Hameg

Hameg is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Hameg rather than just read about it. In short: HAMEG Instruments GmbH was a German enterprise specialized in the development and production of laboratory instruments (such as oscilloscopes). The company was located in Mainhausen near Frankfurt, Germany until it was completely integrated in the test & measurement division of Rohde & Schwarz in 2016.

Key takeaways

Hameg belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Hameg to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Hameg from memory before moving on to harder problems.

Reference excerpt

HAMEG Instruments GmbH was a German enterprise specialized in the development and production of laboratory instruments (such as oscilloscopes). The company was located in Mainhausen near Frankfurt, Germany until it was completely integrated in the test & measurement division of Rohde & Schwarz in 2016. As a result, HAMEG as an independent company was closed.

History

The business was established in 1957 by Karl Hartmann in Frankfurt/Main under the name HAMEG KG. The company name is derived from Hartmann-Messgeräte. The first product was a 5 MHz one channel oscilloscope. In 2005, the company founder retired and the business was acquired by the electronics company Rohde & Schwarz with headquarters in Munich. During that time, the name was changed to HAMEG Instruments GmbH. HAMEG maintained subsidiaries in Chemnitz (product development) and Münchenbernsdorf (PCB assembly) as well as a distribution subsidiary in France (HAMEG Instruments France S.a.r.l.). At the end of 2010, HAMEG abandoned the manufacturing locations Mainhausen and Münchenbernsdorf and since then has moved production to the Rohde & Schwarz plant at Vimperk in the Czech Republic. In the wake of this transition, approximately 80 jobs were cut at HAMEG. Other company divisions such as development (Mainhausen and Chemnitz), product management, sales, customer service and quality assurance have remained independent. At the end of 2011, Rohde & Schwarz announced that the company would offer the entire HAMEG product portfolio through its own European distribution network. Only a few months later, in February 2012, HAMEG launched a new product logo. This was the first time that the HAMEG affiliation with Rohde & Schwarz became visible on HAMEG products thanks to the dual name label. As of March 2013, HAMEG products have been made available virtually all over the world through the Rohde & Schwarz distribution network. In June 2014 Rohde & Schwarz announced that in the future all new products from HAMEG will be marketed under the name Rohde & Schwarz.

Products

The range of products offered by HAMEG includes analog oscilloscopes, mixed-signal oscilloscopes (MSO), spectrum analyzers, function generators, RF generators, laboratory power supply units, programmable power supplies and modular laboratory measuring components. The company primarily serves the entry-level segment of the market and is particularly used at electronics laboratories, production supervision as well as at schools and universities. For a very long time, HAMEG was convinced of the benefits of analog technology in the context of the oscilloscope market. In 2004, when HAMEG introduced a new series of so-called CombiScopes (instruments which include both an analog and a digital operating mode), the company stated that "DSOs in principle can not replace analog oscilloscopes". In 2007, HAMEG produced the HM2008 oscilloscope (as shown in the picture) which includes an analog and a digital element as well as mixed-signal functions (4 digital channels). In late 2008, HAMEG introduced the first purely digital oscilloscope with TFT monitor at the electronica electronics trade fair in Munich, Germany. As all subsequently introduced instruments, these oscilloscopes include mixed-signal functions (8 or 16 digital channels) and the option to decode serial buses such as I2C, SPI, CAN and LIN. For instruments with TFT monitors, HAMEG skipped the entire generation of the classical, purely digital storage oscilloscopes (DSO) without MSO functions. By 2012, HAMEG had developed a product range of 11 MSO instruments and one analog oscilloscope. In autumn of 2012, HAMEG announced intentions to soon discontinue production of analog oscilloscopes. Allegedly, this decision was partly due to obstacles in sourcing cathode ray tubes. In February 2013, HAMEG introduced a new series of mixed-signal oscilloscopes with up to 500 MHz bandwidth.

Worked examples

Example 1 — a first encounter with Hameg

Start with the simplest possible case. Write down what Hameg claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hameg before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hameg ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hameg

In research: Hameg appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Hameg in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Hameg is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1957 establishments in West Germany, 2016 mergers and acquisitions, Companies based in Hesse, so understanding it makes those chapters shorter.
In everyday life: Look for Hameg outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Hameg in simple terms?

Why does Hameg matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.
