Harogic PXN-90 spectrum analyser
Details
The Harogic PXN-90 is a real-time handheld spectrum analyser covering 9kHz to 9GHz. It uses a superheterodyne receiver with a full-band preamplifier and up to 14 preselector filters, delivering 50MHz (or optionally 100 MHz) of real-time analysis bandwidth, a sweep speed up to 1THz/s, a -110dBc/Hz phase noise at 10kHz offset and a -168dBm/Hz DANL.
The PXN series stands out for its open platform. It runs Raspberry Pi OS on a Raspberry Pi CM5, so alongside the bundled SAStudio4 software it is possible to install or develop applications using the well-documented SDK and API. SCPI remote control is supported for automated test setups.
Where most brands sell the measurement suite as a set of paid options, the PXN series includes it as standard. SAStudio4 covers swept and gapless real-time spectrum analysis, IQ streaming with DDC, power detection to 16ns resolution, phase noise measurement from 1Hz to 10MHz offset and harmonic analysis to the tenth harmonic.
