Electrical engineering


This is an apprentice or graduation internship for Bachelor students in Electronics who would like to dive in the problem of how to derive time information from different available (clock) signals at both the master and the slave and how to measure it by means of automation using Python and a very state-of-the-art oscilloscope.

Job Mission

In many industrial applications its required to have very precise time synchronization between different control nodes. The gigabit ethernet interface (GigE) between them allows to implement time-synchronization protocols like IEEE1588 which apply a two way time transfer method. Channel symmetry is key in such method as well as the local timestamp accuracy that determines the time moments used to come to time corrections at the slave.
Demanding applications require high precision synchronization in the order of nanoseconds. For optical implementations this has shown to be feasible. For electrical implementation using copper 1000BASE-T only very limited research is available. A concept has been studied and prototyped using development boards that potentially would allow to achieve very accurate timings over copper interfaces as well.

Job Description

  • Study in more depth a particular Gigabit Ethernet PHY;
  • Create a Python script that allows commanding an existing development kit having a gigE chip;
  • Extend the Python script to allow controlling and reading measurements of a high-end oscilloscope;
  • Create an automated test environment that allows to measure the timing of Master and Slave in subnanosecond resolution;
  • Execute multiple test with different cable length.
  • Document the measurement results and draw conclusions on the achievable precision.


You are a HBO bachelor studying electrical engineering or a related discipline. You are eager to dive in the problem of how to derive time information from different available (clock) signals at both the master and the slave and how to measure it by means of automation using python and a very state-of-the-art oscilloscope.

This is apprentice or graduation internship for a period of about 3 to 5 months.

Please keep in mind that we can only consider students (who are enrolled at a school during the whole internship period) for our internships and graduation assignments.

What ASML offers
Your internship will be in one of the leading Dutch corporations, gaining valuable experience in a highly dynamic environment. You will receive a monthly internship allowance of 500 euro (maximum), plus a possible housing or travel allowance. In addition, you’ll get expert, practical guidance and the chance to work in and experience a dynamic, innovative team environment.

ASML: Be part of progress
We make machines that make chips – the hearts of the devices that keep us informed, entertained and safe; that improve our quality of life and help to tackle the world’s toughest problems.

We build some of the most amazing machines that you will ever see, and the software to run them. Never satisfied, we measure our performance in units that begin with pico or nano.

We believe we can always do better. We believe the winning idea can come from anyone. We love what we do – not because it’s easy, but because it’s hard.

Students: Getting ready for real-world R&D
Pushing technology further is teamwork, and our R&D team is more than 5,500 people strong, with major sites on three continents. Dozens of diverse, interdisciplinary teams work in parallel to meet a challenging development schedule.

In such an environment, your colleagues may be sitting next door, or they could be thousands of kilometers away in a different country, or even working for a different company.

An internship at ASML is your opportunity to get to know this world of industrial-strength R&D and get a feel for that excites you most. Will you design a part of the machine, or make sure it gets built to the tightest possible specifications? Will you write software that drives the system to its best performance, or work side-by-side with the engineers of our customers in a fab, optimizing a system to the requirements of the customer?

How will you be part of progress?
