Using the Spectrum Analyzer
Use the Spectrum Analyzer in direct connect mode to:
Use the Spectrum Analyzer in Over Air mode to:
- Verify that your transmitted signal does not interfere (produce spurs and harmonics) with other signals.
- Verify spectral integrity-look at a signal to see if it meets expectations, look for unwanted signals.
CAUTION: The maximum power for the RF In (Port 1) and RF Out/SWR (Port 2) ports is +20 dBm (100 mW). When using the 8481A/8482A Power Sensors, the maximum input power applied to the Power Sensor is +24 dBm (300 mW). When using the 8481D Power Sensor, the maximum input power is +20 dBm (100 mW). When directly coupled to a base station (BTS) or Access Network (AN), the test set can be damaged by excessive power applied to any of these three ports.
To prevent damage in most situations when you directly couple the test set to a base station, use the high power attenuator between the test set and the BTS.
NOTE: The RF In loss can be added manually, or automatically by performing an insertion loss measurement. For measurement instructions refer to "Performing (and Calibrating) a Basic One Port Insertion Loss measurement" or "Normalizing and Performing a Basic Two Port Insertion Loss Measurement".
