Spectrum analyzer
The spectrum analyzer (SPEC ANA) mode presents a graphical display of Radio Frequency
against RF level over a selected sweep of the RF spectrum.
Data relating to the setup and to measurements of the signals being analyzed is presented on the
periphery of the display.
As well as the basic spectrum analyzer function, the monitor has a ‘Look and Listen’ function
which allows the operator to listen to the demodulated signal extracted from the RF signal being
examined.
Oscilloscope
The digital oscilloscope function, available from the Tx, Rx and AF test modes, displays signal
waveforms on part of the display screen. The operation of the oscilloscope function is described
in detail later in this chapter under Oscilloscope, starting on page 3-80.
When reference to the oscilloscope facility is necessary when describing other functions, this is
indicated by heading the reference, *
