SPECTRUM ANALYSIS MODE
Measurement principle
Spectrum analysis
Resolution bandwidths (RBW) (-3 dB)
10 Hz to 20 MHz (in steps of von 1, 2, 3, 5, 10, 20)
List of available RBWs depends on selected sweep SPAN
Video bandwidth (VBW) 0.2 Hz to 2 MHz (depending on the selected RBW)
Measurement range setting (MR)
Set individually from a list or using the “MR Search” function for determining the optimum
measurement range at a given time
Type Gaussian
Filter
Shape factor (-3 dB / 60 dB) <3.8 (for RBW ≤ 100 kHz)
Result Type
ACT: Displays current (actual) spectrum
MAX: Maximum hold function
AVG: Average over a selectable number of spectra (4 to 256)
or a selectable time period (1 to 30 minutes)
Max AVG: Maximum hold function after averaging over a defined number of spectra
Min: Minimum hold function
Min AVG: Minimum hold function after averaging over a defined number of spectra
Standard: Display of the selected safety standard.
Marker functions
Delta marker on one Result Type or for displaying the difference between two Result Types
Highest peak, next peak right, next peak left, next higher peak, next lower peak
Marker field (frequency, level, service name according to the selected service table)
Evaluation functions
Peak table (list of 50 highest peaks)
Integration over a user-specified frequency range
Axis
Isotropic measurement (isotropic result displayed directly)
Measurement of X-, Y- or Z- axis
(separate measurement of a single axis using the isotropic / three-axis antenna)
Display functions
Y-scale range 20, 40, 60, 80, 100 or 120 dB
Y-scale reference MR -100 dB to MR + 20 dB (-130 dB to 40 dBm)
Screen arrangement: Enlarges result display area by hiding other information.
Zoom
Zoom Min: Sets the lower frequency limit of the zoom window
Zoom Max: Sets the upper frequency limit of the zoom window
Zoom Cent: Moves the zoom window along the frequency axis
Zoom Span: Changes the scale of the zoom window
Execute Zoom: Sets the zoom window limits to the selected frequency values
