Marker Functions
Noise Markers
Noise Markers use an averaging routine applied to multiple data-point groups to calculate the readout, which
is typically comparable to using 1 Hz bandwidth filtering. Because the noise marker routine uses groups of
data points for the calculation, the noise marker should not be placed in close proximity to measurable signals.
You can observe this effect by moving the marker further away from a signal until the marker readout
stabilizes to a more consistent value. Noise markers should be used with an RMS/Avg detector type for proper
measurement. When a noise marker function is selected, the marker amplitude value is displayed in dBm/Hz,
which is the noise level within the resolution bandwidth filter. Delta markers can also be put into a noise
function, but the reference marker must also be a noise marker. If they are different functions, one will be
updated to match the other. Fixed markers are not allowed to be set to a noise function, so if a noise marker is
changed to fixed mode, the function will automatically be set to off.
