Right now, I see one of the vendors on eBay selling MicSig 100MHz 1400V differential probes has them for $120:

I just ordered one for $115 (best offer). Hopefully the thing works well. Thanks for the ebay idea, saved me $45 vs. the same thing I was looking at on Amazon.
Sure thing. Was that from the same vendor that had it discounted to $119 (looks like it went up a bit)? It sure is a good price. I'm tempted to get one, but I already have an HVP-70 (got it before Micsig released theirs).
$115 !? That's a great price. There are a few review threads of it floating around here somewhere. It's probably more like a 60MHz probe, but for the price, it's a nice little unit.
But then, there is possible also things what user can not think before he find how useful some features are
It's not "unknown" at all. The Rigol does all calculations, serial decodes, etc., based on the block of 1200 samples that's currently displayed on screen (squished into 600 pixels). You want a better answer? Zoom in on the area of interest (or press 'auto' ).
1) PS: Any RMS calculation of non-bandwidth-limited white noise is always a bit 'suspicious' and a very suspect way to demonstrate a 'scopes supposed superiority. The VPP number is the one to focus on.
2) 1.3mV of noise @1GHz with the probe in 1x mode? Turn on the bandwidth limiter, that's what it's for.
Understanding Noise and How it Should Be Measured:
Random noise, sometimes referred to as white noise, is theoretically unbounded and exhibits a Gaussian distribution. Unbounded simply means that because of the random nature
of noise, the more data you collect in noise characterization measurements, the higher the peak-to-peak excursions will grow. For this reason, random phenomenon such as vertical noise and random jitter should be measured and specified as an RMS (one standard deviation) value.
Turn on the bandwidth limiter, that's what it's for.
It doesn't matter whether you turn the BW limit on or off because the Rigol 1000Z is noisy like hell. The more recent oscilloscopes from GW Instek, MicSig and Siglent use a very low noise analog front-end and ADC (IIRC they all use the same so their performance when it comes to noise is comparable).

Do you think that's good to use in general for audio stuff? Is there any reason I would need to see anything above 20Mhz probing a tube amp? Is that a dumb question?
Siglent what also can calculate RMS and it do it right.
Different series, different processor, older model.
Good to see you watching videos about Siglents.
The only thing 'suspicious' about those measurements was subtracting 3dB from the Siglent's noise level just because you felt like it.
Onlöy what I tell was that BW difference is 1:2 and you know (or then you do not know) where from this 3dB come.
Rigol will soon have their new ASIC in a low-end model, so... meh.

Do you have any specifics about this?
Hopefully they have a new design for the front panel too. I hate the arbitrary, asymmetrical goofy outlines. Looks better than Instek, but that's a low bar.
It also seems like only the SDS1004X-E series is relatively new from Siglent, and everything higher-end is trailing behind. I like the look, larger screens, and individual vertical controls of some of the higher-end Siglent models. But why would I spend 4 times as much money for less scope ability than 1104X-E? Yes, I know there's higher bandwidth and sampling available, but the rest of the scope needs to catch up.
Obviously not. No company leaks information like that.

Meh. You probably wouldn't notice it after a day of use.
The situation should flip around now the respective new models have been launched. Let's see if Rigol startes dropping some hints a few weeks from now.
(to make anybody who's thinking of going from DS1000Z to SDS1000X-E wait a while before deciding )
I had the DS1054Z for 3 weeks. I noticed it every single time I looked at it. I hated the design. It annoys me. My primary job is web/graphic design; I can't help but notice that stuff. It drives me batty when designs are that bad. The Instek also seems like a better choice than the 1054Z, but I simply won't put it on my bench because I can't look at it.

Is the Siglent really that much better?
Maybe you should get a Micsig tBook or something.
I assume you won't want the rubber bumper frame but you can also use it via your phone.
