The Tektronix 7000 Oscilloscope series

The Tektronix 7000 series is a wonderful addition to any test bench. They are solidly made and often have interesting circuitry. The wide range of plug-ins provide a study upgrade path. If there is one complaint, it is the use of Tek custom ICs. However, given the choice of some piece of unknown 'scope and a Tek 7000, isn't the choice perfectly clear? I'll never understand how someone can buy a random brand when they could have bought a used Tek. Tektronix also has a FAQ for their 7000 series. It tells you about the year of introduction of each mainframe and plugin and not much more.

I have some preliminary notes on interfacing to the 7000 series .

The creation of ebay's test equipment category has resulted in a lot of 7000 equipment on the market.

Here's my mapping from mainframe numbers to specification. A mainframe has 4 digits: 7BTS, where B is the bandwidth, T is the type and S is the number of slots.
