Suggested Testing Equipment - Sierra Wireless MC5725 Hardware Integration Manual

Rev 1.9.1 Feb.09
In the event of a discrepancy in values between this guide and the Product Specification Document (PSD), the PSD takes precedence.
specified receiver sensitivity of ‐104 dBm. The objective
of this test is to determine if the FER measured is within
the acceptable limits for the specified receiver sensitivity
of the module. Unlike the FER tests performed during
production testing, this test determines the receiver
performance without the influence of the noise factor
(AWGN), but with extremely low cell power. The
reported FER and the confidence level must be <1% and
>95% respectively for the test to be considered a pass.

RF sensitivity testing: BER / BLER for different bands
·
and modes
· Transmitter and receiver tests (based on relevant sections
of the 3GPP TS51010 and 3GPP 34121 documents)

Suggested testing equipment

To perform production and post‐production tests, you require
appropriate testing equipment.
Figure 8‐2 shows a suggested test station for use with devices
incorporating either the MC57xx or the MC87xx.
In the test station as shown, a test computer coordinates
testing between the host device with an integrated module and
the measurement equipment. If the test computer does not
have direct access to the module, then the host device must
have custom software to forward instructions from the test
computer to the module.
This suggested station setup includes:
Audio analyzer—to evaluate Tx
•
• Power meter—to evaluate current consumption for Tx and
Rx in various modes
• Signal generator—to evaluate Rx
When using this setup, you can allow the signal generator to
run continuously throughout the production testing
procedure.
