Master Thesis: Power-Level Optimization for Energy Saving in Testing Laboratory

Join our Team About this opportunity: Radio Performance Verification (RPV) testing uses radio units, power amplifiers, measurement equipment, computers, cooling systems and other infrastructure—often for long test campaigns. The full laboratory setup can consume significant energy, including during idle periods or when equipment runs at higher power levels than testing requires. In this master’s thesis, you’ll assess where laboratory energy is used and develop a practical power-management strategy to reduce consumption without compromising measurement accuracy, equipment safety, test repeatability or verification requirements. The work will focus on operational energy use in the laboratory and help make energy use more visible, test campaigns more efficient and RPV operations more sustainable. What you will do:

• Measure baseline energy use across representative test campaigns, including setup, active testing, idle, standby and shutdown.
• Map consumption across major contributors such as radio units, power amplifiers, signal generators, analyzers, automation servers, cooling and auxiliary equipment.
• Study how RF output power, equipment operating point and test duration affect total energy use per test.
• Develop and assess practical optimization measures, such as improved test sequencing, automatic standby, controlled power-up and power-down, reduced idle time, equipment sharing and cooling set-point adjustments.
• Compare baseline and optimized test campaigns, checking energy use alongside measurement uncertainty, repeatability, requirement coverage and defect-detection capability.
• Quantify energy use per test and campaign, peak and average power demand, idle-period savings, equipment utilization, and estimated annual energy, cost and carbon-emission reductions.
• Recommend improvements to automation, laboratory procedures and future test setups, while respecting warm-up requirements, thermal limits, calibration conditions, safety rules and RPV specifications.

The skills you bring:

• You are currently pursuing a master’s degree in electrical engineering, energy systems, sustainable energy, mechanical engineering, automation, applied physics or a related field.
• You are interested in energy efficiency, measurement and data analysis, laboratory systems, radio-frequency testing or power management.
• Experience with energy monitoring, electrical power measurements, RF equipment, RPV testing, laboratory automation, scripting or data analysis is a plus.
• Familiarity with cooling systems, equipment operating limits, test repeatability or verification requirements is a plus.
