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. |
