Moku:Pro’s Spectrum Analyzer

Compare all spectrum analyzers


Moku:Pro’s Spectrum Analyzer allows you to observe input signals in the frequency domain between DC and 300 MHz with an ultra-low noise floor. View four channels simultaneously with a resolution bandwidth as low as 2.2 Hz and a minimum span of 100 Hz. The Spectrum Analyzer also features four 500 MHz sinewave generators.
