content: Do any Rigol oscilloscopes auto-sense probes (mainly 1X vs 10X)?My Rigol DS2072A doesn't do that, and I often forget to change the setting manually (and then get confused why the voltages seem 10x higher than I expect).I'd consider upgrading my scope if there were a model that had auto-sensing. Preferably Rigol (since I'm used to their UI and have learned to trust the scope).

content: Which ones? As I said my DS2000 doesn't.MSO5000?Where would this be mentioned on Rigol's website for each product?

content: Not all of them. For example, rigol DS1054z doesn't have additional contacts other than the BNC connector, and can not detect the probe settings or type. More expensive Rigol models can.

content: Do note that even if your scope has the sensing rings, you still need specific probes with the sensing probe and resistor. And switchable 1X/10X probes typically won't have that, with the exception of one Probe Master model. Also, the scope may not sense all probes, my Siglent SDS2354X only correctly senses 1X and 10X, which is annoying when you have 100X probes as well.

content: I'm considering purchasing a DHO924S, which appears to not have the sensing ring. A more expensive alternative might be the SDS1000X HD, which looks like it does have the sensing ring. A look at the SDS 1000X HD data sheet shows that it comes with PP215 probes which seem to be switchable 1X/10X.Can anyone confirm the SDS1000X HD senses a 10X probe? I could use the probes from my old Tek 2465, which I'm used to.My hard requirements for a new scope are 12 bits, logic "analyzer" inputs, 4 channels. I would like about 200 MHz BW and I'm looking to stay below $3000. So, these two models seem the most interesting. The DHO924S is cheaper, but I would have to put up with aliasing in 4 channel mode, and also the 10X sensing. OTOH, the 924 seems much more popular.

content: Quote from: rb720 on January 16, 2025, 08:17:59 pmIf you have a budget up to $3000, you should also consider the SDS2000X HD series, which is a significant jump in power from the lower models. $2400 for the 200MHz model (500MHz hardware).

content: Thank you for pointing out the SDS2000X HD. I see it offers higher sample rates 1 GHz vs 500 Mhz for the SDS 1000X HD. From the boldface in the quote and "100%" from tautech, I'm assuming that 1000X HD has the 10X sensing ring. That would be a nice convenience when switching from probes to a reference signal on co-ax.The 1000X HD and 2000X HD seem very similar except for the sampling rate and memory depth in four channel mode. Anything I'm missing?

content: 200MHz platform vs 500MHz platformexternal vs internal AWGexternal vs internal logic anal.probes that come with the 2000 are 500MHz probes.I dunno what's on the 1000 model, but the handle on the 2000X HD is a really nice, super fantastic, METAL handle. 🤠I have the generic SPL2016 and it works fine for me with my 2000X HD.
