Review: Great pocket device - I had purchased this little signal generator to check out my Ham radio roof antenna. I never thought to use it to replace my big old signal generator in my ham shack. I was taking an advanced electronics course at a local college, and was using my old signal generator for class projects. Then my old signal generator bite the dust! So, I pulled out this pocket signal generator and presto, I was in business again! Great pocket device, my only complaint is that the instructions need to be better. You must push the Run button to generate any signal. For the little money I spent on this generator it was worth every penny. The signals were clear until the very high frequencies. The little thing fits in a large work pocket, and I intend to take it up on my roof to check on my Ham radio antenna. ## Features - 1Hz-500kHz DDS signal generator with Schumann resonator: Combines the functions of a high-frequency signal generator and a 7.83Hz Schumann resonator to provide electronic circuit testing with stress-relieving benefits, setting it apart from standard models. - Versatile waveform generation: Produces sine, square, triangle, and sawtooth waveforms. Includes a switchable filter for precise sine and pulse outputs, perfect for oscilloscope calibration and testing audio amplifiers. - Dual power options: Compact and portable, powered via AC/DC adapter or external battery pack (not built-in), suitable for classrooms, labs, or field testing - Complete package with Schumann resonator: The included Schumann resonator enhances mental relaxation while offering reliable performance for engineers and audiophiles alike. - High accuracy & stability: Built with quality pulse chips, accurate resistors, and correction capacitance for stable frequency generation ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.0 out of 5 stars 114 Reviews | ## Images ![1Hz-500kHz DDS Signal Generator with Schumann Resonator, Portable Multifunction Waveform Generator with AC/DC Power, Ideal for Oscilloscope Calibration, Audio Testing, and Stress Relief - Image 1](https://m.media-amazon.com/images/I/71-kuSvTCXL.jpg) ![1Hz-500kHz DDS Signal Generator with Schumann Resonator, Portable Multifunction Waveform Generator with AC/DC Power, Ideal for Oscilloscope Calibration, Audio Testing, and Stress Relief - Image 2](https://m.media-amazon.com/images/I/814aw9FnlOL.jpg) ![1Hz-500kHz DDS Signal Generator with Schumann Resonator, Portable Multifunction Waveform Generator with AC/DC Power, Ideal for Oscilloscope Calibration, Audio Testing, and Stress Relief - Image 3](https://m.media-amazon.com/images/I/71ew1arlfNL.jpg) ![1Hz-500kHz DDS Signal Generator with Schumann Resonator, Portable Multifunction Waveform Generator with AC/DC Power, Ideal for Oscilloscope Calibration, Audio Testing, and Stress Relief - Image 4](https://m.media-amazon.com/images/I/7114-z3n-iL.jpg) ![1Hz-500kHz DDS Signal Generator with Schumann Resonator, Portable Multifunction Waveform Generator with AC/DC Power, Ideal for Oscilloscope Calibration, Audio Testing, and Stress Relief - Image 5](https://m.media-amazon.com/images/I/71gb94WEFSL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Surprisingly Functional, Small, Inexpensive *by W***N on January 21, 2026* Surprisingly functional for such a small and inexpensive unit. ### ⭐⭐⭐⭐⭐ Great pocket device *by C***E on April 5, 2025* I had purchased this little signal generator to check out my Ham radio roof antenna. I never thought to use it to replace my big old signal generator in my ham shack.

The little thing fits in a large work pocket, and I intend to take it up on my roof to check on my Ham radio antenna. ### ⭐⭐⭐⭐ It's okay for the money... *by J***O on April 28, 2025* Works ok for $36. The sine and triangle waves are the cleanest outputs. The other waveforms have some distortion in their output using my digital 12-bit scope, but it's a $36 non-professional waveform generator... Waveform frequency is very accurate. I am surprised how well it worked for the price paid. For home use, it serves it's purpose. ## Frequently Bought Together - 1Hz-500kHz DDS Signal Generator with Schumann Resonator, Portable Multifunction Waveform Generator with AC/DC Power, Ideal for Oscilloscope Calibration, Audio Testing, and Stress Relief - The Electroherbalism Frequency Lists - The Frequencies of Rifing: From the first frequencies discovered by Royal Rife to today (Electromagnetic devices and frequencies for care and well-being) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/661667533-1hz-500khz-dds-signal-generator-with-schumann-resonator-portable-multifunction](https://www.desertcart.vu/products/661667533-1hz-500khz-dds-signal-generator-with-schumann-resonator-portable-multifunction) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-15*
