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).
Joystick Functions:
•Joystick right/left: Move cursor to select threshold for MPX FM deviation.
Function keys:
•F1 Tuning: Tuning options.
•F2 FM: FM demodulation parameters.
•F3 Tools: Tools available for FM.
•F4 Advanced: Advanced Menu.
Advanced Menu
:
•Samples Hold:
-All: It takes samples continuously.
-Time: It takes samples for a period of time.
•Time: Select the period of time to take samples.
•Standard:
-All samples: Histogram calculated according to the ITU-R SM 1268-4
standard. It accumulates all values of frequency deviation into the
histogram.
-Max 50 ms: Histogram calculated according to the ITU-R SM 1268-2
standard. It measures the maxim value of frequency deviation in 50 ms
and then accumulate them into the histogram.
•Reset: It clears and re-starts the histogram.
The Datalogger function stores automatically measurements in a file set by the
user (name, channel plan). User can store for each datalogger measurements
taken at different test points of the selected installation. Measurements are
made for all channels in the active channel plan, both analogue and digital.
Each
installation has its own datalogger files.
Specific measurements for FM (FM Level, Multiplex FM Level and deviation) are
also stored.
