1 Introduction
1.1 Product Overview
The DM35418 is a software configurable high-speed, 18-bit data acquisition module in the PCIe/104 format. This module provides 8 differential
or single-ended analog input channels, with programmable gain and input ranges. This module is capable of either independent or simultaneous
sampling. The DM35418 also features eight 16-bit high-speed analog outputs with programmable output ranges, and a 32-bit port of digital I/O,
and synchronization of multiple boards with the SyncBus.
The DM35218 is a software configurable high-speed, 18-bit data acquisition module in the PCIe/104 format. This module provides 4 differential
or single-ended analog input channels, with programmable gain and input ranges. This module is capable of either independent or simultaneous
sampling. The DM35218 also features four 16-bit high-speed analog outputs with programmable output ranges, and a 32-bit port of digital I/O,
and synchronization of multiple boards with the SyncBus.
