Troubleshooting EMI in Embedded Designs

Today, engineers need reliable data fast, and to ensure compliance with regulations for electromagnetic compatibility in the most economical way, appropriate measures must be taken early in the design phase. This paper provides a brief introduction to embedded EMI troubleshooting challenges and how to use a digital oscilloscope to debug the two key culprits of EMI – switching power supplies and power amplifiers. The Rohde & Schwarz R&S®RTO series oscilloscope provides time correlated multi-domain analysis often required to troubleshoot the complex time and frequency domain embedded design challenges.

IEC 61131-3 Now in Motion

The IEC 61131-3 standard defines 5 programming languages for PLCs and distributed control systems. More recently, dedicated motion companies such as Trio Motion Technology are incorporating the standard into their motion control hardware. By adding specific functions such as camming, electronic gearing, and interpolated motion the controllers have a widely supported usability on the factory floor. Additionally, such controllers can be very compact in size and low cost making them a good choice for a vast array of machines.

HIG™: Combining the Benefits of Inductive and Resistive Heating

Harmonic Inductive Gain (HIG™) is a rapidly growing technology that is changing the game in what has previously been a stagnating technology; inductive heating. HIG utilizes a pulsed output signal rich in high frequency harmonics to deliver an intensely changing magnetic field in place of a sinusoidal signal generated from large currents. This approach allows for efficiency gains that permit air-cooled power supplies and coils to be realized. Modulation of the output pulse allows for precise control over output power with 1W precision regardless of coil configuration, coil type, or load type; affording full flexibility in coil design. The resultant system is incredibly versatile and intelligent offering the same ‘plug and play’ design flexibility as resistive heating while maintaining the highest level of efficiency and reliability available with induction.

3D Printing with FDM: How it Works

A 3D printer is a machine that creates objects from plastic or other materials using an additive manufacturing process. Additive manufacturing produces objects in a succession of layers from the bottom, up. This is the opposite of traditional subtractive manufacturing processes.
