MCC DT9857E-16-xAO 16 Channel Speed Dynamic Signal Analyzers
MCC DT9857E-16-xAO
16 Channel Dynamic Signal Analyzers
The Measurement Computing DT9857E-8-xAO and DT9857E-16-xAO are USB-based, high-speed dynamic signal analyzers with 8 or 16 simultaneous 24-bit IEPE sensor inputs, up to 105.4 kS/s/ch sample rate, one tachometer input, and 16 digital I/O. They feature built-in IEPE signal conditioning for direct measurements from sensors like accelerometers and microphones.
The DT9857E Series are high accuracy dynamic signal acquisition devices for noise, vibration, and acoustic measurements. Eight or sixteen, 24-bit, IEPE sensor inputs are synchronized with a tachometer input, two measurement counters, and a general purpose counter/timer to provide data streams that are matched in time, for field or laboratory use. An 8-bit digital output port is available for control.
The DT9857E-8-xAO module provides eight analog input channels and the DT9857E-16-xAO module provides 16 analog input channels. IEPE sensors can be connected to these BNC inputs. Software-selectable gains of 1 and 10 provide effective input ranges of ±10V and ±1 V. Each analog input channel uses a 24-bit Delta-Sigma analog-to-digital converter (ADC) that provides anti-aliasing filtering based on the clock rate. In addition to acquiring data from the analog input channels, the DT9857E supports the ability to simultaneously acquire the value of the tachometer input, general-purpose counter/timer, measure counters, and digital input port in the analog input stream, allowing precise correlation of all input signals.
Applications that require accelerometer, vibration, noise, or sonar measurements often use IEPE sensors. IEPE conditioning is built-in to the analog input circuitry of the DT9857E module. Each analog input channel provides the following capabilities for IEPE support:
Excitation current source — Internal excitation current source of 4 mA
Coupling type — Software-programmable AC coupling or DC coupling
Compliance voltage — +24 V
The DT9857E Series supports an internal A/D clock, which is derived from the 48 MHz crystal oscillation. Users can program the sampling frequency at which to pace the input operations. The sampling frequency ranges from 195.3125 Hz to 105.469 kHz.
The DT9857E Series supports a tachometer input signal with a range of ±30 V. The frequency or period between two edges of the tachometer input signal can be measured to calculate the rotational speed of the high level tachometer input. The value can then be returned the value in the analog input data stream. The starting edge (either rising or falling) of the tachometer signal is programmable. An internal 12 MHz counter is used for the measurement.
The DT9857E Series supports a 32-bit, general-purpose, counter/timer. The value of the counter/timer can be returned in the analog input data stream, if desired. The following counter/timer functions are supported: event counting, edge-to-edge measurement, continuous edge-to-edge measurement (for determining the frequency and period width of a signal), continuous pulse output, one-shot, repetitive one-shot, and up/down counting operations. Programmable gates, clocks, and output signals are also supported.
The DT9857E Series supports one digital input port, consisting of 8 digital input lines and one digital output port, consisting of 8 digital output lines.
