Si4822/26/27/40/44-DEMO BOARD TEST PROCEDURE
1. Introduction
The purpose of this document is to describe the test procedures used in Silicon Laboratories for the Si4822/26/27/
40/44-DEMO AM/FM/SW tuner board. It is also intended to enable customers to exactly replicate Silicon
Laboratories’ test environment so that variances in customers’ and Silicon Laboratories’ measured results can be
accurately compared. This document covers FM, AM, and SW tests for the Si4822/40 and Si4826/27/44 receiver.
The Si4822/26/27/40/44-DEMO board provides a platform to test and operate the Si4822/26/27/40/44 tuner. Refer
to the Si4822/26/27/40/44-DEMO Board User’s Guide for the operation details of the demo board.
