Key Features - Details
Spurious emission detection
- Apply the patented spurious emission positioning algorithm/zone its location
- Single-tone spurious emission and broadband noise measurement/discrimination
- In-band noise separation/report by utilizing OFDM signal characteristics
Inspection variable measurement for RF stations
- Periodic inspection of RF interference in the RF stations (BTS/repeaters) for efficient management of RF resources
- Automatic measurement of inspection variables (total power, channel power, ACLR, OBW, SEM ) in the RF stations according to the operator setting
