Introduction
This chapter describes the 6023E, 6024E, and 6025E devices, lists what
you need to get started, gives unpacking instructions, and describes the
optional software and equipment.

Features of the 6023E, 6024E, and 6025E

The 6025E features 16 channels (eight differential) of analog input,
twochannel so f analog output, a 100-pin connector,and 32 linesof digital
I/O. The 6024E features 16 channels of analog input, two channels of
analogoutput, a 68-pin connector an d eight lines of digital I/O. The 6023E
is identical to the 6024E, except that it does not have analog output
channels.
Thesed evicesuse the National Instruments DAQ-STC system timing
controller for time-related functions. The DAQ-STCconsists of three
timinggroups that control analog input, analog output, and general-purpose
counter/timer functions. These groups include a total of seven24-bit and
three 16-bit counters and a maximum timing resolution of 50 ns. The
DAQ-STCmakes possible such applications as buffered pulse generation,
equivalenttime sampling, and seamless changing of the sampling rate.
♦PCI-6023E, PCI-6024E, PCI-6025E, and PXI-6025E only
Withmany DAQ devices, you cannot easily synchronize several
measurementfunctions to a common trigger or timing event. These devices
havethe Real-Time System Integration (RTSI)bus to solve this problem. In
aPCI sy stem, the RTSIbus consists of the National Instruments RTSI bus
interfacean d ar ibbon cable to route timing and trigger signals between
severalfunctions on as many as five DAQ devices in your computer.In a
PXI system, the RTSIbus consists of the National Instruments RTSI bus
interfaceand the PXI trigg er signals on the PXI backplane to route timing
andtrigger signals between several functions on as many as seven DAQ
devicesin your system.
