Abstract
A test arrangement for testing high frequency electrical devices consisting of two 6-port reflectometers which are both connected to a device under test. In order to calibrate the test arrangement, an arbitrary termination generator is connected to each test port while its test signal represents a reflectivity coefficient of greater than unity, so that it simulates active devices as well as passive ones.
