Oscilloscope Choice: Yokogawa DL1740EL or Iwatsu DS-5624A or Tektronics TBS2204B
<< < (12/13) > >>
nctnico:
Then again, brand specific active probes are always locked to a manufacturer and may not even work on all models from that manufacturer. So if you buy an oscilloscope from a different brand you'll need different active probes.

There are lots of generic active and passive probes for HF and current on the market which will work with any oscilloscope. These are a better long term investment. Only downside is that you'll need to set the probe scaling factor manually.
KungFuJosh:
Exactly why I mentioned "direct active probe support." He could always get Lasmux's probe when ready.

There is an adapter that should eventually work with different probes on the SDS3000X HD. Not great yet though, but I suspect better support (more probe compatibility) will come in future firmware updates.

You can get active probes that use a regular BNC input. No need to have a scope with that interface support, it's just a more convenient from a powering point of view and auto scale factor set.

Ah nice! if I can get third party ones then the deal for the 200 MHz scope seems like a good option.

Coming back to OP's question ...

... and a bit later ...

I’ll talk to the shop owner and see if he can run the self test before buy.

So it seems to me that spending $1000+ and up to $2500 is perfectly feasible and fine for OP. Hence, while I do understand that a hint at e.g. a modern Siglent scope may be useful, I think basic respect as well as the assumption that OP isn't an idiot and *has done* some thinking about what he is/should be aiming for should be expected.

Wrt his 3 candidates my opinion is that the Iwatsu probably is the best choice. Iwatsu is a very reputable company and the only major drawbacks seem to be that it's somewhat slow and that it's not a MSO (which for me personally is important but maybe not for OP).

IMO the Yokogawa isn't a worthy candidate because of its low sampling rate, and the Tektronix isn't because of its price.

If OP would be willing to consider modern scopes too I'd suggest to look at (only) Siglent scopes, preferably at not too new models i.e. models with mature firmware like the SDS2000X. Why Siglent? Because they are the only chinese manufacturer whom I consider a near-A brand.

Have a nice weekend everyone
