7B10

Manuals – Specifications – Links – Pictures

The Tektronix 7B10 is a 1 GHz time base for 7000-series scopes, in particular, the 1 GHz 7104 (typically used with 7A29 vertical amplifiers and a 7B15 delaying time base).

In effect, the 7B15/7B10 pair are improved-speed versions of the 7B85/7B80.
