Rohde & Schwarz has recently rolled out their EFL110 and EFL210 portable TV test receivers. The company's latest offering aims to aid operators in locating loose connections or damage shielding which can generate unwanted electromagnetic emissions in the UHF range and cause interference in cellular LTE networks.

The EFL110 and EFL210 CATV analyser and leakage detectors use FFT analysis to monitor the spectrum and detect even weak, sporadic interferences. For evaluating faults in the US cable TV network, the EFL210 comes with an additional test receiver that supports J.83/B and NTSC cable TV standards. Each instrument is equipped with a lithium-ion battery that supplies power for more than four hours of operation in the field.

Both instruments have a frequency range of 5MHz to 2500MHz; sensitivity of 8 dBµV/m in E-UTRA bands 12, 13, 14, and 17; and sensitivity of 17 dBµV/m in the aeronautical radio band from 108MHz to 139MHz. EFL-Suite software, which is supplied with each unit, transmits the measurement results to a PC.

Datasheet for the EFL110/EFL210 can be found here.
