WHAT IS THE DIFFERENCE BETWEEN AN OSCILLOSCOPE AND A SPECTRUM ANALYZER / SIGNAL ANALYZER? Refer to this Spectrum Analyzer and Signal Analyzer technical overview for more information. Signal analyzers measure both the magnitude and phase of an input signal at a single frequency. Spectrum analyzers measure the magnitude of an input signal versus signal frequency. WHAT IS THE DIFFERENCE BETWEEN A SIGNAL ANALYZER AND A SPECTRUM ANALYZER? A signal analyzer combines the superior dynamic range of a swept tuned spectrum analyzer with vector signal analyzer (VSA) capabilities and enables in-channel measurements like error vector magnitude (EVM) that requires both magnitude and phase information. WHAT DOES A SIGNAL ANALYZER DO?Ī signal analyzer measures both the magnitude and phase of an input signal at a single frequency. For more information, refer to this Spectrum Analysis Basics application note for more information. Spectrum analyzers enable tests like noise figure and signal-to-noise ratio (SNR) to characterize the performance of a device and its contribution to overall system performance. Sub-GHz functionality requires an inserted SD cardFREQUENTLY ASKED QUESTIONS - Signal Analyzers (Spectrum Analyzers) WHAT IS A SPECTRUM ANALYZER USED FOR?Ī spectrum analyzer measures the magnitude of an input signal versus its frequency over the full frequency range of the instrument to determine the power of signals. For more information about the update procedure, see the firmware update page. Sub-GHz functionality requires an inserted SD card įlipper Zero stores databases on a microSD card, so please update your Flipper Zero firmware with a microSD card inserted before using the Sub-GHz feature.
