A second measurement taking the voltage drop over the shunt resistor is necessary. It is not possible to read the voltage drop over the load directly. You also have into account that the channels of most oscilloscopes are single ended, and all measurements therefore must be referred to ground. So, a shunt resistor must be used to obtain the current passing through the circuit, allowing for the computation of the power consumed (Figure 1). Just as a simple example: You want to quantify the power of a certain block in your circuitry, and you are also interested in the waveform originating from these calculations, not only in the absolute values.īut most oscilloscopes only measure voltages, the current, and therefore the power cannot be measured directly. But occasionally, it is necessary to document the obtained data or to process the signals further. If the instrument can also work as a waveform generator and can do some mathematical calculations on the signals acquired, or allows automated tests, even better.įor many measurement tasks that designers face in their daily work, oscilloscopes are an excellent choice as they offer many ways to achieve good results. Oscilloscopes are the tool of choice for every engineer when it comes to measurements.
