Added Pulse Generator Pages

I tried to create some fast and/or high voltage pulse generators using either avalanche pulse generation, tunnel diodes, snap diodes or transistor circuits.

Added a Noise Figure Measurement Solution for the Poor (using a DSA815)

A lot of my ham colleagues have a budget spectrum analyzer like the DSA815, but no possibility to make noise measurements due the high noise floor of this entry level instrument. Using some additional, not too complicated hardware it is possible to do accurate noise measurements with it, nevertheless.

It works by using a noise source, an LNA and two transfer switches.

High Voltage Power Supply Pages Added

Today I added some pages about the high voltage power supplies I have made.
