GSM Loopback BER Check
(Option 300 Only)
This test is a functionality check of the Option 300 GSM BER hardware, and does not test any specifications.
The instrument’s RF output is connected to the rear panel 321.4 MHz IF input. The test is made with the RF
signal set to 321.4 MHz at 0 dBm. The instrument is specially configured to emulate a GSM base station
(transmitting BCH then TCH signals for synchronization). A BER measurement is made with an expected
result of 0% error. A second BER measurement is made where known errors are added to the bitstream.
Recommended Equipment
No equipment is required.
