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.
Table 12 - gSE Measurement Parameters
In this field Values are Comments
Full Scale The maximum signal level that is 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
selected frequency.
Frequency maximum Enter the maximum frequency for the gSE spectrum, 10…5,000 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 number determines the frequency resolution of the gSE
spectrum.
