Wavetek SAM1000

The Wavetek SAM1000 is a portable signal analysis meter that functions as an automatic network analyzer for characterizing high-frequency components and circuits. It measures signal levels across RF systems, performs signal quality assessment, and identifies faults in cable television networks. The instrument delivers 80 dB dynamic range with 0.1 dB resolution and ±1.5 dB accuracy, making it suitable for field troubleshooting and laboratory component testing in broadcasting, telecommunications, and CATV environments.
