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 79xx, 300 MHz in 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.
The 7F10 uses the main amplifier board of the 7A29 1 GHz vertical amplifier plug-in.
Tektronix provided no schematics for the O/E converter module. A manual (provided by third party) is the "7F10 O/E Module Manual".
