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.

AI Data Center Testing: Power Shelves, Busbars, Burn-In and Optics
AI racks fail on the bench long before they fail in the field. How AI data center infrastructure is actually tested: server power shelves and CRPS supplies, 48V busbars, battery backup units, DC-DC stages, burn-in, thermal validation, high-speed switches, and optical transceivers, mapped to the GW Instek instruments GSAS supplies across India.
Testing High-Power UPS, Solar Inverters and Power Electronics: Inside the GW Instek AEL-5000 AC/DC Electronic Load
India's UPS, solar-inverter and power-electronics makers need load testing that behaves like the real world: non-linear, high-power and scalable. Here is how the GW Instek AEL-5000 AC/DC electronic load covers it, from 1.875 kW on the bench to 540 kW in a three-phase array.
Automated EV Charger Test Bench in India: GW Instek AC Source, DC Load and Battery Emulator
A walkthrough of an automated test bench that validates a CAN-controlled EV scooter charger across the full Indian grid envelope. GW Instek's APS-7200 AC source, PEL-3111AH DC load and GPP-7250 battery emulator combine with a Total Phase Komodo CAN Duo BMS emulator for unattended, repeatable charger validation, designed, integrated and scripted in India by GSAS.
