186 SRM-3006 Narda
Level Recorder mode
Measurement principle Selective level measurement at a fixed frequency
setting.
Detection • Peak
• Root mean square value (RMS), RMS
(integration time = 480 ms, observation time
selectable from 480 ms up to 30 min)
Filter Type Steep cutoff channel filter
Resolution bandwidth RBW
(-6 dB)
40 kHz to 32 MHz (10 steps per decade)
Video bandwidth (VBW) 4 Hz to 32 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
Result Type • Peak ACT: Displays the current (actual) value
• Peak MAX: Max hold function
• RMS ACT: Averaging over a defined time period
(0.48 s to 30 min)
• RMS MAX: Max hold function over the averaged
values, with RMS detector only.
Axis Measurement in the direction of the X, Y, and Z axis
(separate measurement in one direction using an
isotropic / three axis measuring antenna)
Time Averaging Selectable from 0.48 s up to 30 min
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). Only applies to the
numerical result display (Value)
