An SNA is functionally identical to a spectrum analyzer in combination with a tracking generator . The analyser input is fed to pins 3 and 4 because they are DC-coupled to the diode ring. All contribution to this page are most welcome Purpose Spectrum Analyzer is intended for visual inspection of the spectrum of an investigated signal on the oscilloscope screen. The signal can be continuous or pulsed. Like most of the other plugins for Both were taken with identical spectrum-analyzer settings, displaying the RF spectrum from DC to 1800 MHz at 2 dB per vertical division. RF output on 145 MHz is +6 dBm. Spectrum analyzer set center frequency set on 145 MHz. Hence, this simple homebrew probes had satisfied my requirement.
