Product Overview

The SFG-1003 is a 3MHz DDS Function Generator gives a high value solution to the users who need a signal source for accurate but simple measurement applications. The 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 3MHz frequency range and the output waveform selection of sine, square, triangle and TTL available in the SFG-1000 series adequately provide the fundamental functions to ensure high confidence in test results.
  • DDS technique and FPGA chip design
  • Supports 0.1Hz to 3MHz frequency range
  • High frequency accuracy (±20ppm)
  • High frequency stability (±20ppm)
  • 100mHz Maximum frequency resolution
  • Low distortion sine wave (-55dBc, 0.1Hz to 200kHz)
  • Ambient temperature range from 0°C to 40°C
  • Power source AC is 100V/120V/220V/240V±10%, 50/60Hz
  • Dimension is 251mm(W) x 91mm(H) x 291mm(D), approximately 2.1Kg weight
