PIM PIM Apparatus and portable apparatus for detecting Passive intermodulation and method thereof

摘要

A passive intermodulation (PIM) detection apparatus according to an embodiment of the present invention includes a tone signal input part for applying a tone signal having a first frequency characteristic to a test device; a sequence signal input part for applying a sequence signal having a second frequency characteristic to the test device; a PIM detection part for receiving a PIM signal from the test device and detecting the delay time and size of the PIM signal based on the sequence signal; and a PIM position determination part for determining a PIM generation position by using the delay time and size of the PIM signal. A position where a PIM signal is generated can be accurately detected.
