The sine wave on a scope is pretty pure and the frequency is 1kHz as stated on the package. All components were provided and the documents well laid out. I intend to develop this kit by building it into a box and replacing the waveform selector jumpers and level pot with a multi position switch and remote pot so it can be used as a very basic and handy signal generator in my toolbox with the output taken to a BNC connector. Nice little kit. ### ⭐⭐⭐⭐ Works well. *by I***H on 23 March 2018* Works well and is easy to build. Amplitude can be adjusted but frequency can't. The frequency of all 4 outputs is 1 kHz. My scope shows perfect wave-forms for all the outputs except the triangle which looks more like a distorted sine wave (see attached photo). As with all Velleman kits, the instructions are superb. ### ⭐⭐⭐⭐⭐ Simple to build, a very useful bit of electronic test gear. *by M***R on 7 June 2018* Couldn't find a ready made, basic signal injector anywhere, so thought I'd get this.Very easy to build and when completed, allowed me to fault find an old Pioneer amp and get it up and running again, so I'm well happy with it's abilities and usefulness. ## Frequently Bought Together - Velleman MK105 Signal Generator Kit, 1kHz Fixed Frequency - Velleman MK101-VP Flashing LED Sweetheart Kit, 1.3" x 2.3" x 1.3" Size --- ## 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.co.th/products/48608765-velleman-mk105-signal-generator-240-v-multi-colour](https://www.desertcart.co.th/products/48608765-velleman-mk105-signal-generator-240-v-multi-colour) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-25*
