S9902 Signal Strength Meter

S9902 Signal Strength Meteris a good kind of CATV Equipment. Key functions: Full digital TV/CATV/FM signal level measurement, Dual channel frequency level measurement, inclination ratio measurement, C/N, V/A measurement, voltage measurement of trunk line alternating current, accompanying sound monitoring and backlight LCD.Features: Features:More convenient and more practical dual-frequency- level measurement. Backlight LCD displays large characters under wide temperature range. Particularity: 0-9 numeric keys enable quickly entering measured channels. Independent function keys enable quickly accessing various measurement states. More than 6 hours of operating time with high performance Ni-MH batteries. Energy saving design, automatically turn off without operations over 5 minutes. User can change the input end by him/herself. More compact, more light. High-intensity and anti-shock materials make it a hard and durable product.
