PCI-1713U User Manual 2
Chapter 1 Overview
1.1 Introduction
The PCI-1713U is a 12-bit 32-channel analog input card for the PCI bus.
It provides 32 analog input channels with a sampling rate up to 100k sam-
ples/s, 12-bit resolution and isolation protection of 2500 VDC.
PCI-bus Plug and Play
The PCI-1713U uses a PCI controller to interface the card with the PCI
bus. The controller fully implements the PCI bus specification Rev 2.1.
All bus relative configurations, such as base address and interrupt assign-
ment, are automatically controlled by software.
Flexible Input Types and Range Settings
The PCI-1713U features an automatic channel/gain scanning circuit. The
circuit, rather than your software, controls multiplexer switching during
sampling. The on-board SRAM stores different gain values and configu-
rations for each channel. This design lets you perform multi-channel
sampling with different gains for each channel and with free combination
of single-ended and differential inputs.
High-speed Data Acquisition
The PCI-1713U provides a sampling rate up to 100k samples/s. It has an
on-board FIFO buffer, which can store up to 4K A/D samples and gener-
ates an interrupt signal when the FIFO is half full. This feature provides
continuous high-speed data transfer and more predictable performance on
Windows systems.
Supports Software, Internal and External Pacer Triggering
The PCI-1713U supports three kinds of trigger modes for A/D conver-
sion: software triggering, internal pacer triggering and external pacer trig-
gering. The software trigger allows users to acquire a sample when it is
needed; the internal pacer triggers continuous high-speed data acquisi-
tion. The PCI-1713U also accepts external trigger sources, allowing syn-
chronous sampling with external devices.
