1-2 Overview KPCI-3101 — KPCI-3104 Series User’s Manual
Features
The KPCI-3101–4 Series is a family of low-cost, multifunction data acquisition boards for the
PCI bus. The KPCI-3101–4 Series consists of the following boards: KPCI-3101, KPCI-3102,
KPCI-3103, and KPCI-3104. These board types differ in analog I/O resolution, analog input
sample frequency, analog input ranges, and the number of analog output channels, as shown in
Table 1-1 .
All KPCI-3101–4 Series boards share the following major features:
• PCI bus mastering capability for analog inputs
•
16 single-ended or pseudo-differential analog input channels, or 8 differential analog input
channels (for information on pseudo-differential analog input channels, see
“Connecting
pseudo-differential voltage inputs” in Section 3 )
• Signal conditioning through connections to 5B Series backplanes
•
Input 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 in triggered scan mode
•
Internal and external clock sources for the analog input subsystem
• Digital TTL triggering for the analog input subsystem
•
Software calibration of the analog I/O circuitry
• Two 8-bit digital ports programmable as inputs or outputs on a per-port basis; digital input
lines from these lines can be included as part of the analog input channel-gain list to corre-
late the timing of analog and digital events; digital outputs can drive external solid-state
relays
•
One 7-bit digital I/O port programmable as a general-purpose (non-clocked) input or output
port
• Four user counter/timers programmable for event counting, frequency measurement, rate
generation (continuous pulse output), one-shot pulse output, and repetitive one-shot pulse
output
•
Programmable gate types
• Programmable pulse output polarities (output types) and duty cycles
For a discussion of these features in detail, refer to Section 2 .
