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.
