Agilent Technologies E4438C manual GSM/EDGE base station bit error rate test BERT

Specifications for Signal Personality Characteristics

GSM/EDGE base station bit error rate test [BERT]

[Option 300]

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 BTS test only

E4406A VSA series transmitter tester with Options BAH

[GSM measurement personality] and Option 300 [321.4 MHz output].

GSM/EDGE BTS test

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

Power level accuracy	±0.5 dB [23° ± 5 °C] [power and frequency dependent]
Relative power level	0 to ±130 dB relative to timeslot under test.
	[Limited only by output power range of the ESG.]
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, external, remote
	[LAN, GPIB, RS-232]
Measurement indication	Pass/fail
BCH sync	BCH signal from the BTS is used to determine TCH
	frame and multi-frame location.
TCH sync	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.
Threshold	Termination of measurement when error count exceeds
	user-specified threshold.
