RF Section Description

RF Section Description
This section covers only those optional frequency ranges listed below for the
N9030A Signal Analyzer.
— Option 543, 43 GHz Frequency Range
— Option 544, 44 GHz Frequency Range
— Option 550, 50 GHz Frequency Range
The RF input signal can be routed through four different front end signal paths.
These various paths are switched in and out based on where the signal
analyzer center frequency is tuned.
1. Low band RF path is used when the input frequency is ≤ 3600 MHz
2. High band RF path #1 is used when the input frequency is > 3.6 GHz
3. High band RF path #2 is used when the input frequency is > 17 GHz to
4. High band RF Path #3 is used when the input frequency is > 34.4 GHz to
The RF section is designed to convert RF input signals to an intermediate
frequency that is present at the RF output of the A13 Front End assembly. This
intermediate frequency (IF) depends on installed options and the IF path
selected. This chapter will assume the default operation in Spectrum Analyzer
mode. Therefore the IF frequency will be 322.5 MHz.
