1-2 Overview KPCI-3110 and KPCI-3116 User’s Manual
Introduction
This manual is provided for persons needing to understand the installation, interface require-
ments, functions, and operation of the KPCI-3110 and KPCI-3116 boards. These board types
differ in analog I/O resolution, throughput, and D/A filters as shown in
Table 1-1 .
NOTE
Unless noted otherwise, this manual refers to both models collectively
as KPCI-3110.
This manual focuses primarily on describing the KPCI-3110 boards and their capabilities, set-
ting up the boards and their associated software, making typical hookups, and troubleshooting.
There are also sections that discuss calibration and summarize characteristics of DriverLINX
test-panel software.
Features
The KPCI-3110 and KPCI-3116 boards are high-speed, multifunction board types for the PCI
bus. These board types differ in analog I/O resolution, throughput, and D/A filters as shown in
Table 1-1 .
All KPCI-3110 and KPCI-3116 boards share the following major features:
• 32 Single-ended or pseudo-differential analog input channels (refer to), or 16 differential
analog input channels.
•
Programmable bipolar (±10V) and unipolar (0 to 10V) input ranges with gains of 1, 2, 4,
and 8.
• Continuously-paced and triggered scan capability.
•
A 1024-location channel-gain list that supports sampling analog input channels at the same
or different gains in sequential or random order.
• Up to 256 scans per trigger for a total of 262,144 samples per trigger.
•
PCI bus mastering for data transfers.
• Pre-, post-, and about-trigger acquisition modes to acquire data relative to an external event
using computer memory.
•
Internal and external clock sources; one external clock input for the analog input subsystem
and one external clock input for the analog output subsystem.
• Analog threshold triggering using either an external analog input or one of the analog input
channels; a separate DAC sets the trigger level (8-bit resolution, fixed hysteresis).
•
Digital TTL triggering; one external hardware TTL input for the analog input subsystem and
one external hardware TTL input for the analog output subsystem.
• Two analog output channels with a ±10V output range.
•
Simultaneous analog input and analog output operations running at full speed.
• Software calibration of the analog input and output subsystems.
