You can measure current with an oscilloscope using one of the following methods: Measuring the voltage dropped across a shunt resistor.Measuring current with a current probe. Measuring current with a digital multimeter is common. But measuring current that changes over time necessitates the use of an oscilloscope. Most oscilloscopes only detect voltage directly, not … [Read more...] about How to Measure Current With an Oscilloscope

How to Zoom In Oscilloscope
To zoom in or out a signal in an oscilloscope, you need to change the scales of the axes. Use the knob for the horizontal axis and set the µs/div to a lower value. This will allow you to zoom on your signal horizontally. To zoom vertically, set the volts/div of your oscilloscope to a lower value. Zooming in on waveforms allows you to view a detail of the signal … [Read more...] about How to Zoom In Oscilloscope
How to Test an Oscilloscope
For calibrating a 10:1 probe, the majority of scopes provide a test output. Typically, a 1 kHz, 1 V, or 5 V square wave is used. The first stage is to display the square wave with about three periods accurately. Once you have that, you may horizontally zoom in by setting the timebase to smaller values. To view the slope on the screen, you might need to change the … [Read more...] about How to Test an Oscilloscope
Oscilloscope Input Resistance
Oscilloscope input resistance is a part of a complicated impedance, which includes both resistive and capacitive components, can interfere with the performance of circuits being tested and restricts oscilloscopes' high-frequency performance. Oscilloscope Input Resistance When an oscilloscope is connected to a circuit, it becomes a part of the circuit and alters … [Read more...] about Oscilloscope Input Resistance
Oscilloscope DC Offset | Calculation of DC Bias
DC offset is the mean amplitude displacement from zero. It shifts the reference level of your oscilloscope from the original ground or center zero point. The reference level shifts due to the addition of a DC voltage to your output AC signal. This DC voltage is DC offset. DC offset can result in asymmetrical clipping. But it’s deliberately added while measuring small … [Read more...] about Oscilloscope DC Offset | Calculation of DC Bias
