Gsm/Edge Base Station Bit Error Rate Test [Bert] - Agilent Technologies E4438C Datasheet

Specifications for Signal Personality Characteristics
GSM/EDGE base station bit error
rate test [BERT]
[Option 300]
28
This is a system of two instruments; an ESG with Option 300, and a VSA with
Option 300. Both are required. Option 300 for the ESG requires Option 601 or 602, the
TDMA personalities [Option 402], and the UN7 BER board. The VSA functions as an
IF downconverter. It may be used simultaneously to make transmitter measurements
on the loop back signal.

GSM/EDGE BTS test
E4406A VSA series transmitter tester with Option 202 [GSM and EDGE
measurement personality] and Option 300 [321.4 MHz output].

Pass/fail
BCH signal from the BTS is used to determine TCH
frame and multi-frame location.
The idle frame [no RF] in the TCH signal itself is used to
determine the TCH multi-frame location and so generate
the multi-frame sync signal.
Termination of measurement when error count exceeds
user-specified threshold.
