Low-cost but still excellent oscilloscopes for SOHO
After my contribution to the LinkedIn collaborative article https://www.linkedin.com/advice/0/how-do-you-choose-right-oscilloscope, I was asked multiple times for an oscilloscope recommendation.
Believe it or not, I have used a simple 100 MHz 1-Ch Siglent SDS1102CML for about 11+ years. Have I ever needed a better one? Sure, I have but I always find a way how to get my results.
My tips for low-budget scopes:
- 100 MHz 4-Ch 1 GSps https://uk.farnell.com/multicomp-pro/mp720025-eu-uk/dso-4-ch-100mhz-40mpts-1gsps/dp/3107583
- 100 MHz 4-Ch 1.25 GSps https://rigolshop.eu/dho814.html
- 70 MHz 4-Ch 1.25 GSps https://rigolshop.eu/dho804.html
- 250 MHz 4-Ch 1.25 GSps https://rigolshop.eu/dho924.html
