content: Hi,I have a DS1054Z that I use only once or twice a year. It's the first time I try to use it with more than 2 channel, and I just now understand that two of the brobe arrived with a broken hook (way to late for warranty). I want to buy replacement probes for cheap (since I don't often use the scope anyway, only for home hobby), but wat wondering if I should spend $10 or $20 and what would the difference be.if I take e.g.https://fr.aliexpress.com/item/32350418957.html?spm=a2g0o.store_pc_groupList.8148356.14.7d652f70b8lZt6&pdp_npi=2%40dis%21EUR%21%E2%82%AC%209%2C36%21%E2%82%AC%207%2C87%21%21%21%21%21%402100bde316695451889566626eda1f%2110000000562296834%21sh, for 12€ there is a pair of probes with these specs :- 100MHz, 3.5ns rise time- 1X (1MR 2%, 70-120pF, 200V) and 10X (10MR 2% 13-17pF, 600V)- 120cmthe original PVP2150 from rigol gives :- 1X: 35 MHz, 10ns, 1 MΩ ± 1%, 50 pF ± 20 pF, 150 V rmcat II- 10X: 150 MHz, 2.3 ns, 10 MΩ ± 1%, 10 pF ± 5 pF, 300 V rmcat IIwhich seems both a bit better and more realistic. From what can be seen in the picture, the building quality seems to be about the same.but the same manufacturer also avec these :https://fr.aliexpress.com/item/32350858868.html?spm=a2g0o.store_pc_groupList.8148356.10.7d652f70b8lZt6&pdp_npi=2%40dis%21EUR%21%E2%82%AC%2013%2C10%21%E2%82%AC%2011%2C13%21%21%21%21%21%402100bde316695451889566626eda1f%2110000001305453197%21sh. The P2100 have the same specs as the first one, cost 13€ a pair instead of 12. From the picture, maybe the plastic is a bit better but I'm not even sure ? Will those make any difference when compared to the original probes ?If I'm looking for "not getting terrible performance for hobby use" and maybe "have somtehing that feel a bit better than the origin probes in hands", do you have any recommandation ?Thanks,John.Side question : can I buy replacement hooks for the original rigol probes ? I did not find any.

content: Quote from: Jaunedeau on November 27, 2022, 11:22:00 amThe current model is PVP3150, of the same spec. There must be a reason for that change. Perhaps Rigol had too many complains so PVP3150 is made of bit better plastics. But the chances are it's even more cheap. Did anyone notice a difference? I'm using PVP3150. It's not a Tek active probe but so far so good.---WBR

content: For the little extra money I'd go with the 200MHz probes. They come with ground springs which are nice to have.Funny, the first ones you linked to are much cheaper to buy if you buy them 1 at a time.

content: Quote from: Fungus on November 27, 2022, 04:59:18 pmReally?For me the P2200 (200MHz) probes are $28.85 CDN for a pair and the P6100 (100MHz) probes are $8.95 CDN for a pair. I wonder why we are seeing such different prices?

content: Quote from: BillyO on November 28, 2022, 01:44:34 amAm I doing it wrong? Oh, yeah... on the "200Mhz" ones I had the wrong option selected.Still, I see €20.53 for the P2200 and €12.52 for the P6100 - nothing like the 3x difference you're seeing.
