Spect
soft key indicated on the
right hand side of the display and you will be presented with a spectrum display similar to that shown above.
For simplicity the carrier used for identification will be the centre frequency (as indicated by the vertical centre
line on the spectrum display). You can adjust the centre frequency by using the left or right cursor keys and
the frequency information is displayed underneath the spectrum. You can also adjust the amplitude with the
