Embodiment Construction
[0035] Embodiments of the present invention provide a passive intermodulation detection device and method for judging whether a PIM index is up to standard, quickly determining the type of PIM and the location of a PIM source, and providing effective information for users to solve PIM problems.
[0036] see figure 1 , an embodiment of the passive intermodulation detection device 100 in the embodiment of the present invention includes:
[0037] The radio frequency connector 101 is used to obtain the first PIM signal output by the device under test at the radio frequency interface;
[0038] A near-field probe 102, configured to acquire a second PIM signal inside the device under test;
[0039] The processing module 103 is configured to process the first PIM signal obtained by the radio frequency connector and the second PIM signal obtained by the near-field probe;
[0040] The display module 104 is configured to display the first PIM signal processed by the module 103 and the ...
