SAFETY EVALUATION MODE
Measurement principle
Spectrum analysis, followed by integration over user-defined frequency bands (“services”)
Resolution bandwidths RBW (-3 dB)
Automatic (Auto), depending on the narrowest user-defined service bandwidth, or user-
defined (Manual) for all services, or separately defined for each individual service (Individual)
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
Detection Root mean square value (RMS), RMS (integration time =
RBW
1
≈ )
Filter See Spectrum Analysis mode
Result Type See Spectrum Analysis mode
Marker functions
for bar graph view
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 Function Distribution
Axis
Isotropic measurement (for direct display of the isotropic result)
Measurement in the direction of the X, Y, and Z axis
(separate measurement in one direction using an isotropic / three-axis measuring antenna)
Table view showing service names, field strengths, RBW and the corresponding frequency
band (up to three columns)
Individual screen arrangement
Sort function according to various criteria
Display
Bar graph of services showing contribution of different Result Types
Noise suppression
Identifies whether measured values are above the device noise floor by setting a threshold
(selectable at 0, 3, 6, 10, 15, or 20 dB relative to device noise floor).
Measurement values below the threshold are shown as the absolute threshold value marked
with “<” (less than threshold)
Others On / Off
Measurement of services and gaps in the Service Table (Others On) or
Measurement of services in the Service Table excluding gaps (Others Off)
