Marker
NORM: displays frequency (7 digits max) and level (4 digits max) at
marker point.
DELTA: displays differential frequency and level between 2 markers.
Peak search
NORM: searches a peak point within 10 div.
Available NEXT peak (10 max).
ZONE: searches a peak point within a zone designated by
center and width. Marker moves to a peak point each sweep.
Calculation

MAX/MIN HOLD: 2 to 1024 times, AVERAGE: 2 to 256
Measuring
Display dot number

(The unit displays data in 251 horizontal
dots, but it internally captures the trace in 1001 dots)
Channel power, Adjacent channel leakage power, Occupied frequency
bandwidth, Electric field strength (needs antenna), Magnetic field strength
(needs optional magnetic field probe) measurement.
Resolution bandwidth
3 dB bandwidth
AUTO tuning
Setting range
3 kHz to 3 MHz(1-3step) and AUTO
When pushing AUTO TUNE key, the maximum level spectrum within
3.3 GHz (2650), 8.5 GHz (2658) bandwidth is adjusted to center,
and reference level, RBW,
VBW and sweep time are adjusted to optimum values.
