The value of the maximum values will be deleted on the screen each time that the marker shift
from the current window. Also you can force a deleting of the maximum values on the screen pushing
the “Back” key.
Note: When the mode “Maximums” is selected, the automatic attenuator will be automatically
disabled and it passes from the real time spectrum detection to the Peak mode. In case of variation
of the reference level, use the cursor keys “Up/Down”.
This mode is especially interesting to detect sporadic noise.
10.6 Use of MediaMAX EVO S2 to match the GSM telephony signals
In MediaMAX EVO S2, the satellite band has been extended in its lower part, from 950 MHz up
to 863 MHz, which will make this equipment specially indicated to measure signals coming from
GSM 900 MHz.
It is not needed to carry out any special adjustment to watch these frequencies (between 863
and 950MHz). You can also do it using the numerical keyboard (pressing the key “123/ABC”
and then introducing the frequency with the numeric keys at front panel), or directly turning the
rotary key in frequency mode, like you would do in any other satellite frequency.
With a simple sweep of the Standard spectrum it is very diffi cult to see the GSM signals, due
to they are spread spectrum signals that varies its frequency very fast. With the “Maximums”
mode of detection, capturing these signals is possible.
To measure GSM signals in band 900 MHz, enable the mode “Maximums” like is described in
the previous chapter, and place the spectrum around 900 MHz.
