ABSTRACT:
A high-speed responsive power supply for measuring equipment minimizes the heating value of a load current in the high-speed responsive power supply mounted on a test head. In order to achieve the object, the high-speed responsive power supply for measuring equipment is constructed as follows. The high-speed responsive power supply is incorporated inside the test head which a device under test is detachably mounted on. A remote sensing power supply provided inside a tester body rack disposed a specific distance from the test head feeds a power supply voltage to the high-speed responsive power supply. From the high-speed responsive power supply, an output supply voltage is fed to the device under test. The remote sensing power supply controls the power supply voltage so that a potential difference between the output supply voltage and the power supply voltage will be minimized within a range where the high-speed responsive power supply operates normally. At the same time, a reference voltage power supply inside the tester body rack feeds a reference voltage to the high-speed responsive power supply so that the supply voltage will become a set value.
