1.0 SPIO-4 System Overview
The SPIO-4 is one of several National Semiconductor digital controller/capture boards that are used by
multiple evaluation systems. The objective of these software/hardware evaluation systems is to allow our
customers to easily and accurately evaluate National’s signal-path devices in a lab setting. At the time of
SPIO-4’s release, two different evaluation system software (GUIs) make use of this board: the
WaveVision-5 and the Sensor AFE. The board ships with the current version of the WaveVision-5
software.
In addition to the controller/capture board (i.e., the SPIO-4) and the evaluation GUI software (e.g.,
WaveVision-5 or Sensor AFE), the third essential element of an evaluation system is the device or signal-
path evaluation board that plugs into the controller board. This eval board is generically referred to as the
“DUT board”. Each DUT board comes with its own Users’ Guide which documents its specific features.
Each DUT board also comes with some software that the user must install before using it. In the case of
the WaveVision-5 GUI, this software is essentially a device-specific module that adds support for the
future device eval boards. In the case of Sensor AFE device family, the eval board comes with a
complete, custom Sensor AFE that is specifically paired with that device.
The WaveVision-5 and Sensor AFE GUI software have their own Users’ Guide documents that describe
how to interact with the GUI.
This User’s Guide describes only the SPIO-4 board. The user is expected to refer to this guide only if
necessary. The DUT Users’ Guide and the GUI Users’ Guide are the primary documents that describe
how to work with a National signal-path evaluation board.

1.1 SPIO-4 System Features
1.2 Packing List
The SPIO-4 kit (National order number SPIO-4/NOPB ) consists of the following components:










Captures or sources multiple signal-path data streams and transfers them to/from the PC based
application software through a USB 2.0 connection (USB1.1 compatible).
Supports jumper-less, plug-and-play configuration. The GUI automatically discovers the attached
DUT board and loads the appropriate software module for it.
Supports a wide variety of signal-path evaluation board through a standardized connector (GPSI-
16/GPSI-32).
Capable of storing up to 8MBytes of signal-path data.
DUT interface can be SPI, I2C or parallel.
Powered either by PC via USB or external supply.
