The Viavi TRI-LKG-HL-METER-KIT Seeker HL Leakage Kit for DSP and ONX Series (Software Not Included) includes a hand-held Seeker HL Transmitter that generates two frequencies that can be set at two levels. The receiver is a DSP or ONX meter (sold separately) with an antenna on the input. This means there is no extra high sensitivity meter required to do this test.

The included Seeker HL Source Transmitter monitors 138 MHz and 757.5 MHz simultaneously, supporting testing in both the Aeronautical and LTE frequency bands. The Seeker HL Source Transmitter replaces the cable service with two high-output test carriers which pressurize the subscriber cabling, revealing any damage which may lead to service interruption from ingressing LTE carriers.

The Seeker HL Source Transmitter has two output levels: a +60 dBmV for home certification and a +40 dBmV output level should the subscriber network prove too porous for pinpointing the location of a leak at the higher transmit level.

The displayed leakage levels are normalized by the Seeker HL receiver to reflect the value of the leak at nominal systems levels within the subscriber premise. The normalization of the measured and displayed leakage levels simplifies the evaluation of leakage severity and provides consistency for documentation of leakage levels in accordance with established industry practices.

When utilizing the higher +60 dBmV transmit level the Seeker HL is able to locate signal leakage down to a normalized leakage level of 0.1 uV/m with a single flexible antenna; making it possible to locate and repair signal leakage levels far beyond the measurement range of conventional leakage detectors.
