Thanks guys, very kind.
So I don't activate this bandwidth limitation and live in peace. I will let the oscilloscope receive the entire frequency band (200Mhz). Small deviation: while on the Micsig differential probe there is a button to limit the band to 5Mhz, but in this case I believe that for lower signals it is better to activate it, so I have a much cleaner and less noisy signal. Of course if there were peaks every now and then beyond that, I would lose them...

If the DUT is immune to differential signals above 5MHz, then by all means limit the BW to "clean" up the display. If it can be bothered by those signals you want to see them.
You may have answered this question before, but what sort of thigs do you use your scope for? What realm are you working in - audio, radio, digital or all of these?
It's one of those features, such as LF, HF or line triggering on analogue scopes, which sometimes had a bandwidth limiting filter as well. Depending on what you are doing, you might find they are extremely useful, or you never use them. Play around with it and see what it actually does. Bear it in mind and use it when it offers an advantage. You might find there are times when you want to get rid of nuisance noise. I'd guess you won't use it that much.
The problem with this type of thing is that you can forget you've set them, which can cause some head scratching on occasion, until you remember they've been set.Not so much as these settings are clearly displayed in the channel and other tabs.
Default will of course turn all these OFF and return the scope to its factory default state however with these Siglent models you can set a User Default to return the scope to your favoured settings.
If by chance you require a # of preferred settings this can be accomplished saving a Setup file to internal or external memory to be recalled at will.
This offers an unlimited # of custom setup files for specific needs.
Thanks guys, very kind.

There is no blanket answer; yes it's great, always use it, or no it's poison, never use it. It's a feature which may be useful, and to use the scope to best effect you have to be aware of these possibilities and their limitations. Experiment with it, so you know what it does, and use it at need, which I suspect will rarely arise.
Tek 475s have a bandwidth filter; 200 MHz, the default, 100MHz, which gives a cleaner display, and 20MHz which gives a very sharp display. It could be useful in certain circumstances. I think most people learn to live with the slight fuzziness of a Tek 475 and regard it as part of the charm of the instrument.

That's pretty much it.
As with every measurement of anything, think and understand what you want to see and want to avoid seeing. Then choose the instrument settings appropriately.
Sometimes of course, just playing around with different instrument settings can reveal something unexpected. Then you have to figure out whether it is in your experiment, in your measurement technique, and whether it is important or irrelevant. One unexpected example of that can be seen at https://entertaininghacks.wordpress.com/2024/03/16/practical-traps-with-a-one-transistor-audio-amplifier-solderless-breadboards-and-oscilloscopes/
I live very close to an FM radio station and every single measurement I take will be littered with FM radio noise and interference on my Tek 7904. So I have to activate the 20MHz band limit on my 7A26 to get a reasonable display that doesn't have 4 division thick square waves.
If you are trying to ignore external noise such as that, and that external noise impairs your ability to properly take measurements, then you should use the 20MHz bandwidth limit.

What you wrote is clear, but at this point I find it useless to enable a filter to hide something. Why should I hide parts of the signal if they exist? It could probably be useful if I wanted to focus only on signals below 20Mhz, eliminating higher frequency signals from the display. Thank youI live very close to an FM radio station and every single measurement I take will be littered with FM radio noise and interference on my Tek 7904.

Thanks, here is an example that justifies this bandwidth limit. Side note: I didn't think that external waves (not physically measured), could appear on the oscilloscope display. Interesting.
Signal (i.e. relevant) vs noise (i.e. unwanted). In that case it is easy to separate the noise, and filter it out.

Yes, of course, but there are a couple of tings to consider here.
1) The OP is fairly new to the game
2) Even for the experienced, telling what is just noise that can be ignored and what is a noise like signal that indicates a serious problem, can often be difficult to determine.
Just because you see some "fuzz" on your signal does not mean it's time to cripple your scope. At least to me it means it's time to do some detailed investigation as to what is causing that "fuzz". Only once you find it's due to that horrible LED lighting or other such extraneous EMI source do you engage the BW filter. But even then you mgiht be hiding something of interest. IMHO BW filtering is a last resort measure. Not a default.
and having it on doesn't "cripple" a scope.

Hello, I'm Charlotte and I live in Switzerland
I work in the hospital, but my hobby is electronics; i try to repair electrical devices, 99% of the time I don't solve the problem, but that's okay
Women usually read gossip magazines
but there are women who prefer to make love with electrons
My equipment is: soldering station, two multimeters, bench power supply.
I'd like to start a seductive relationship with an oscilloscope..
I don't want to spend too much, but I don't want to buy the worst...
For example the model Rigol ds1052E is ok for beginner woman? or better Rigol ds1202z-e (200mhz) ?
Other brands on these prices?
Do you have any advice for me? i am in your hands...
thanks
Charlotte
OK, so.. Welcome to Electronics.
Now i don't know how being a woman has anything to do with having an Oscilloscope unless you wanted to get it in Pink
with a rainbow unicorn cover.
so you see this...QuoteWomen usually read gossip magazinesIRRELEVANTQuotebut there are women who prefer to make love with electronsand there are women who watch the BOZONE AND THE BEAUTIFUL
...IRRELEVANTQuoteI'd like to start a seductive relationship with an oscilloscope..IRRELEVANT....... Also goes with sayingQuoteFor example the model Rigol ds1052E is ok for beginner woman?so... How many more times are you going to keep saying You're a women ?
We got it, Your name is Charlotte and we made the logical conclusion that you're a womenQuoteDo you have any advice for me? i am in your hands...1. Stop mentioning over and over that you're a women, it's of no consequence
2.QuoteMy equipment is: soldering station, two multimeters, bench power supply.Try mentioning specs and model numbers so we know what you have, as we woudl already logically conclude that you have these things
in some shape or form
3.QuoteI work in the hospital, but my hobby is electronics; i try to repair electrical devices, 99% of the time I don't solve the problem, but that's okayIF YOU LIKE WE CAN JUMP ON A ZOOM CHAT OR SOMETHING and i can help you get that 99% not solving the problem to more like
5% NOT solving
if 99% of the time you are NOT solving the issue , then.. you need some guidance
for me it's more like 98% of the time I AM solving it.
4. OK, so your entire comment is basicallyQuoteI don't want to spend too much, but I don't want to buy the worst...
For example the model Rigol ds1052E is ok for beginner
Classic beginner question...
- First you're confused because you've put yourself in a circular argument... Cheapest possible but not shit. that's not going to happen.
- Secondly DS1052E Should not even be a consideration.
You can pickup a DS1054z for around $300 - $400 thus making this your first logical choice
for around $200 - $300 you can pickup a Hantek DSO2C15
All of these are better than getting a DS1052E
and all these will be brand new with warranty
- What you want to remember is... You don't want to spend money and then have a scope that lags or is slow and then regret your purchase.
so if a decent scope is not in your budget wait till you have the budget.
Fix a few things and make the money to buy the scope, as i said, i can help you get your success rate up, of fixing things.
Basically you're looking for an entry level scope at a decent price that is a decent scope.
Your choice should be Rigol DS1054z
there you go, Now go and buy one
the decision process for this has already been discussed to the Nth degree, the specs, the bang for buck etc etc
the decision has already been made for you as to what is the best for you , Just find where you can find the cheapest 1054z
and get it.. Forget about the 1052e

Pretty straightforward in the Save Recall menu.
But first Default your scope to factory settings then configure it like you prefer, active channels, their positions, probe attenuation, V/div, s/div and so on.
Then in the Save menu select To Default Key.
You have the option to cancel User Default and return to Factory Default.
A couple of screenshots from a 4ch X-E for guidance.
and having it on doesn't "cripple" a scope.It does if it's left on by default as one post had suggested.
I think you and I are in agreement on this. It's an option to clean up the signal when everything else has been considered and eliminated as significant to the measurement of interest. Just wondering if we are getting our sentiment across to the OP.

@BTO, that was completely uncalled for. take a 7 day timeout and calm down.
that was completely uncalled for
Hey Pcprogrammer, Sorry for the misunderstanding mate, i meant nothing by it.
@BTO thanks for clarifying and clearing things up and I appreciate the effort.
I gave you a timeout instead of a flat ban because it seemed like the post was out of anger/frustration and your post history looks nothing like this one here.Please just be a bit more careful about how you word things in future, a lot is lost in text, and how things sound in your head with the context of knowing your thoughts, are often not how they are read and understood by others.
We have pretty strict rules about attacking users and I apologise if I jumped on this a bit too quick.

Hey Pcprogrammer, Sorry for the misunderstanding mate, i meant nothing by it.
For me there was no misunderstanding, it was just a hint to you to pay better attention when posting to something that had already been resolved. I can understand you missing the date of the original post, but the 39 pages long list should have made you wonder.
And it is not me that you need to apologize to for anything that might have seemed anti woman, but to CharlotteSwiss, but she did not responded to your post so might be ok with it either way.
But anyway thanks for your sincerity.
