Errors While Attempting Measurements
5RX PN Offset not set to zero.
For receiver testing, the CDMA Generator is simulating the reverse channel (uplink) signal as it would be sent by a mobile phone. Mobiles transmit on system time, so the PN Offset should be set to zero. Make sure that the field RX PN Offset has an entry of 0.
6CDMA Generator level delivered to the receiver test port of the base station is low.
Verify that the entry for RF Level in the CDMA Generator Menu Selection matches the level intended for receiver (FER) tests. Also, you should check your entry for RX Measurement Path Loss in the Configuration Information Menu. If, in reality, you have much more loss than is indicated in the entry, the RF level at the receiver test port will be much less than is indicated in the CDMA Generator menu screen.
7Incorrect setting for CDMA Generator Mode and/or Data Source.
In the CDMA Generator Menu Selection screen, the Generator Mode should be set to Data and the Data Source should be Random.
