Anritsu entered the PIM testing market last year demonstrating Distance-to-PIM capability and I understand that a Korean manufacturer started showing a "Distance to faulty PIM" product at CommunicAsia mid 2011. Kaelus (formerly Summitek Instruments) is now officially in the game with the introduction of Range To Fault - the combination of Return Loss vs. distance and PIM vs. distance in a single measruement. http://www.kaelus.com/News/Press-Releases/Kaelus-Introduces-Range-To-Fault-(RTF)-Technology/ Regardless of who you purchase from, I believe this technology will greatly speed the time required to perform PIM repairs in the field. It would be great to see testimonials from people using this technology in the field. Please post your experiences!
