SDS5034X vs SDS2104X Plus

[Sueco]

Interesting fact is that SDS2000X HD has large (much larger that other scopes) offset range. Useful with power electronics work.
500Mhz is more than enough for general purpose scope, especially for power electronics..

That's very good to know, I've found myself struggling with the offset more than one while trying to measure overshoots and such.

As has been indicated, hacking the SDS5034X results in an SDS5104X only on paper; in reality it has a different HW and can never reach 1 GHz. As far as I remember, practical bandwidths were around 850 MHz.

I think that maybe the new hardware revisions all have the same frontend and hardware, but I might very well mistaken. I've been unable to find any definite information regarding that, however some hints point towards that.

The SDS2000X Plus/HD series has a max bandwidth of nominal 500 MHz (with up to two channels), which is actually measured as ~600 MHz. On my specimen of the SDS2504X HD the frequency response is only 1.4 dB down at 500 MHz. So you can use the instrument for 70 cm projects, both in the time (y-t mode) as well as frequency domain (FFT), no worries.

Indeed that's 100% true, with my current scope (100 MHz BW) I've been unable to figure out why some of my flybacks are interfering the commercial aviation emergency communications frequency of 121.5 MHz, with my spectrum analyzer I've been only able to narrow it to the transformer, however I don't know if it comes from some winding resonance or the air gap, although I lean on the latter. That has caused major issues at some major airports and remote receiving stations requiring extensive shielding, which is a problem since all these happened in corrosive atmospheres. I guess with a 500 MHz scope I'd be able to figure out and sort that out. Of course a greater bandwith could be useful in case some issues arise over 500 MHz, however one has to cut at some point and it might always fall short of whatever the future holds to surprise you.
