The '''Tektronix 7F10''' is an optical-input vertical plug-in [[introduced in 1987]] for [[7000-series scopes]], at a price of $6,495 (2018 value $14,400).
The '''Tektronix 7F10''' is an optical-input vertical plug-in [[introduced in 1987]] for [[7000-series scopes]], at a price of $6,495 (2018 value $14,400).
The 7F10 has 10 kHz — 750 MHz bandwidth in a [[7104]] mainframe (400 MHz in [[7904|79xx]], 300 MHz in [[7844|78xx]]).

The '''7F10A''' has DC — 1 GHz bandwidth and appeared only in the 1989 catalog, without price indication. Like the [[11F10]], which also was advertised in the 1989 catalog, it was not released to the market (private information from the pricipal developer of the 7F10A / 11F10, Wanda Yantis).

Both 7F10 and 7F10A are specified for the 700 nm to 1550 nm range of optical wavelengths. Both use germanium avalanche photodiodes as the O/E converter. The 7F10A and the 11F10 used Ge-APDs cooled by a Peltier cooler.
