gSE Measurement Options
The gSE Measurement options apply to the Alternating gSE and Continuous gSE
measurement modes. These settings affect the gSE Overall or gSE FFT
measurements.
In this field Values are Comments
Full Scale The maximum signal level expected to be processed by the channel for
gSE measurements. This value is used to determine the programmable
gain settings across each stage of the channel’s analog signal processing
circuit. The default value is 20 gSE.
High Pass Filter Choose the high pass filter to apply to the gSE measurement.
• 200 Hz
• 500 Hz
• 1000 Hz
• 2000 Hz
• 5000 Hz The high pass filter is useful in removing low frequency signal
components that could otherwise dominate the signal. The
high pass filter attenuates frequencies less than the selected
frequency. It allows, or passes, frequencies greater than the
selecteded frequency.
Frequency maximum Enter the maximum frequency for the gSE spectrum, 10 to 5000 Hz. The gSE spectrum always uses asynchronous sampling mode
and the FMAX is always in Hz.
Number of lines Choose the number of lines (bins) in the gSE spectrum measurement:
• 100
• 200
• 400
• 800
• 1600 This determines the frequency resolution of the gSE
spectrum.
