Audio Processor ESP-00 II Standard Version Chassis
Test Description
This procedure will cover the ControlSpace
used for the ESP-88, 88C and ESP-00 chassis.
This procedure will provide a step-by-step process to performing a product hardware validation
test on analog audio quality at varying power levels, digital audio quality, and throughput. It is
the focus of this procedure to test the ESP-xx base system only. A known good 4x4 Mic/Line
card is used as part of the test setup to provide audio input and output paths.
• The analog portion of this test will utilize an analog audio generator as input to the device under
test (DUT) and an audio analyzer to provide the data recovery and test results.
•
The test operator will be required to manually switch the input and outputs of the test signals
and adjust the varying gain levels and frequencies used to exercise the product.
• The digital portion of the hardware will be tested by directing the analog input signals through
the Digital Signal Processor (DSP) and back through to the analog output. This will effectively
test the ESP Backplane.
IMPORTANT NOTE: The setup detailed in this document is the recommended method of test
and should be followed where equipment availability allows.
This document may be used as a guide to performing the validation tests where some equip-
ment may be absent. The basic steps may be derived from the steps detailed in this document
with some variation required dependent on the type of equipment available.
