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.

Test technique

RF loopback

Supported systems

GSM 400

GSM 850

GSM 900 (P-GSM)

DCS 1800

PCS 1900

E-GSM (extended)

Minimum power level

Maximum power level

Power level accuracy

Relative power level

Threshold

–136 dBm (ESG minimum)

+13 dBm (ESG maximum)

±0.5 dB (23° ± 50 °C)

0 to ±130 dB relative to timeslot under test. (Limited only by output power range of the ESG. Based on Option UNA specification.)

Timeslot under test timeslots tested 0 to 7

A single timeslot is tested at one time. (No frequency hopping.)

Encryption None

Measurement triggers Immediate, trigger key, bus, external

Measurement indication

BCH sync

Pass/fail

BCH signal from the BTS is used to determine TCH frame and multiframe location.

Termination of measurement when error count exceeds user specified threshold.
