In the mid-1970s, Rockland Instruments was a small company driven by brilliant engineers who thought outside the box to create state of the art instruments. It was no surprise that Wavetek, which had greater resources and name recognition, bought them several years later to get access to their engineering team. | In the mid-1970s, Rockland Instruments was a small company driven by brilliant engineers who thought outside the box to create state of the art instruments.

In 1976 they were among the first, if not the first, to create a spectrum analyzer using an A/D to sample the incoming waveform, convert it into a stream of digital values, perform an FFT (Fast Fourier Transform algorithm) on the data, then use a D/A to convert the results back into the display that appears on the CRT of the 7000 series scope. | In 1976 they were among the first, if not the first, to create a spectrum analyzer using an A/D converter to sample the incoming waveform, convert it into a stream of digital values, perform an FFT (Fast Fourier Transform algorithm) on the data, then use a D/A to convert the results back into the display that appears on the CRT of the 7000 series scope. | ||
HP was not far behind Rockland Instruments. By comparison Tektronix was so deeply committed to swept-IF Spectrum Analyzers that it took over a decade before they realized the advantages of FFT Spectrum Analyzers. | HP was not far behind Rockland Instruments.
