Spectrum Analysis
(Optional on
8924E)
The LO on the A32 Spectrum Analyzer assembly is swept across the span by the
Controller. The LO starts sweeping when the oscilloscope circuits on the A37
Measurement assembly 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 A37 Measurement assembly and displayed.
Span Width and Bandwidth
Spectrum analyzer resolution bandwidth is determined by switchable bandwidth
IF filters on the A32 Spectrum Analyzer assembly. These filters are set by the
Controller as a function of the span selected from the front panel.
Markers
The Controller keeps track of the marker position set on the front panel and
displays the frequency and level measured for that position. Frequency accuracy
is the same as that of the A27 Reference assembly but it is limited by the
resolution of the display.
Level accuracy can be affected by the logarithmic detector on the A32 Spectrum
Analyzer assembly.
Tracking Generator
When the tracking generator function is selected, the Controller controls the
spectrum analyzer and the RF generator together, causing them to track each
other.
