Function
Marker measurement NORM displays frequency (8 digits max) and level (4 digits max) at marker point. DELTA displays frequency difference and level difference between two markers.
Peak search NORM: searches peak point within 10div (full freq. range). This mode also supports NEXT peak ( up to 10). ZONE: searches peak point within a zone designated by center and width
Calculations NORM, MAX HOLD, MIN HOLD, AVERAGE, OVER WRITE MAX/MIN HOLD: 2 to 1024 AVERAGE: 2 to 256
Measurements Measure Channel power, Adjacent channel leakage power, Occupied frequency bandwidth, Electric field strength (requires antenna), Magnetic field strength (requires magnetic field probe)
Auto tuning Automatically scans the full bandwidth, sets center frequency to the maximum signal within full span and centers it onscreen. Automatically adjusts reference level, RBW, VBW and sweep time to optimum values
Save/Load
Save Saves 200 reference spectrum measurements and 200 setups
Load Loads one reference spectrum measurement and one setup
