Rosemary Ainslie COP>17 Heater Circuit - TEST #2

Hi everyone,

Here is the second test of the Rosemary Ainslie COP>17 Heater Circuit replication of the "Quantum" October 2002 article.

It also includes a set of Mosfet Drain 360 Volt spike images and data (spread sheet) .CSV files

All Images and data from the Tektronix TDS 3054C from the Tektronix Corporation
