The (Wavetek) '''Rockland 7530A''' is a DC–100 kHz FFT spectrum analyzer plug-in for [[7000-series scopes]]. | |||
Manufacturer was Rockland Scientific Corporation (later acquired by [[Wavetek]]). | |||
The Rockland Instruments 7530A and [[Rockland 7530B|7530B]] plugins for Tek 7000 scopes are outstanding, and unique, Spectrum Analyzers. | |||
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 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.

The only limitation the 7530 has is due to the speed and performance of microprocessor chips available in the mid-1970s. The only solution at the time that would be fast | The only limitation the 7530 has is due to the speed and performance of microprocessor chips available in the mid-1970s. | ||
The only solution at the time that would be fast and precise enough was to create 12- and 24-bit wide CPUs using [[AM25LS381]] bit-slice chips. | |||
The result is a 3-wide 1 Hz to 100 kHz FFT Spectrum Analyzer plugin for the 7000 series scopes that meets or exceeds the specs of the 7L5 in the same frequency range. | The result is a 3-wide, 1 Hz to 100 kHz FFT Spectrum Analyzer plugin for the 7000 series scopes that meets or exceeds the specs of the [[7L5]] in the same frequency range. | ||
