Harogic SAN-45 is a USB-connected spectrum analyzer for RF development, EMC pre-compliance measurements and signal monitoring. The device covers the frequency range 9 kHz–4.5 GHz and provides a 50 MHz contiguous real-time analysis bandwidth.

The superheterodyne receiver and 14 preselector filters enable a typical DANL of -168 dBm/Hz at 1 GHz. This allows observation of low-level signals even in the presence of strong carriers. RBW range is 0.1 Hz–10 MHz and amplitude accuracy is ±1.0 dB.

The included SAStudio4 software contains nine operating modes, such as phase noise measurement, harmonic analysis and AM/FM demodulation. The API supports multiple programming languages and integration with environments such as Qt and LabVIEW. GNSS and USB-C act as the device interfaces, and the software is compatible with Windows and Linux operating systems.

Optional HOA-90 and HDA-100 antennas can be configured automatically in SAStudio4 with an antenna factor. OCXO reference clock, GNSS, 100 MHz analysis bandwidth and vector modulation and pulse analysis are factory-available options.
