VNA Measurements Application Note

Posted on: August 20th, 2021 by James

August 20, 2021
Basic measurements with a Vector Network Analyser In our wireless world the need of RF component testing is one of a key factors to bring a product to market. Devices are getting smaller and are containing more and more complex components. It is a must to have knowledge of complex impedance (or admittance) and reflection / transmission parame...

Real-Time vs. Swept Spectrum Analysers

Posted on: August 20th, 2021 by James

August 20, 2021
Real-Time Spectrum Analyser vs Spectrum Analyser Today the RF industry has to face more and more the open question, how to transport the data from my test device (DUT) to different receiver spots (like to transmit data into World Wide Web). For IoT applications the most common way is, to use wireless transmission of data via common standards like Bluetooth, Wi-Fi or Zigbee. A mo...

August 20, 2021
Wireless Communication and Function The internet of Things (IoT) is one of the fastest growing areas of technology today. In this increasing competitive field, the greatest challenge facing IoT device manufacturers is determining how to create the smallest devices possible without sacrificing performance in terms of range or power. For IoT de...

FM signal transmission and demodulation demo

Posted on: August 20th, 2021 by James

August 20, 2021
Solution: This application note is designed to show FM data transmission and modulation using some common test instruments. An FM transmission consists of a wave who's frequency is modulated, or changed, with respect to an input signal. If the input signal frequency changes, so does the carrier frequency. The modulating signal affects the FM deviation. The total deviation is a function of th...

EMC Precompliance Testing

Posted on: August 20th, 2021 by James

August 20, 2021
Why is Pre-Compliance Testing done? Almost any electronic design slated for commercial use is subject to EMC (Electromagnetic Compatibility) testing. Any company intending to sell these products into a country must ensure that the product is tested versus specifications set forth by the regulatory body of that country. In the USA, the FCC spec...

EMC Precompliance: Conducted Emission Testing

Posted on: August 20th, 2021 by James

August 20, 2021
EMC Precompliance Testing: Conducted Emissions Electromagnetic Interference (EMI) can cause undesirable effects on electronic products. These effects can range from annoying glitches to rendering a product unusable. In an effort to minimise these issues, countries have established standards and limits to products that are being sold within ...

EMC Precompliance: Near Field Probes

Posted on: August 20th, 2021 by James

August 20, 2021
EMC Pre-Compliance Testing: Near Field Probing Solution: Electronic products can emit unwanted electromagnetic radiation, or electromagnetic interference (EMI). Regulatory agencies, such as the FCC in North America, create standards that define the allowable limits of EMI over specific frequency ranges. Testing designs and products for compli...
