Ramsey COM3010 is a full-featured portable communication tester from the American company Ramsey Electronics. COM3010 is designed for accurate measurement and monitoring of communication devices from 100 kHz to 1GHz. The full-duplex solution allows simultaneous, independent and separate testing of transmitter and receiver circuits. All functions can be easily operated via the instrument’s keyboard and the data is displayed on a high-contrast fluorescent display. The COM3010 is equipped with a Li-Ion battery as standard for field work.
