Frequently Asked Questions
What is a DDS function generator?
A DDS (Direct Digital Synthesis) function generator uses digital techniques to produce stable, accurate waveforms - sine, square, triangle, ramp, and arbitrary waveforms - across a wide frequency range. DDS generators like the Vartech SGDA series offer much better frequency stability, resolution, and waveform quality compared to older analog VCO-based generators.
Where can I buy a Vartech function generator in India?
CIE Instruments is an authorised Vartech distributor in India. The Vartech SGDA series - SGD-6M (6 MHz), SGDA-15M (15 MHz), SGDA-30M (30 MHz), SGDA-60M (60 MHz with ARB), and SGDA-80M (80 MHz programmable) - are available through CIE with pan-India delivery.

About Function & Signal Generators
CIE Instruments supplies the Vartech SGDA series of DDS function generators - reliable, full-featured signal sources for electronics labs, educational institutions, service workshops, and R&D departments. The SGDA range covers 15 MHz to 80 MHz with sine, square, triangle, and ramp waveforms as standard, with the SGDA-60M and SGDA-80M adding arbitrary waveform generation capability.
The SGDA-15M and SGDA-30M are compact, cost-effective DDS function generators for everyday bench use. The SGDA-60M adds arbitrary waveform generation via PC software, while the SGDA-80M is a fully programmable instrument with USB/RS-232 interface for automated test system integration. All models feature clear digital frequency display and stable output across the full frequency range.
Vartech function generators are available through CIE Instruments as authorised distributors, with delivery to electronics labs, engineering colleges, calibration labs, and manufacturing facilities across India.
