Narda SRM-3006 185
Safety Evaluation mode
Measurement principle Spectrum analysis, followed by integration over
user-defined frequency bands (services)
Resolution bandwidths RBW
(-3 dB)
• Automatic (Auto), or
• 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 ≈ 1/(RBW)
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)
Display • 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
• 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)
