 Function
2650A, 2652A, 2658A, 2651 common
Marker measurement
NORM：displays frequency (8digits max) and level (4digits max) at marker point.
DELTA：displays frequency difference and level difference between two markers.
Peak search function
Searches for peak level with all of 10 div (NORM mode) or within ZONE specified
(ZONE mode) and displays frequency and level at peak level, and moreover NEXT peak at
NORM mode.
Calculation function
NORM, MAX HOLD, MIN HOLD, AVERAGE, OVER WRITE
Number of sweeps is 2 to 1024 (power of 2 ) and infinite.
Measuring function
Channel power, Adjacent channel power, Occupied bandwidth, Electric field strength
(needs optional dipole antenna), Magnetic field strength (needs optional magnetic field
probe) and Frequency counter
Auto tuning
When pressing AUTO TUNE key, the spectrum of maximum level within full span is
adjusted to center, and reference level, RBW, VBW and sweep time are set to optimum
parameters.
Save/
Load
Save Saves 200 spectrums and 200 setting parameters
Load Loads one spectrum and one setting parameter
