration information from TEDS-compatible sensors and automatically scale the readings from each sensor using the acquired calibration information. TEDS support is a software option for the WBK18, and can be easily added after the initial purchase. Excitation Source. The WBK18's AC excitation source is a sine wave-based voltage source that is programmable in frequency from 1 Hz to 5 kHz and in amplitude from 100 mVp-p to 10 Vp-p. Continuous sine and Sweep sine modes are available. It can be used as a test source for the input channels or as excitation for other system elements, such as the amplifier for a shaker table. All of its parameters are software controlled, and its output is conveniently provided on a front panel BNC connection. | | Low-Pass Filter (software programmable per channel) Type: 8-pole Butterworth with simultaneous sample- and-hold (SSH) Cutoff Frequency (Fc): 10 Hz to 50 kHz in 1-2-5 progression Alias Rejection: 75 dB min Channel-to-Channel Phase Matching*: 1' typ, 2' max Unit-to-Unit Phase Matching*: 1' typ, 2' max SSH latency: 100 ns max Amplitude Accuracy**: ±0.5 dB (Fin < Fc/2) Total Harmonic Distortion: -70 dB typ IEPE Bias Source: 4 mA, 24V compliance (on/off software programmable per channel) IEPE Fault Detection Thresholds: <1V (short), >25V (open) IEPE Fault Indication: Front panel LED per channel, software status Excitation Source Channels: 1 Signal Connection: BNC Frequency Range: 1 Hz to 5 kHz Frequency Resolution: 0.01 Hz Amplitude Settings (p-p): 10V, 5V, 2V, 1V, 500 mV, 200 mV, 100 mV, 50 mV Waveform Modes: Continuous sine, Sweep sine Output Impedance: 50 Ohm Accuracy: ±0.1 dB Ordering Information Description Part No. 8-channel dynamic signal conditioning module for the ZonicBook/618E WBK18 | | |
