3.5.10 Spot Measurement Screen
The Spot measurement screen displays the measured results as numerical values.
The settings for measurements or display are made under the Spot menu screen.

About amplitude display
It is possible to monitor the signal's amplitude from
FRA5022
’ s spot measurement
screen.
The amplitude measurement value is the RMS value of the measured frequency
’ s
fundamental wave (sine wave). In FRA, the noise components that differ from the
measured frequency are not measured. It is not possible to display RMS values
including noise or distortion like with a general voltmeter or peak values observed with
an oscilloscope.
