Set-up Parameters
Each input can be activated or deactivated using the green dots on the left. When
activated, the set-up controls of a specific input become available. The following table
explains the set-up parameters:
Parameter Description
Range (V) This is the input range. This set-up is not adjustable.
Input Select There are three input types:
Direct DC: This input type can measure the DC signal (no high pass filter).
Direct AC: This input type uses a high pass filter at 0.5 Hz and is suitable for AC signal
measurements.
ICP: This input type includes an integrated circuit preamplifier (ICP) with a high pass
filter at 0.5 Hz. A compatible ICP microphone or accelerometer can be connected
directly to the BNC connector.
Input Description This parameter is a simple text control that allows the user to specify a description of the
input. This information has no impact on the behaviour of the acquisition system.
Unit Name This text control can be used to specify the name of the unit. The unit name is used by
the acquisition system to label of the global level, time and spectrum graphs. For
instance, if a Pa unit is specified by the user for input #1, the Y label of the Spectrum will
be: dB(Parms^2).
Unit dBref The dB reference value is used by the interface for dB computation. For acoustic
measurement with a microphone the standard dB reference value is 2E 5
