Noise Cancellation
The R&S FSV/A can correct the results by removing the inherent noise of the analyzer,
which increases the dynamic range.
In this case, a reference measurement of the inherent noise of the analyzer is carried
out. The measured noise power is then subtracted from the power in the channel that
is being analyzed (first active trace only).
The inherent noise of the instrument depends on the selected center frequency, resolu-
tion bandwidth and level setting. Therefore, the correction function is disabled when-
ever one of these parameters is changed. A disable message is displayed on the
screen. To enable the correction function after changing one of these settings, activate
it again. A new reference measurement is carried out.
Noise cancellation is also available in zero span.

8.4.3 Scaling the Y-Axis
The individual scaling settings that affect the vertical axis are described here.
Access: "Overview" > "Amplitude" > "Scale" tab
Or: [AMPT] > "Scale Config"
The remote commands required to define these settings are described in Chap-
ter 14.7.3, "Configuring the Vertical Axis (Amplitude, Scaling)", on page 898.
