Apr 2018 - PCB design - FCC Test of high dynamic range photodiode TIA, SDADC and MCU
Hi Marcus, Just wanted to share with you that we successfully completed a FCC test (part 15) on this device. The operator said "well, there is not much to measure here". Then he wanted to check whether his whole measurement setup actually worked so he put a calibration cone into the measurement chamber, obviously he saw the calibration signal. So he continued saying "oke, this device really does emit nothing". So we were done after only 3 hours! Thanks again for your great work! Eric

Again a splendid experience working with Mr. Hasenstab. Delivered again above expectations and the work is of very high quality. Will definitely hire again.
Feb 2016 - PCB designWas a pleasure to communicate and exchange ideas with Marcus Hasenstab, he challenged our initial design and subsequently delivered a solution beyond expectations. I can highly recommend him.

Resolve PCB Issue
Solid 5 for Marcus. He was a pleasure to work with, english was better than mine, and really knew his stuff. His commitments were all on time, and his work was very thorough. I got a detailed PDF report that had all his analysis, and more importantly he suggested a very simple fix to resolve my issue. I am already planning on rehiring him for my next project. Hire Marcus without any hesitation :)

Marcus is very capable in his field, professional in his demeanor, articulate with a very good command of the English language, and very cooperative. Marcus was instrumental in helping my design team through some technical issues where my staff would have otherwise been stuck. I would highly recommend him for any project.
