iii.3.3 FM Histogram
The FM Histogram shows a graph with the distribution of MPX FM deviation
measurements.
► Screen Description
1 MPX Measurements.
•Level: FM signal level.
•MPX: FM Multiplex level (dBr = dB relative to reference level).
•Dev: Frequency deviation of whole band pass filtered MPX.
•Hold: Period of time taking samples.
2 Measurements:
•Frequency: It is the selected threshold for MPX FM deviation.
•Samples: Percentage of MPX FM deviation samples that are equal to the
selected threshold (yellow graph).
•Accumulated: Percentage of MPX FM deviation samples that are equal o
higher than the selected threshold (green graph).
3 Selected threshold for the MPX FM deviation (tipically 75 kHz). Move right-
left to change threshold.
4 .Green graph: Percentage of accumulated samples values for MPX FM
deviation (measured according to the selected standard).
5 Yellow graph: Percentage of MPX FM deviation values (measured according
to the selected standard).
Cursor Functions:

•Right/left: Move cursor to select threshold for MPX FM deviation.
