All these generators were using vacuum tube or Klystron master oscillator, with High Q or cavity tuning circuits, whose fundamental design gave a guarantee of low noise and high spectral purity signal output.Ī real leap forward would need to preserve at least these qualities, and if possible to improve some weakness in the vacuum tube, like for example, the poor stability due to heat dissipation. The 610 and 620 series covered this same requirement for the lower to higher frequencies of the microwave spectra. The 606, 608 and 612 were state of the art signal sources for the measurement of RF, VHF, and UHF receiver performance of the time. First of all, a lot of signal generators, perfectly matching the market needs, were already in the Hewlett Packard catalog by the end of the fiveties. A number of reasons can be listed to explain that. The evolution of the signal generator during the sixties was relatively slow.

If you can’t find yours, chances are it was a printed-only copy and isn’t available for download on our site. While most of our pre-Internet-age models have been discontinued, we do have some manuals, data sheets and software for 1990’s (and older) products on our Tektronix Product Support page. Sweet nostalgia! We’re so glad you still love and use your vintage Tek equipment.
