The UniSource SG-1240 is a state-of-the-art high-performance RF signal generator based upon a PLL synthesizer. It features AM, FM and Phase modulation over 10kHz∼1040MHz. The display resolution of the unit is 10Hz for frequencies up to 500MHz, and 20Hz beyond the 500MHz range. Presetting the output parameters are done easily by storing the desired data into the memory of the instrument.

The memory offers a maximum of 100 storage space. Any stored data can be quickly recalled by simply entering the address. If desired, preset data can be protected against accidental erase. Any error made during the data entries is indicated by an error number which is cross referenced in the manual.

Two remote functions are offered for the UniSource SG-1240. The optional GPIB Interface and Remote Controller allow the user to control the function generator either through a computer or the Remote Controller. The remote control functions, and the high quality outputs make SG-1240 an excellent choice either for production test or a laboratory use. The internal output stage of SG-1240 is protected against reverse power flow in case any external RF power source of up to 25W is applied to the output terminals by accident.
