Kaelus iMT Series Portable Intermodulation Analyzer
Description
The iMT series Passive Intermodulation (PIM) analyzer is an economical, high power PIM test solution. This rugged, simple to operate design enables network operators to improve site performance by finding and eliminating sources of passive intermodulation at the cell site.
It measures IM3 as well as return loss (VSWR) performance of the device under test. Test data can be collected and reported using an external laptop computer.
Features
- Rugged, reliable construction suitable for field use
- Integrated polycarbonate transit case
- Simple LED user interface
- Fixed frequencies, powers and IM product
- Integrated return loss measurement
- PC interface for report generation
