12. Second Converter

This adjustment applies to:
8590L spectrum analyzers
8591E spectrum analyzers
8591C cable TV analyzers
The RF output of the tripler is adjusted by observing an analyzer
connected to the 321.4 MHz second converter output, and adjusting the
slug-tuned cavity for maximum signal.
The second IF bandpass filter is adjusted for a 2.1214 GHz bandpass
using the Dishal method. The second mixer match is adjusted for
maximum output.
The LO is swept through the range of the 2.1214 GHz bandpass while
the output is observed with an analyzer and the characteristics are
evaluated.
