Introduction GW Instek SFG-1013 Function Generator

The GW Instek SFG-1013 Function Generator delivers accurate, stable signal output for engineers, technicians, and students across Bangladesh. Built on DDS (Direct Digital Synthesis) technology embedded in a large-scale FPGA, this unit generates Sine, Square, Triangle, and TTL waveforms across a 0.1Hz to 3MHz frequency range. As a result, users gain a dependable signal source for filter testing, amplifier verification, and general lab measurements without paying for features they do not need. Consequently, the SFG-1013 remains a popular choice among Bangladesh’s electronics labs, polytechnic institutes, and repair workshops. Astzbd supplies this unit with genuine specifications, a full accessory set, and delivery coverage across Dhaka, Chattogram, and Sylhet.
