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 OAT.  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 OAT did not have much marketing and few potential customers kenw of it.  Preamble designed the [[Preamble DA1855|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.
