Just read the above article and learned that my Siglent SDS1104x appears to support a "high resolution" mode.

(Page 44).
If I'm measuring signals below 25mhz, should I be concerned about this? Is it fine to leave the high resolution mode always enabled?

Presumably you mean MHz. No, you wouldn't leave ERES 'on' all the time and you have to keep in mind that there are different levels. Using a larger number of bits worth of ERES may lower your bandwidth well below 25MHz. So for a specific purpose it is a useful feature, but you always have to consider its effects when you use it.

Woops, yeah I did mean MHz.
ERES = high resolution mode?
Alright thanks for the information. I guess I'll need to see where the setting is located and only turn it on during use cases when I don't need additional bits of resolution. Thanks!

Sounds like someone you would use for measuring power supply ripple.
