Test To Be Performed
Transmit average phase error (RMS) at max and min power
Transmit average phase error (Peak) at max and min power
Transmit average frequency error at max and min power
Transmit power error at level 7 (29 dBm) on CH62
Transmit power error at level 10 (23 dBm) on CH62
Transmit power error at level 15 (13 dBm) on CH62
Transmit power error at max and min power on CH1
Transmit power error at max and min power on CH124
Transmit burst time mask at max and min power
Receive Bit Error Test for RES II (at -102 dBm)
Receive Frame Erasure Rate for RES II (at -102 dBm)
Received level (RX_LEV) indication at -100 dBm
Received level (RX_LEV) indication at -45 dBm
Received quality (RX_QUAL) indication for RX_LEV tests
Note: The transmit average test values should be derived from 10 separate readings.
The receive signal strength for transmit measurements should be -85 dBm.
The receive test values should be derived from the reception of 20K bits of data.
