The main points of mathematical function of oscilloscope used for auxiliary circuit analysis
1. Digital oscilloscope mathematical channel can help you analyze hot plug circuit and load switching circuit.
2. The MOSFET MAX5976 hot-swapable device contains a built-in MOSFET switch element, and a current detection and drive circuit, which constitutes a complete power switch circuit.
3. When selecting the oscilloscope probe, make VDS the difference between channel 2 and channel 1, and measure the drain current with the current probe.
4. Resistive loads pull currents that are not stored in capacitors, reducing the accuracy of these capacitance measurements.But for quick measurements, these results are useful.
Most engineering LABS have digital oscilloscopes, but many engineers don't fully use them.The most interesting feature of a digital oscilloscope is its mathematical channel, which helps you analyze hot-swap and load switching circuits.The math function provides detailed information about hot swap circuit parameters, helping you with design and error checking.For example, you can use the mathematical capabilities of an oscilloscope to calculate the load capacitance, which reveals the instantaneous power consumption of a MOSFET when it is powered on or off.
