Spectrum Analyzer
The N9340B spectrum analyzer, also known as the spectrum analyzer, is a relatively expensive test and measurement device. Mainly used for frequency domain analysis of RF and microwave signals, including measuring signal power, frequency, distortion products, etc. More advanced spectrum analyzers can perform demodulation analysis of RF and microwave signals, also known as signal analyzers.
Principle of the N9340B spectrum analyzer
The real-time frequency analyzer has corresponding filters and detectors for different frequency signals, and a synchronized multi-tasking scanner transmits the signals to the CRT screen.
The scan-tuned spectrum analyzer is a local oscillator whose input signal is directly applied to the mixer and then modulated by the attenuator. The scan generator synchronized with the CRT generates an oscillation frequency that changes linearly with time, and is mixed by the mixer and the input signal. wave.
