The Aaronia AG AR 122/051 I/Q High-Precision Power Spectrum Software Block converts I/Q data via double precision real-time FFT to SPECTRA for the RTSA-Suite PRO Spectrum Analysis Software (not included). The left-hand side input is I/Q, while the right-hand side input is SPECTRA. This unit is designed for use with the SPECTRAN V6 Spectrum Analyzers (not included) and requires the AR 122-011 1M FFT Feature (not included) for full usage.

The AR 122/051 converts I/Q data in real-time to SPECTRA using an highly optimized double precision 64-Bit FFT algorithm. Using SPECTRA instead of I/Q highly reduces the CPU load needed to later on display or process the spectrum data.

The FFT Size can be adjusted from 16 to 268 million depending on the easily adjustable DSP Memory Model setting. Pushing the FFT size to the limit will need a lot of processing time, power, and CPU memory. The FFT Overlapping is fully adjustable up to 99.9%.

The available FFT Windowing functions includes Hamming, Hann, Uniform, Blackmann, Blackmann Harris, Blackmann Harris 7, and Flat Top.
