Kaelus (the former Summitek Instruments), has long provided portable measurement solutions for on-site PIM testing, in the form of its iMT series portable IMD analyzers. Several models are available for use at different transmit frequencies, including the 850-MHz band. The testers use two 20-W (+43-dBm) test tones at different frequencies to test for PIM. The analyzers feature exceptional signal sensitivity on the receiver side (about -120 dBm) for simple, reliable on-site PIM measurements of a repeater, cell site, or other communications installation. The firm’s iQA series of testers provides similar portable PIM measurement capabilities, but can also support range-to-fault measurements for isolating PIM problem spots.

The iMT-1000B from Kaelus is a PIM Analyzer with TX Frequeny1 935.3MHz, TX Frequeny2 884.7MHz, RX Frequency 834.1 to 834.1 MHz, Transmitter Freq. Accuracy ± 5ppm (max), aging ± 1ppm (max) after first year, Transmitter Power Accuracy ± 0.5dB (max). Tags: Portable. More details for iMT-1000B can be seen below.
