If you get the "Sorry, the file cannot be displayed. There seems to be a technical issue ..." error when trying to view an image, a workaround is to click on the cog icon in the upper right side of the media viewer, and then select "Disable Media Viewer". We are aware of the problem and are looking for a solution.
The 7A15 is a single channel, 80 MHz general-purpose vertical amplifier for 7000-series scopes. The AM-6565/U (aka 7A15N11) is the military version of this amplifier. A Department of the Army Technical Bulletin (see links section) suggests that it was used with the 7603 and its military version (the AN/USM 281C).
The 7A15A is a fully discrete design (i.e. no integrated circuits), built mostly from BJTs, with a 151-1032-00 dual JFET as the front-end buffer.
|Bandwidth||0 – 80 MHz (DC), 1 Hz – 80 MHz (AC)|
|Deflection||5 mV/Div to 10 V/Div in 1–2–5 sequence|
|Input impedance||1 MΩ // 20 pF|
