66 SV 200A User Manual
8.4.1 Configuration views
The Configuration view consists of several tabs that enable configuring measurement parameters
( MEASUREMENT SETUP ), data saving ( STORAGE ), export of measurement data into CSV files
( CSV EXPORT ), audio recording ( AUDIO RECORDING ), events triggering ( EVENT TRIGGERS ),
calibration of the instrument ( CALIBRATION ), auxiliary settings ( AUXILIARY SETTINGS ) and
performing the firmware upgrade ( FIRMWARE UPGRADE ).
To load the new configuration to the station, click the button.
MEASUREMENT SETUP tab
In the MEASUREMENT SETUP tab, you can:
1. Select the Measurement function : Level Meter , Octave 1/1 , Octave 1/3
2. Update the Instrument clock
3. Select the type of RMS/Leq Integration : Linear or Exponential
4. Select Filter ( Z , A , C ) and Detector type ( Impulse , Fast , Slow ) for profiles
5. Select Filter for the spectrum (position appears when the Octave 1/1 or Octave 1/3 function is
selected).
RMS/Leq Integration defines the detector type for the calculations of the Leq , LEPd , Lnn and SEL
measurement functions. Linear integration is required when you wish to obtain the true RMS value of
the measured signal. When this option is selected the values of the Leq , LEPd , Lnn and SEL functions
do not depend on the detector time constant ( Fast , Slow or Impulse ), defined for the profiles.
Exponential integration is required in some standards for Leq measurements. When this option is
selected the values of the Leq , LEPd , Lnn and SEL measurement results depend on the detector time
constant ( Fast , Slow or Impulse ), defined for the profiles.
Such measurement results like Lmax , Lmin , Ltm3 or Ltm5 are always calculated with the Exponential
integration and selected time constants. And vice versa, such results as Lpeak
don’t use integration
at all.
