AR's new amplifier, Model 1000A400, provides CW power up to 1000 watts, covering 10 kHz-400 MHz. In conjunction with AR's accessories and antennas, the 1000A400 is optimal for reaching today's higher radiated and conducted susceptibility test levels, such as the increased conducted immunity test levels of composite aircraft in the frequency range of 10 kHz-400 MHz, along with … [Read more...]
The Vital Role of Simulation for Virtual EMI and EMC Test Environments
Before deploying microwave and millimeter-wave devices and systems within 5G, the Internet of Things (IoT), and high-speed wireless communication, it is essential to predict their performance. This need has increased the demand for virtual test platforms through simulation software. High carrier and system bus frequencies are necessary for high-data-rate communication … [Read more...]
Ensuring Performance of Connected Home Electronic Products

The world of consumer electronics needs to evolve and keep pace with the growing desire of their customers and play a part in enabling the dream of a truly connected world. The Internet of Things (IoT) trend has finally reached our homes. … [Read more...]
Würth Elektronik Introduces its WE-CST EE4.4 Current Sense Transformers
Würth Elektronik expands the product family of WE-CST current sense transformers with the new WE-CST EE4.4 series. An innovative manufacturing process not only makes these current sense transformers extremely small (4.7 x 4.65, 3.55 mm), but also provides better insulation. Their insulation voltage of 750 VAC, is 50 percent higher than that of market competitors. The WE-CST … [Read more...]
Circuit Level Design and Test for the MIL-STD-461 200 V/m RS103 and the DO-160 Radiated Susceptibility Test at 200 V/m
Introduction For Army, Navy, and Air Force military equipment and DO-160 commercial aircraft avionics, radiated susceptibility test levels as high as 200 V/m may be specified. As always, it is better to design immunity to the test levels into equipment than to wait until equipment is completed and then perform tests. This article assumes the worst-case qualification test … [Read more...]
MIL-STD-461G Passive Device Calibration Review
The Requirement: When MIL-STD-461 revision “G” was issued, I believed that the answer to many of my measurement equipment calibration issues had been solved. Right there in the “Calibration of measuring equipment” paragraph the requirements clearly stated: After the initial calibration passive devices such as measurement system antennas, current probes, and LISNs, require no … [Read more...]
Test 5G Bands without Massive Cost of New RF Equipment and Time to Train RF Engineers
ThinkRF Corp., the leader in software-defined spectrum analysis, today announced the launch of its new ThinkRF D4000 RF Downconverter/Tuner. The platform is the industry’s first 40 GHz downconverter/tuner that offers a frequency range of 24-40 GHz with up to 500 MHz of real-time bandwidth (RTBW), to capture mmWave 5G signals. Now, engineers can quickly and reliably analyze new … [Read more...]
Review of Induced Signal Susceptibility Testing—DO-160 Section 19
The Issue Induced signal susceptibility has been a factor in electronic equipment performance since the dawning of voltage and current. Often referred to as crosstalk, the undesired coupling of one circuit’s signals to another may result in interference that degrades the integrity of either signal. This article examines the testing process prescribed by RTCA DO-160 Section … [Read more...]
