Overview
About SFG-1003/1013 DDS Function Generator
The SFG-1003 and SFG-1013 are DDS (Direct Digital Synthesis) function generators designed for education, basic industrial, and entry-level R&D applications. FPGA-based DDS technology delivers high frequency accuracy (±20 ppm) and stability (±20 ppm) at a budget-friendly price point.
Output frequency spans 0.1 Hz to 3 MHz with 100 mHz resolution, sufficient for audio, baseband, and low-frequency analog circuit testing. Low distortion sine wave output (-55 dBc) supports filter characterization and amplifier linearity measurements without requiring an external low-pass filter.
The SFG-1013 adds a voltage display feature for direct output level monitoring. Both models feature PC USB interface for remote control and waveform editing via external PC software, supporting automated test sequences in educational lab environments.

Emulating Processor Power for Thermal Testing: Why Constant Power
A heat sink or a cold plate is qualified against a watt figure, not a volt figure. This application note explains why a thermal load is driven in constant-power mode, how the bench is built for air and for liquid cooling, and what to confirm before you buy.
CRPS and Rack Power Supply Testing: The Six Tests That Matter
A CRPS module has to hold up under an unbalanced grid, a 0 to 100 percent load step, a surge on the line and a redundancy handover. This application note sets out the six tests, and the one source capability that makes a long feeder reproducible on the bench.
GPU Power Board Testing: DC Input Verification Before Integration
A GPU power delivery board is cheap to reject on a bench and expensive to find in an assembled server. This application note covers the programmable DC input test that screens the board, and the same test applied to incoming server systems.
