Additional Features: Frequency Range: 0. 1 Hz ~ 3 MHz DDS Technology and FPGA Design High Frequency Accuracy: ±20ppm High Frequency Stability: ±20ppm Max. Frequency Resolution: 100 mHz Low Distrortion Sine Wave: -55dBc, 0. 1 Hz~200 kHz Voltage Display Accessories: User Manual, Power Cord, GTL-101 The Instek SFG-1013 is an economic function generator with high accuracy and high stability output and is designed based on the DDS (Direct Digital Synthesized) technology embedded in a large scale FPGA. The frequency range of 3 MHz and the output waveform selection of Sine, Square, Triangle and TTL of SFG-1013 adequately provides 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.
