Honghong Passive Intermodulation PIM Troubleshooting Solution
Programmatic background
The PIM problem is a serious threat to the security and normal operation of the communication system, and also restricts the further development of the communication technology. Nowadays, wireless networks have become more complex. When various signals are combined, PIM sources will be generated, which can easily cause interference and distortion to the LTE signals.PIM can reduce the reception sensitivity of the community, and even block the call. Therefore, how to detect and reduce PIM has received more and more attention. But before detecting and reducing, we have to search, so how to find the PIM source?
External PIM Inspection Requirements
- PIM signal strength is low, requiring high receiver sensitivity.
- PIM signals are multi-order intermodulation, requiring broadband scanning capability.
- Need to pinpoint the PIM source location
Solution Benefits
Determine the source of PIM by simply listening to the sound.
Compact, portable and long-lasting Great for field testing
Excellent acceptance sensitivity, even the smallest PIM can be detected
Use a near-field probe to precisely locate the PIM source
Inspection Process
Installation of the complete set of inspection tools
Turning on audio, setting detection frequency and time
Setting the signal threshold, plugging in the headphones
Near-field probe close to the detection device, listen to the sound to identify the PIM
