摘要

Error factor measuring apparatus (40), which in a signalling system, comprising [1] a first signal generation unit (1), which has a first signal source (10), which generates a first signal, and a first output port (19), said first signal, [2] a second signal generation unit (2), which comprises a second signal source, which a second signal is generated, and a second output port (29), the second signal, and [3] a connecting tool (30), comprising the first output port (19) and the second output port (29) connects to one another, an error factor in the second signal generation unit (2) measures based on a result of the first signal and a result of the second signal, comprising:a measuring unit (42) for the characteristic of a combination tool (30), which is a characteristic of the combination tool (30) measures based on the measurement result of the first signal and the measuring result of the second signal;a measuring unit (44) for the ratio of reflection to output, which a ratio, which relates to a measuring result, after the first..
