As EV and HEV platforms scale rapidly, ensuring stable and efficient power delivery in high-voltage converters and charging systems has become mission-critical. Power integrity testing - verifying voltage stability, signal fidelity, and electromagnetic compatibility under dynamic loads - presents unique challenges, including fast-switching transients, wide bandwidth requirements, and the need for precise synchronization across test instruments. Advanced signal generation, waveform creation, and high-resolution measurement tools are essential to simulate real-world conditions and accurately diagnose issues. This is where high-performance signal generators, arbitrary function generators, oscilloscopes, and power meters come together as a complete validation solution. 

Challenges in EV Charging & High-Voltage Power Testing

EV charging systems and onboard converters operate under increasingly demanding conditions: higher voltages, faster switching frequencies (SiC/GaN devices), and tighter

Pressure calibration is one of the most consequential — and most demanding — measurement tasks in oil and gas. From wellhead transmitters and pipeline flow computers to safety relief valves on separators and compressor stations, the accuracy of every pressure device directly affects custody transfer revenue, environmental compliance, and personnel safety.

The operating reality makes this work difficult: assets are remote, environments are hazardous, regulatory windows are tight, and capital budgets swing with the commodity cycle. Asking field engineers and technicians to keep a full inventory of high-accuracy pressure calibrators ready for every application — at every site — isn’t realistic. Renting purpose-built, pre-calibrated equipment when the job demands it is the more practical answer.

The Calibration Challenge in Oil and Gas

A single out-of-tolerance pressure transmitter on a custody transfer skid can quietly cost a producer thousands of dollars per day. A miscalibrated safety

Across industries that operate in harsh or hazardous conditions - from oil and gas fields and mining shafts to defense, aerospace, and remote telecommunications - battery performance isn’t simply a maintenance concern; it is a core operational requirement. Extreme temperatures, corrosive atmospheres, vibration, and unpredictable load conditions can rapidly degrade batteries that power safety systems, sensors, monitoring devices, and critical backup infrastructure. In these demanding environments, engineers rely on battery cyclers, load testers, and precision source measurement instruments to validate performance and detect early signs of failure long before they jeopardize operations.

The Challenge of Battery Performance in Extreme Environments

Maintaining accuracy and reliability in battery performance testing becomes exponentially more difficult in extreme environments. Fluctuating temperatures, contamination, humidity, shock, and long-duration load cycles all contribute to rapid degradation,

Unplanned downtime rarely begins with a dramatic failure. It starts with subtle changes—slightly elevated temperatures, uneven load distribution, early bearing wear, or the faint signature of partial discharge. Thermal and acoustic imaging give maintenance teams the ability to detect these issues long before they escalate, making them essential tools for any predictive maintenance program.

How Thermal Imaging Reveals Problems Early

Electrical and mechanical assets generate heat as part of normal operation. When components begin to degrade, those temperature patterns shift. A thermal camera makes these changes visible in real time, allowing technicians to identify: 

• • Loose or corroded electrical connections
  • Overloaded circuits and unbalanced phases 
  • Failing bearings, misalignment, and lubrication issues 
  • Motor and drive problems under load 
  • Insulation breakdown and hotspots in switchgear 

High‑resolution imagers such as the FLIR T1020 excel in these scenarios. Its advanced optics and
