Bias power supply An electronic load is one of the forms of direct current power supply called a shunt regulator, as shown below. Normally, electronic load have the minimum operating voltage predefined. This is because the Vce of a transistor does not work at 0V. Therefore, when you want to perform a “reverse-polarity test of…

Traps for first-time software engineers This story is from early in my career, back when I had little experience with software development. It concerns a blunder I made on a firmware development project. The device I was writing firmware for was designed so that the input and output (I/O) signals could be switched remotely. We…

Four points to try In a situation when you are busy with your work every day, if an error message is issued from a test instrument or equipment you are using or it does not work properly, it is very easy to feel rushed or frustrated. In that situation, how do you solve the problem?In…

Why measurements of the electrical properties of a device connected to a regulated AC power supply differ from those made when the device is connected to mains power It is customary to express the power consumption of industrial devices in Volt-Amps (VA) because they tend to consume a lot of power. Some devices lack a…
