Tunnel diode outputs, 40 ps rise time with > 200 mV fixed amplitude. Don't overdo this. At the time this test was done (April 2004) it was the fastest realtime scope in the world. We have been using Picoscope 6404D for quite some time, and are amazed by its accuracy and powerful emulations while working with numerous signal evaluations. A high voltage supply trickle charges a small capacitor until the avalanche voltage is reached. The collector is fully saturated with 'holes' (lack of electrons) , and the emitter is fully saturated with electrons. to install this first pre-tine the pad on the PCB. Step recovery diode outputs, < 60 ps rise time the charge held in the capacitor is injected into the 50 ohm resistor creating a very fast transient pulse. A picosecond pulse generator for producing pulses having widths in the or of 10-12 seconds utilizes a Josephson junction that has an external load resistor connected in shunt therewith by a balanced transmission line. Holding the resistor with tweezers, heat the pad with the soldering iron and place the resistor vertically in the molten solder. In order to avoid any inductive effects it is critical that the 50 ohm resistor is a thin-film type surface mount part. The scope has an on board cable compensation mechanism whereby tit uses the internal calibration pulse(15 picosecond rise-time) to compensate away the cable effects. 2.1 Billion points of memory, PER channel. with 2.5 V to 6 V variable amplitude.

Rubbing alcohol can be had at any pharmacy, just make sure you get the 100% and it does not contain other agents such as aloe vera. I had a weird problem - it did not work on one of my PC’s. The emitter wire is bent 90 degrees,trimmed to length,  and inserted in the hollow rear of the SMA connector center pin. The ones further in the tube take a while to roll out. The voltage created is sensed using resistive divider R4 and R5. When the transistor avalanches the electrons close to the transistor are consumed first. The built-up charge in either the waveguide or C2 will reach a point where the transistor will go in controlled breakdown, also called the avalanche effect. This is essentially a chain reaction. The external dual voltage DC power supply is included in the standard At this point the transistor goes into controlled breakdown and dumps the accumulated charge into the output. Tunnel diode outputs, < 40 ps rise time The  original Jim Williams design could accommodate for this if you used a piece of coaxial cable.
