Wandel and Goltermann - Communication Instruments

Just like Rohde and Schwarz which is a world leader in Communications Test Equipment, There was another from Germany called Wandel and Goltermann which made specialized RF Test Instruments.


A short history is Wandel and Goltermann became Wavetek Wandel Goltermann (WWG) and then Acterna,

See  Willtek Company History. Above are scans of a old catalog of Wandel and Goltermann.

Genrad - General Radio - Instrumentation

History and accomplishments of the General Radio Company, one of America’s first equipment manufacturers for the radio and electronics industry.

General Radio Historical Society

Founded in Cambridge, Massachusetts in 1915, GR provided the tools and instruments that allowed the electronics industry to burgeon into today’s giant that fills our lives with radio, TV, computers, cell phones, DVDs and all the other electronic products in our homes, businesses and automobiles.

Type 608 Oscillator

Type 608 Oscillator - Genrad

The GR 608 was the world’s first R-C oscillator, announced in April of 1939. It was designed by H. H. Scott who worked for GR at that time. It used a separate twin-tee R-C network for each frequency which was selected by a push button.

General Radio Experimenter

This pioneer publication first appeared in June 1926 and became the model for many others to follow (most notably the HP Journal). It began with engineers talking to radio amateur customers and gradually changed to engineers talking to other engineers, who might also be customers.

GenRad 1863 Megohmmeter

GenRad 1863 Megohmmeter

The GenRad 1863 Megohmmeter is the choice for production and inspection tests on devices with resistances up to 20 Tohms. The GenRad 1863 will measure resistance at any of five test voltages of: 50V, 100V, 200V, 250V, and 500 VDC. Compared to the GenRad 1864, which has adjustable test voltages from 10V to 1090V, this unit has fewer controls, and is the more economical of the two models.

General Radio - GR

GR had an interesting philosophy of making instruments that were more modular than HP offerings. On the left is the popular HP 608 signal generator, which covered from 10 to 480 MHz in one unit. It had a zillion tubes, weighed a ton, and cost thousands.

Measurement Basics at National Instruments

For an T&M Learning, Start with these tutors of NI. Like Analog Amplifier Circuits and Analog RC Filters. RF and Microwave Fundamentals if you want to be good at Communication Technologies. Sensor, DAQ and Instrument Fundamentals for Industrial Automation Learning.

Measurement Fundamentals - National Instruments

National Instruments Wi-Fi DAQ devices combine IEEE 802.11 wireless or Ethernet communication, direct sensor connectivity, and the flexibility of NI LabVIEW software for remote monitoring and control of electrical, physical, mechanical, and acoustical signals.

Measurement Basics at National Instruments

NI Wi-Fi DAQ features and to learn how you can simplify wireless remote measurements without compromising on the security or performance of a cabled data acquisition solution.

delabs Notes

You can learn about every niche/domain in Electronic Technologies. You also need to Specialize in a niche which resonates within you. The skill sets need to be broad, in case you find less opportunities in the specialization you have. This keeps changing all the time.

Non-Destructive Testing NDT Resource

Eddy Current Testing (ET) and Infrared/Thermal Testing (IRT) are Interesting Areas where experienced designers can build and manufacture Test Equipment.

Community College Education Resource

These pages have NDT study material for college and Science Educational Pages for High School.

Students can get ideas for original project work on one of these concepts. Choose one area and then research in the web. When i had to build Equipment, it would be difficult to get the catalogs and datasheets of Materials or Methods. Now master the art or searching online, then create your database. Study, Learn and Build !

Direct Read Pocket Dosimeter

Pocket Dosimeter
"Pocket dosimeters are used to provide the wearer with an immediate reading of his or her exposure to x-rays and gamma rays. As the name implies, they are commonly worn in the pocket. The two types commonly used in industrial radiography are the Direct Read Pocket Dosimeter and the Digital Electronic Dosimeter."
