Spectrum Analysis (option 102)
The LO on the Spectrum Analyzer, see
swept across the span by the Controller. The LO starts sweeping when
the oscilloscope circuits on the Measurement board trigger the display
sweep to start. As the LO sweeps, the spectrum analyzer filters and
then amplifies the IF signal in a logarithmic detector so the signal
voltage will be proportional to the log of power. The signal voltage is
measured by a sampler on the Measurement board and displayed.
Spectrum analyzer resolution bandwidth is determined by switching
bandwidth IF filters on the Spectrum Analyzer. These filters are set by
the Controller as a function of the span selected from the front panel.
