MCC DT9837A Dynamic Signal Analyzers
MCC DT9837A
Dynamic Signal Analyzers
The Measurement Computing DT9837A and DT9837B are USB-based dynamic signal analyzers with four simultaneous 24-bit IEPE sensor inputs, and one tachometer input.
The DT9837A features a 52.7 kS/s/ch sample rate, while the DT9837B offers sample rates up to 105.4 kS/s/ch. The DT9837B also includes one 24-bit analog output.
Both devices feature built-in IEPE signal conditioning for direct measurements from sensors like accelerometers and microphones.
Each device supports four, single-ended analog input channels. All analog input channels are simultaneously clocked. Software-selectable gains of 1 and 10 provide effective input ranges of ±10 V and ±1 V, respectively. The DT9837A uses a 24-bit Delta-Sigma analog-to-digital converter (ADC) that provides anti-aliasing filters based on the clock rate. These filters remove aliasing, which is a condition where high frequency input components erroneously appear as lower frequencies after sampling.
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 DT9837A.
These devices support an internal clock, which is derived from the USB clock. Use software to specify the internal clock source and the frequency at which to pace the input and output operations and to start the sample clock. The sampling frequency ranges from 195.3 Hz to 52.734 kHz.
Each device accepts one ±30 V, 32-bit tachometer input signal. This signal has a maximum frequency of 1 MHz and a minimum pulse width of 0.4 μs. The threshold voltage is fixed at +2 V with 0.5 V of hysteresis. Users can measure the frequency or period of the tachometer input signal using tachometer counter 0. Users can also measure the phase of the tachometer input signal in relation to the A/D sample using tachometer counter 1.
The DT9837A supports one 24-bit analog output channel. The DT9837A provides a two-pole, 10 kHz Butterworth filter to prevent noise from interfering with the output signal. The analog output channel powers up to a value of 0 V ±10 mV. The device can output bipolar output signals in the range of ±10 V, with a gain of 1. The output clock on the DT9837A is derived from the USB clock to produce the output clock frequency.
