Title: UNI-T BW specs

I saw this while randomly browsing the internet, and wonder what is the meaning of the BW spec on the page: 25 to 150Mhz...
Does that mean that you cannont measure anything below 25 Mhz? That looks totally weird and, well, pointless to me...

I already own a cool Siglent SDS1202X-E by the way.

Thanks for any ideas on this strange spec...

EDIT: Actually no, you can see in the model lists that models actually start at 25 MHz total bandwidth. That seems like the most pointless scope ever. I guess it is there to set some base price, so that other prices don't seem like a big deal. A typical marketing trick. Except they want you to get a quote to see the price, which makes even less sense.

They have a configurable bandwidth limiter  (all scopes have). A typical limit is 20 MHz, but 25 MHz works too, I guess.

Of course you can probe any signals you like. Enabling the bandwidth limiter just eliminates high frequency noise when probing slow signals.

Welcome to the forum.

The 25 MHz refers to the UTD2025CL model and 150 MHz the UTD2152CL model.
