Reference excerpt

SAF Tehnika (from Latvian: Super Augstas Frekvences, lit. 'Super High Frequencies'; Nasdaq Baltic: SAF1R) is a Latvian designer, manufacturer and distributor of digital microwave data transmission equipment. The group's activities include digital microwave radio equipment for voice and data transmission, microwave spectrum analyzers and signal generators, and wireless sensor network solutions for environmental monitoring. In the year 2004, SAF Tehnika acquired a Swedish company, – SAF Tehnika Sweden, a fully owned subsidiary, based in Gothenburg. In 2008, it was bought out by its management, which rebranded it as "Trebax AB". In May 2004, the company launched an IPO with initial market capitalization of more than €50 million, with substantial subscriptions from institutional investors. The company is listed on the NASDAQ OMX Riga under the symbol SAF1R. During the 2000s, SAF Tehnika expanded globally by establishing a network of authorized partners and sales representatives worldwide.

Worked examples

Example 1 — a first encounter with SAF Tehnika

Start with the simplest possible case. Write down what SAF Tehnika 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 SAF Tehnika 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 SAF Tehnika 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 SAF Tehnika

In research: SAF Tehnika 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 SAF Tehnika 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: SAF Tehnika is common in secondary-school and first-year university syllabi. It links to neighbouring topics Companies listed on Nasdaq Riga, Electronics companies of Latvia, Latvian brands, so understanding it makes those chapters shorter.
In everyday life: Look for SAF Tehnika 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.
