A modern concept of spectral analysis
Abstract
The 8568A HP spectral analyzer using three built-in microprocessors for machine control, display control and data separation is examined. The analyzer is capable of functioning in the frequency range of 100 Hz to 1500 MHz, and has a bandwidth of 10Hz over the entire frequency range, 90 dB dynamic range on-screen, spectral clarity, and digital storage with full annotation of the screen. The main characteristics are (1) it improves frequency exactness for the oscillators at + or - 100 Hz, (2) it is able to clearly distinguish differing signals similar in amplitude through a new phase-locking system, thus enabling the phase noise level of the oscillators to be improved by 20 dB, and (3) it is easier to use due to digital memories and a keyboard. Attention is given to the frequency and video signal separation, the input frequency and to the analysis of its error detection capacities
