Talk:NT-7000: Difference between revisions

The NT-7000 was not designed and built by Tektronix Germany.  It was designed and built by a small start up company, Oregon Analog Tools, located in Portland OR.  Tektronix Germany must have signed an OEM agreement with OAS.  The purpose of the NT-7000 was to provide power and signal out from a 7A13.  The target market was SMPS designers, as a differential amplifier with fast over drive recovery is required to make many of the measurements on the switching devices.  When Tek discontinued the 11000 series with the 11A33, no suitable product was needed, although the market still needed a solution.

This unfilled need lead to the creation of another start-up - Preamble Instruments formed by former Tek employees.  The president was an experienced SMPS designer.  I was the engineering manager of Preamble Instruments. The NT-7000 was considered a competitor, but OAS did not have much marketing and few potential customers kenw of it.  Preamble designed the DA-1855, an updated version of the 7A13.  The principle designer was John Addis, a skilled analog design engineer also from Tektronix.  Preamble Instruments was purchased by LeCroy in 1998, and became their active probe and signal conditioner design center.
