Ever wondered how engineers inspect capacitors, resistors, and inductors? The solution is frequently in a device known as an LCR meter. The tool is quite valuable since it measures three significant ...

A multimeter and its test leads allow electrical workers to reach into an energized panel, touch live circuit components with the end of the test leads, and capture electrical readings like voltage, ...

How do you test the oscillator circuit you just made that runs between 200MHz and 380MHz if all you have is a 100MHz oscilloscope, a few multimeters and a DC power supply? One answer is to put away ...

This frequency meter project squeezes a lot of performance out of the ATtiny2313 microcontroller. That chip does all of the work, measuring the frequency on the input pin as well as multiplexing the ...

There is a basic method for measuring high-frequency power using a power meter and power sensor (Fig. 1). The power sensor converts high-frequency power to a dc or low-frequency signal that the power ...

An Atmel AT90S2313 microcontroller is used to build this RS232 frequency meter which can communicate at 9600 baud through an RS232 terminal program which eliminates the use of any front panel controls ...
