You can also view them together in alternateor inchopmodes. This way you have wired the function generator and the oscilloscope into the circuit. This is the amount of inductance of the device being tested. If you see a line that is not flat, try disconnecting the probe from the oscilloscope. 6. The full isolation makes it ideal for both laboratory and floating signal measurement because it reduces the risk of accidental short circuits. Touch device users, explore by touch or with swipe gestures. Absolutely. On the other hand, increasing 5. How To Measure Inductance With Oscilloscope And Signal Generator. If your tank circuit is placed in parallel with a low resistance (like 50 ohms from your signal generator, for example), the effective Q of the circuit will be reduced, and it will be more difficult to distinguish the amplitude peak when you sweep the frequency. This period T should roughly match the TIME/DIVISION scale selected. The wave begins at the transmitter (shown by first half step on blue probe) and propagates down the transmission line, seen by the yellow probe. How To Measure The Capacitance And Inductance Of Any Device. the current through the inductor will cause a voltage drop over the 50 ohm resistor causing the amplitude of the signal on the screen of the scope to drop. If nothing is plugged into the oscilloscope you should to see a flat line, this means that the voltage of the input is not changing over time. The angular frequency, ω, has units of radians per second.
