Bit Error Rate Test (BERT)
(ESG-D series only)
(Option 300 requires Option UN8 revision C or better.
Option UNA is highly recommended. The following are required:
GSM BTS test only
E4406A VSA-series transmitter tester with Options BAH (EDGE
measurement personality) and 300 Rev. A (321.4 MHz output).
GSM/EDGE BTS test
E4406A VSA-series transmitter tester with Option 202 (GSM
and EDGE measurement personality) and Option 300 Rev. B (321.4
MHz output). ESG firmware Option 202, EDGE personality, is also
required. To upgrade from Option 300 Rev. A to Option 300 Rev. B
requires new hardware.
See configuration guide for a bundled ordering convenience.

BCH signal from the BTS is used
to determine TCH frame and
multiframe location.
Termination of measurement
when error count exceeds user
specified threshold.
