SGM131 Signal Generator Module

SGM131 series signal generator module can generate signals with frequency up to 3GHz. It has excellent performance and compact size, and has various working modes such as CW signal, analog modulation, pulse modulation, digital modulation, amplitude /frequency sweep, linear frequency modulation and up-conversion. SGM131 series is suitable for education and research, product development and system integration.

The A-type module focuses on analog signal modulation, and its maximum analog modulation rate is up to 1MHz. The B-type module focuses on digital modulation and has a built-in IQ modulator, which can flexibly support input I/Q modulation of baseband data such as various communication data links, standard public network communication standards, and cable digital TV broadcasting. The maximum baseband modulation bandwidth is up to 20MHz, which is convenient for The user builds the experimental platform. Complete standard SCPI command set and general USB and LAN interfaces bring great convenience to your remote control and secondary development.
