If you just doing hobby project then fine.
In the original posters case it is a University Project and the first card he linked to was a 32 channel 16 bit @ 250Khz (probably for all channels combined) PC104 card, FIFO for data collection accuracy and Programmable Gain amplifier to chnage the ranges on the fly down to +/- 0.625V. Note the input ranges are BIPOLAR as in for negative and positive volatages standard for industrial usage ADCs
4 x D/A outpts 12 or 16 bit, on board FIFOs for data collection accuracy and output waveform pattern at upto 100kHz
Analog inputs and outputs max range is INDUSTRIAL range +/-10V
There are 24 Digitla I/O plus another 4 for Triggers, assumed to be 5V TTL levels.
A counter output assumed 5V TTL levels
RS232 or RS485 Serial port.
Whole board is designed for automotive industry using PC104 (the old PC ISA 16 bit bus) and temperature range of -40 to +85 deg C
Very reminiscent of the ISA 8 and 16 bit bus cards I used to support during the late 1980's and early 1990's
So without specs it is pointless suggesting any cards my basic questions still stand.
