[The Signal Path] had two Tektronix AC/DC current probes that didn’t work. Of course, that’s a great excuse to tear them open and try to get at least one working. You can see how it went in the video ...

Tektronix introduced the P6042 current probe in 1969, priced at $625 ($4100 in 2016 dollars). It has a probe you can clamp onto a wire carrying current. The output of the P6042 goes to an oscilloscope ...

The N2780A and N2783A oscilloscope current probes from Agilent Technologies provide a flat bandwidth response, low circuit insertion loss, and can take up to 500 A rms. A family of wide-bandwidth ...

An important design objective for voltage and current probes and current monitors is to determine a signal’s characteristics without significantly affecting the signal itself. In other words, the ...

There’s many different ways of measuring current. If it’s DC, the easiest way is to use a shunt resistor and measure the voltage across it, and for AC you could use a current transformer. But the ...

Thank you to reader Tom Schum for his entertaining, informative guest blog about developing a “simple” DC high-Z probe. [md] They say it's a hobby until you sell a few. I'm keeping this in mind. No ...
