Make sure that you're wearing a seat belt when you check the prices. On the other hand, you can do fairly well with any decent counter with a good internal timebase. -- Service to my country?

You'll need say an order of magnitude better spec on your frequency counter reference clock than the one you want to measure. Dave :) | ||||||||||||||||||||||
