The Wavetek SAMIII is a signal level meter purpose-built for cable television signal analysis and troubleshooting. It measures signal strength and identifies signal impairments across the 4 to 450 MHz band, with amplitude measurement capability from -40 to +60 dBmV. The instrument combines rugged field construction with flexible filtering architecture, making it suitable for technicians and engineers who require direct measurement of signal integrity in CATV systems. A power overload indicator alerts users when input signals exceed 20 volts peak-to-peak, protecting the sensor amplifier from saturation.
