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].
Test technique RF loopback
Supported systems
GSM 400
GSM 850
GSM 900 [P-GSM]
DCS 1800
PCS 1900
E-GSM [extended]
Minimum power level –136 dBm [ESG minimum]
Maximum power level +13 dBm [option dependent]
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.
