It's been a long time coming, but now I could do with a oscilloscope for testing output noise and ripple of power supplys under load. Also buck and boost converters, I've seen this handy looking scope and wandered if it would be acceptable for the above uses. My budget is limited, I didn't want to go second hand as there's no guarantee it won't have a host of problems. Anyway, if someone could advise on this scope, I would appreciate that. Thanks for reading. Ps. Nearly forgot, it's the Velleman Handheld 40MHz Scope with USB Should have mentioned, it's primarily for testing output power supply ripple. And not so much for repair use. If that scope above isn't suitable, any suggestions on a scope for the same use with in a £250 To £350 budget. Thanks again. |

https://www.amazon.co.uk/Rigol-DS1054Z-RIGOL-DIGITAL-OSZILLOSKOP/dp/B01LNY8CL0 There are few decent scopes in your price range. The DS1054Z is quite popular and the Siglent SDS 1x04 entries are coming along but they cost more when compared 4 channels versus 4 channels. If I were looking for another scope, I might buy the SDS 1104 and unlock it to 200 MHz. The DS1054 can be unlocked to 100 MHz, details elsewhere. We have this discussion every week, you might try the Search feature or look over in the Test Equipment forum. |

I agree with rstofer; if your budget covers the scopes he mentioned, they are much better choices. At what price was the HPS50 offered to you? If it is anywhere near to the budget range you indicated, run away screaming and avoid that seller in the future. The HPS50 is very limited in comparison with the scopes rstofer mentioned -- bandwidth, sampling rate, and sensitivity are much worse, making it almost a toy by today's standards. An it is a discontinued model. Still available new for 170 Euro (150 GBP). |

Thanks for the replys. I will certainly look at the scopes you've mentioned, the HPS50 I can get for about £200 or just over that. I figured it was limited in its function to some extent, so will certainly look up your recommendations. I didn't want second hand as if it has issues, i doubt i have the ability to repair one. But it is really for testing outputs from power supply, or DC to DC converters. |

The DS1054Z should be within your budget. E.g. 380 EUR (325 GBP) here, with free shipping in the EU: https://www.batronix.com/shop/oscilloscopes/Rigol-DS1054Z.html The Siglents might be pushing your limit, unless you forego the 4 channels. Batronix has them as well. (As do other vendors, of course.) |
