Watchdog system (Tanaka)
Past week report
Examination of experimental preamplifier circuit fabrication. -->
Estimate --> completed. --> Return to the start.
- Because there is a point that the estimate price of the co-op(Univ.Tokyo) is high,and other estimates are taken.
Examination of experimental preamplifier circuit fabrication. -->
- In order to adjust the measurement environment to the site on the report,the result measured using the laptop computer was added.The noise level slightly decreases in the measurement result.As aresult,it was confirmed that there was no problem.
