WiNRADiO G3XX VHF/UHF Receiver
The Min, Max and Diff buttons enable the display of minimum, maximum and
differential values when continuous sweeping is selected. (A scale for the
differential trace will be displayed on the right-hand side whenever the Diff
button is pressed.)
The differential trace is very useful when investigating activity on a given band.
The receiver can be left unattended in the continuous sweeping mode, and
any activity on the band will be clearly visible on the differential trace.
Note that it is also possible to save a spectrum graph and then load it later to
perform a new sweep to show differences from the old graph, to see what has
changed on the band in the meantime.
The G3XX Spectrum Analyzer also contains special function buttons to locate
peaks in the displayed frequency spectrum:
The Find Maximum Peak button (top left of the four) locates the maximum
peak of the entire spectrum and positions the marker over the peak. The Find
Next Peak (top right) find the next tallest peak. The two buttons below, Find
Peak Left and Find Peak Right, locate the next tallest peaks in the respective
direction.
The Averaging button enables trace averaging. With trace averaging
enabled, the displayed trace is not the actual currently swept trace, but rather
an average of the currently swept trace and the previous trace:
