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 se-lection of sine, square, triangle and ttl of sfg-1000 series adequay 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. |
