New Instek SFG-36 3 MHz Function Generator


Instek SFG-36 3 MHz Function Generator

   The New Instek SFG-36 Series, an economic function generator with high accuracy and high stability output, are designed based on the DDS (Direct Digital Synthesized) technology embedded in a large scale FPGA. The 3MHz frequency range and the output waveform selection of Sine, Square, Triangle and TTL available in the SFG-21 Series adequately provide the fundamental functions to ensure high confidence in test results. The DDS technology at an affordable price gives a high value solution to the users who need a signal source for accurate but simple measurement applications.
