1.1 Introduction
The PCI-1713 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 samples/s, 12-bit resolution and isolation protection of 2500
V
DC
.
PCI-bus Plug and Play
The PCI-1713 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
assignment, are automatically controlled by software.
Flexible Input Types and Range Settings
The PCI-1713 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 configurations 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-1713 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
generates 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 S/W, Internal and External Pacer
Triggering
The PCI-1713 supports three kinds of trigger modes for A/D conver-
sion: software triggering, internal pacer triggering and external pacer
triggering. The software trigger allows users to acquire a sample when
it is needed; the internal pacer triggers continuous high-speed data
acquisition. The PCI-1713 also accepts external trigger sources,
allowing synchronous sampling with external devices.
