The Elikliv Mini Vector analyzer is capable of supporting frequencies up to 900MHz, as it uses the SI5351 odd harmonic extension. An ideal oscillator would generate a pure sine wave; all the power of the signal is at a single frequency. Product Overview. The MXG brings unmatched phase noise and spurious characteristics. Or . Many analyzers have an RBW filter that has a Gaussian shape and a shape factor determined at the 3 dB point. The spectrum analyzer makes power-versus-frequency measurements by downconverting the signal of interest and sweeping it through the passband of an RBW (resolution bandwidth) filter. In conjunction with being able to see the spectrum of these fast events, the value of VSA software on a scope comes into play when you can set frequency, span, and RBW just like a spectrum analyzer. Spectrum analyzers measure the magnitude of an input versus signal frequency. This cookie is set by GDPR Cookie Consent plugin. Return this item for free.
