What is meaning of the Measurement range configuration parameter?
The Measurement Range parameter is similar to the reference level of conventional spectrum analyzers. Instead of setting the attenuation (51 settings between 0 and 50 dB), you enter the maximum expected level. This is called the measurement range. The attenuation is set automatically according to the measurement range. Unlike the reference level of conventional spectrum analyzers, the measurement range does not automatically correspond to the Y-axis reference (upper limit of the Y-axis). This parameter can be set independently in the display menu.
