3. TESTING PROCEDURE
All information required to perform the desired tests and measurements should be obtained from the communication analyser’s
user manual.
Ensure that the unit being tested is capable of both initiating a call to the analyser, and receiving a call from the analyser.
Confirm that the displayed Temporary Mobile Subscriber Identity (TMSI), International Mobile Equipment Identity (IMEI),
and dialled number are correct.
When a call is in progress the following tests should be carried out on channels 1, 62 and
124 . The recorded results must be within the acceptable stated limits, if the unit being tested passes all the tests it should be
taken as functioning correctly. If the unit being tested fails to conform with any of the expected measurements, it should be
taken as faulty and repaired accordingly. The following table states the required tests and tolerances.
TEST TO BE PERFORMED LOWER LIMIT UPPER LIMIT
Transmit average phase error (RMS) at peak power 5
Transmit average phase error (Peak) at peak power 20
Transmit average frequency error at peak power -90 Hz +90 Hz
Transmit power error at level 5 (33 dBm) -2 dB +2 dB
Transmit power error at level 7 (29 dBm) -2 dB +2 dB
Transmit power error at level 10 (23 dBm) -3 dB +3 dB
Transmit power error at level 15 (13 dBm) -3 dB +3 dB
Transmit amplitude negative peak flatness -1 dB
Transmit amplitude positive peak flatness +1 dB
Transmit amplitude envelope at -28 us -70 dB
Transmit amplitude envelope at -18 us -30 dB
Transmit amplitude envelope at -10 us -6 dB
Transmit amplitude envelope at 556 us -6 dB
Transmit amplitude envelope at 564 us -30 dB
Transmit amplitude envelope at 574 us -70 dB
Receive Bit Error Test for Class II Residual (at -102 dBm) 4 2%
Receive Frame Erasure Rate for RES II (at -102 dBm) 4 0.12%
Note: 1. The transmit average test values should be derived from 10 separate readings.
2. The receive signal strength for transmit measurements should be -85 dBm.
3. The receive test values should be derived from the reception of 20K bits of data.
4. There is approximately 1.8dB loss between the antenna port and the RF SMA connector on the test adaptor. The test
specifications are written for the power levels AT THE ANTENNA.
