| Zusammenfassung: | A device and a circuit for testing the performance of a tube core relate to the technical field of electronics and comprise a to-be-tested tube plugging module, an adjustable capacitor, a capacitor voltage source, a first current detection module and a second current detection module. The to-be-tested tube plugging module is used for plugging a to-be-tested tube; one end of the adjustable capacitor is connected with the capacitor voltage source, the other end of the adjustable capacitor is connected with the first current detection module, and the capacitor voltage source supplies power to the adjustable capacitor; the first current detection module is connected with the first pole of the tube to be tested and is used for testing the current flowing through the first pole when the capacitor voltage source is not switched on; the second current detection module is connected with the second pole of the tube to be tested, and tests the current flowing through the second pole when the capacitor voltage source is |
