LEVEL RECORDER MODE
Measurement principle Selective level measurement at a fixed frequency setting.
Peak
Detection 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 seconds 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 0.96 seconds up to 30 minutes
(0.96 s; 1.2 s; 2.4 s; 3.6 s; 6 s;12 s; 18 s; 30 s;
1 min; 2 min; 3 min; 5 min; 6 min; 10 min;15 min; 20 min; 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)
SCOPE MODE (OPTION)
Measurement principle Selective level measurement at a fixed frequency
Filter Type Steep cutoff channel filter
Time Span 500 ns to 24 h
Time Resolution
Selectable from31,25 ns up to 90 min
(0.96 s; 1.2 s; 2.4 s; 3.6 s; 6 s;12 s; 18 s; 30 s;
1 min; 2 min; 3 min; 5 min; 6 min; 10 min;15 min; 20 min; 30 min)
Resolution bandwidth RBW (-6 dB) 40 kHz to 32 MHz (10 steps per decade)
Measurement range setting (MR Range)
Set individually from a list or using the “MR Search” function for determining the optimum
measurement range at a given time
Video bandwidth (VBW) 4 Hz to 32 MHz (depending on the selected RBW)
ACT: Displays the current (actual) value.
Standard: Displays the selected safety standard.
or
Result Type
Depends on detector
MAX: Maximum value within the time resolution interval (corresponds to peak detector).
AVG: Average value within the time resolution interval (corresponds to RMS detector).
MIN: Minimum value within the time resolution interval.
Standard: Displays the selected safety standard.
