A/D, D/A- based Test System
This section describes a practical test system that can perform both transmit and receive performance verification.
Hardware Description
The test system should have the following components.
• Data acquisition hardware
• Test interface board
Data Acquisition Hardware
• A 12-bit A/D channel with a throughput of at least 1 Ms/s that is configured for single ended reference and
±10V range
• A 12-bit D/A channel with a throughput of at least 1Ms/s that is configured for ±10V range
• Data acquisition channels that have an external trigger capability
National Instruments multi-function cards, such as PXI-6070E or PCI-MIO-16E-1, are examples of data acquisition
hardware that meet the requirements for the test system.
Test Interface Board
A custom interface board needs to be designed that provides 70dB attenuation, a ~5 ohm load, a coupling circuit, and a
peak detector circuit that triggers on the UUT transmitted packets. Figure D.1 is a diagram of circuitry that provides the
required interface functions.
