30 MHz–6 GHz V/UHF Receiver
The SP-8385 is a VHF/UHF receiver with a tuning range of 20 to 6000 MHz. It provides an automatic gain-controlled (AGC) 21.4 MHz IF output that is 4 MHz wide. It also has switchable AM, FM, and LOG detection modes. An internal fast fourier transform (FFT) processor is included to provide streaming FFT data over the LAN interface. The receiver is based on the SP-8383 tuner with a digital signal processor (DSP) added to perform IF filter, IF frequency conversion to 21.4 MHz, FFT processing, AGC, and AM, FM, and LOG demodulation.
