Harogic PXN-45 spectrum analyser
Details
The Harogic PXN-45 is a real-time handheld spectrum analyser covering 9kHz to 4.5GHz. 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.
Another option can be factory-installed: 0 Hz starting frequency (PXN-45 only). Please get in touch if you are interested.
