Ceyear 1441A/B Signal Generator
With frequency range low to 9 kHz, 1441 Series Signal Generator are economical signal generators designed with portable case structure and featured by small size and convenient operation. 1441 series have power output in wide dynamic range, and standard internal modulation signal generator, are capable of amplitude modulation (AM), frequency modulation (FM) and pulse modulation (Pulse). List sweep and Step sweep make test application more flexible. They deploy Chinese and English operation interface, and large LED TFT LCD.
1441 series can be used for performance test and failure point location of the receiver in the radar, electronic warfare and communication equipment for convenient test, as well as used as a local oscillator to substitute those in the equipment under test, such as transmitter and receiver, etc.. In the civilian market, the series can be applied to the R&D and manufacture of consumer electronic products. The economical RF signal generators are very suitable for teaching and experiment in universities. Portable design of the case makes it very suitable for outdoor operations.
