Because this circuit can generate a very loud tone, a 5K potentiometer can be used to turn down the volume. Press the (normally open) test button to validate that the tone circuit works properly ...

Why DC testing is important, what tests are most common, and how preventive maintenance can make all the difference in preventing circuit breaker failure ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop?

Link to Vojtě ch Janásek's article, “Low-distortion oscillator tests measurement circuits.” Today’s 20-bit to 24-bit ADCs need low-distortion signals for testing how well the ADCs digitize analog ...

In circuit testing (ICT) can be an effective tool for OEMs and contract manufacturers to consistently meet defined parameters during production runs. Our mission is to provide the most appropriate ...

Manufacturers have a great deal of flexibility when deciding where and how to program their devices. Components can be programmed at many stages during the procurement and manufacturing process. This ...

This Idea For Design shows how a gyrator circuit can be used to perform certain ac tests on units under test that require a dc-current feed.

I perform occasional turn ups of larger circuits for clients, in the range of 300mbit to 1gig. The ISP (often CenturyLink in Denver) provides the equipment, handing off to ethernet. Nothing ...

The holidays are just around the corner, which means it”s time to find out how many light strings survived 11 months in the attic. When we find a clunker, the quest for the bad bulbs usually leads to ...

Construction for the three Covid-19 testing facilities began during the circuit breaker period last April when Singapore had a partial lockdown and was completed two months later in June.
