Board Initialization

To use the DMM-16-AT board in an appllication using the UD, the dscInitBoard function should use the board macro DSC_DMM16. This is shown in the example below...

dscInitBoard ( DSC_DMM16 , &dsccb, &board );

Analog Input

Max Input Channels: 16 (single-ended) or 8 (differential)
A/D Resolution: 16 bits (1/65536 of full-scale)
Data range: -32768 to +32767 for all voltage ranges
Input Ranges (Bipolar): ±10V, ±5V, ±2.5V, or ±1.25V
Input Ranges (Unipolar): 0-10V, 0-5V, or 0-2.5V
Supported Conversion Triggers: Software, Internal Clock, or External TTL Signal
Maximum Conversion Rate (Software Command): 2,000 (approx.) samples per second
Maximum Conversion Rate (Interrupt Routine w/FIFO): 100,000 samples per second
FIFO: 512 samples with fixed threshold of 256

This board supports the following programmable input ranges and resolutions:

A/D Ranges
