- no idea about the bandwidth spec. It was probably meant for the slow differential amplifiers and the current probe amplifiers
- I saw two of these, interestingly, both were loaded with two 7A13 differential comparators

- 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 (Switching Mode Power Supply) 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 available, although the market still needed a solution.
- This unfilled need led 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 knew of it. Preamble designed the DA-1855, an updated version of the 7A13. The 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.
