Equipment and Assets, some of them

Pressebo Electronics has the latest and the greatest technologies and the most sophisticated instruments for to solve some really difficult problems!

Well, there is also a very fast 486 (1997!) with a lot of good programs. A few here below:

For design, simulation, analysis and optimization of RF and µW circuits I use =SuperStar= Pro by Eagleware. http://www.eagleware@eagleware.com/ for a visit to the land of the Eagle!
Dr. Randy Rhea has done a great job in the design of this program cluster.
I have a data acquisition board in the computer as well, allowing for control and measurement of events, sweep frequencies, rotate antennae, vary temperature, run the spectrograph (have two) or whatever the task at hand requires. It greatly facilitates automated measurements, and the presentation of results.

I can do "Voice Prints" for forensic analysis of voices and other sounds, zoological applications or for analysis of noise and vibration in general. (Thanks to Richard S. Horne!) |
Finite element analysis is another capability for analyzing electric, magnetic, thermal fields as well as for mechanical stress, strain and deformation. (Thanks to Yves Borlez!) |
Among lots of other instruments, I may mention a 275 MHz oscilloscope (HP1725A), sampling scope (1 GHz), storage scope, spectrum analyzer (HP8551 with the YIG pre-selector), another spectrum analyzer, 1-18 GHz. HP oscilloscope camera, frequency meters and standards frequency, resistance and capacitance, wave analyzers, vector voltmeter. Grid-Dip meters covering 100 kHz to 900 MHz. Precision DMM's, universal impedance, capacitance and Sheering bridges. Electrostatic voltmeters, stable and swept frequency sources. AM and FM generators, function generators, mixers, attenuators....

My heart always ticks a little faster near good old equipment! Naturally, I have modern stuff too, but these are special! The "Valve Characteristic Meter Mk III" by the English company AVO is just what it says. One can take up all the static parameters of a tube. It is not just a "Tube Tester". An ingenious system with tapped transformers eliminates the need for stabilized power supplies, the subject of a Ph.D. thesis and a few patents quite some years ago. I heard that the Swedish rep for AVO threw a whole truckload of these on the dump. They had not sold any for a long time. I guess nobody knew they had them. It still ought to be the best one ever.
Another great one by AVO is their "Model 8 universal AvoMeter". It is very accurate. 1 to 2 % inaccuracy is promised. I have two of them, and have worked with, and on, many of them. They seem to always be better than 1%. One unusual feature is that one can measure AC voltage and current both, and read it on the same linear scale as the DC measurements. They use a current transformer. The instrument also has a fine mechanical overload cut-out, that can be reset by the push of a button.
The mechanical department is served by a 7" lathe (Myford) with all the gears for metric and English threads, an Italian Rosa bench drill, grinding machines, band saw, hand tools, indicators, calipers and micrometers. And the experience to use them. I may come up with a few pictures of them as well.
For optics, there are two spectrographs (Perkin-Elmer and Fisher) covering 200 nm to 1 µm with recording facilities. Incandescent and Deuterium lamps. PMT, APD and PIN detectors. A 45 mm 40x auto collimator for checking and adjusting optics, telescopes, microscopes (one laboratory with camera adapter and a good set of objectives and two stereo microscopes), cameras, 35 mm with good set of lenses, mostly Canon F-1, a Linhof Technica with a 150 mm f/4.5 Voigtländer Apo-Lanthar apochromatic lens, sheet, roll film and Polaroid back. Film cameras D-8, Rx-8 and Rx-16 mm by Bolex Paillard with Macro-Switar and regular Switar lenses.
A Keuffel & Esser auto collimator with a 10" level on top.
Resolution is diffraction limited, for a 40 mm objective, to 3".
7.25 kg (16 lbm) of Invar and some glass..
