Key Features of the DT9837

Figure 1 shows the layout of the DT9837 module.
The key features of the DT9837 module are as follows:
• Simultaneous analog input and waveform analog output operations
• Analog input subsystem:
− Four, simultaneous 24-bit A/D converters
− Throughput rate up to 52.734 kSamples/s for simultaneous, high-resolution
measurements
− Input range of ±10 V with software-selectable gains of 1 and 10 for an effective input
range of ±10 V and ±1 V
− Support for IEPE (Integrated Electronic Piezoelectric) inputs, including use of a 4 mA
current source and AC or DC coupling
− The ability to return the value of tachometer counter 0 in the analog input data stream,
allowing you to measure the period or frequency of the tachometer input signal
synchronously with analog input measurements
− Supports a start trigger for acquiring pre-trigger samples and a reference trigger for
acquiring post-trigger samples. You can specify the number of post-trigger samples to
acquire before stopping the operation.
− For the start trigger, supports a software-programmable trigger source (software,
external digital trigger, or a positive-going analog threshold trigger on analog input
channel 0). The threshold level is fixed at 1.0 V for the analog threshold trigger.
