In commission with NTT EAST, we have developed RF Checker 2 to serve all the channels of FLET's/TV lines. The device is designed to measure all the signal strength and quality of NTT EAST's FLET'S/TV channels.
It is a light-weigted, portable device with very competitive price. It can be operated by rechargeable battery (included) or commercially available AC 100V batteries.
The data has been tested at newly installed FLET'S/TV line by NTT EAST.
*It is the only device to measure SkyPerfect TV (*) HD signals as standard. (May 2012)
