Abstract
A measuring bridge (1) provides a first matching pad (2), a second matching pad (3) and a third matching pad (4), wherein all matching pads (2, 3, 4) comprise at least three resistors (21, 22, 23, 31, 32, 33, 41, 42, 43) which are arranged in a T-structure. A second resistor (32) of the second matching pad (3) is connected to a second resistor (22) of the first matching pad (2), and a third resistor (43) of the third matching pad (4) is connected to a third resistor (23) of the first matching pad (2). A second resistor (42) of the third matching pad (4) can be connected to a device under test (7). A third resistor (33) of the second matching pad (3) can be connected to a calibration standard (5), and a first resistor (31, 41) of the second and the third matching pad (3, 4) are connected in each case to a signal input of an element (11) which suppresses a common-mode component on its two signal inputs.
