4.2 BER test
Purpose:
This test verifies the BER value of Transmitter/Receiver UUT meet
Specification.
Instrument
Shield Box: ETS 5240-24
Attenuator: ATM AF085-30
AMIMON patch antenna
Test Methodology
During this test sequence a WHDI link is established (regist
authentication). The audio signal is analyzing by audio analyzer in
baseband chip. The attenuated RF cables connecting the two chambers
are calibrated to emulate a 20m link. The following sequence is applied
through Sparrow RX UART interface.
1. Switch TX power ON
2. Switch RX power ON
3. TX
– Set VGA level to 60dBm (frequency is selected automatically
through a AFS mechanism)
4. Link registration. Allow 10 seconds for completion.
5. Generate audio
test pattern through the Laptop’s HDMI port.
6. Hear
30’s audio signal from the TV or speaker.
7. Calculate Bit Error Rate for 30
’s audio analyzer, and compare with test
limits.
Criteria
BER ≤ 10
-4
Block Error Rate = 0
