Omega DAQP-208, 208H, 308 user manual Introduction

1. Introduction

DAQP series cards are PCMCIA type II data acquisition adapters with 4 differential or 8 single-ended analog input channels. The number of input channels can be expanded to 128 when used with input expansion cards. DAQP series products include the DAQP-208, the DAQP-208H and the DAQP-308. Card features include:

?Sampling rate up to 100 kHz with 12 or 16 bit resolution

?4 differential or 8 single-ended analog input channels, expandable to 128 channels

?Two 12 bit D/A channels with direct or synchronized update

?Bipolar input range up to ±10 volts with programmable gain of 1, 2, 4 or 8 (DAQP-208/308) or gain of 1, 10, 100 or 1000 (DAQP-208H)

?Programmable scan list with up to 2048 channel and gain entries, plus selectable scan speed of 10, 20 or 40 µs

?Additional 16 bit timer/counter with auto reload, read-out/overflow latches and internal/external gate control and clock sources

?Software, TTL or analog trigger with programmable threshold and pre-trigger capability

Equipped with a 4K data FIFO, the DAQP card can achieve high speed data acquisition under various operating platforms. Also equipped with a 2048 entry scan FIFO, the DAQP supports full speed, random order channel scanning and gain selection for all input channels including expansion channels.

The DAQP card uses a 24-bit pacer clock and a programmable divide-by-2, by-10 or by-100 pre-scaler. The pacer clock can be used with either an internal or external clock source. DAQP series cards are also equipped with two independent 12 bit D/A output channels with a bipolar range of -5 to +5 volts. D/A channels can be updated directly when writing the corresponding D/A port (direct mode) or simultaneously with a synchronization signal.
