       SFG-1000 
      Series, an economic function generator with high accuracy and high 
      stability output, is  designed based on the DDS (Direct Digital 
      Synthesized) technology embedded in a large scale FPGA.  The frequency 
      range of 3MHz and the output waveform selection of Sine, Square, Triangle 
      and TTL of  SFG-1000 Series adequately provide the fundamental features 
      to ensure high confidence for the 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 unsophisticated measurement 
      applications.   |
