For a price of up to 2kz, you have two options: either SDS1102x or DS1054z I have both and tell you that everyone is OK and everyone has something better than the other.
I bought the Rigola for PLN 1470 as a curiosity, because it was an opportunity. I haven't unlocked yet but ... I'm positively surprised. First of all, I was positively surprised by the probes in the set. Almost perfect as if they were replaceable needles. The oscilloscope has one downside and the menu is a nightmare.
And yes you can bid this has this this has that. The advantage is also the input capacitance R is 13pF, S is 18pF here again there are disadvantages. The S has a larger work screen for observing the waveform and a nice menu, a rigol nightmare menu and a smaller screen which makes it colorful and fun. Graphically, rigol beats the siglent in the waveform display. Ergonomic siglent rigola. Rigola disadvantage is a poor time base ending at 5ns which at 100MHz is a bid and the siglent is 2nS.
Here, one has two channels, the other four, but when working with four channels, it is too colorful and crowded on the screen.
Now there is a newer model of the SDS1102x siglent
In the foreground, the probes are crap.
The quality of workmanship here, we need to mention only the rigol encoders a bit better, only a bit better.
How would I take rigola. The cheapest option and good probes. Save it for 30 hours according to the unlocked options and how to unlock it and that's it.
In mine, there was a problem with channel 4 at 1mV offset, but auto calibration eliminated it. Sometimes, during AUTO, he could turn on the 4th channel, despite the fact that there was a signal on 1 and the rest turned off.
The basic question is what the oscilloscope is for. The application determines which features should be paid more attention, and which slightly less.
The Axiomet is a slightly older design, similar to the previous generation Rigola, which is now being withdrawn: DS1102E
The Rigol DS1054Z has good input circuits and can handle synchronization up to 400MHz. Here a photo of what it looks like (the equipment is obviously not locked)
@NDN Warsaw 400MHz, but with what amplitude drop ... And MHz, not MHZ.
With a big one, of course. After all, this is a 100 MHz oscilloscope, not 400 MHz. The point is that rarely any 100 MHz oscilloscope will display this high frequency waveform. For example, my old Tek 2220 with the 60 MHz band only displays up to max. 180 MHz, and where 200, 300 or 400 MHz. Above 180 MHz, it is just a horizontal line, which is impossible to read the waveform. For me, as an amateur radio, it is a decent feature when I can check the waveform at the generator output and the exact amplitude measurement is a secondary matter. Therefore, for amateurs, the Rigol 1054z is a very good and cheap solution.
@NDN Warszawa 400MHz, but with what amplitude drop ...
If I find it, I will put the damping characteristics both in the 50MHz version and after unlocking to 100MHz. Once, we took the characteristics off in the calibration laboratory. Therefore, I wrote only about 400MHz waveform synchronization - the attenuation significantly exceeds 3dB.

I'm already correcting the typo

Here I think it was about the lack of synchronization. For example, the Siglent SDS1102X-E with the 200MHz band stops synchronizing already after approx. 250MHz and we will not see even a sine wave with a frequency of 300MHz there - just some garbage on the screen. The Rigol DS4024 (also 200MHz, but a 4GSa / s converter) can now synchronize the 1GHz waveform. So far, Rigol has the greatest opportunities among Chinese manufacturers. For example, he designed a new acquisition system that allows to build a 4GHz oscilloscope.

Rigol has built a prototype scope based on Phoenix and Ultravision II, boasting a 4GHz bandwidth, 20GSa / s real-time sample rate and 1 billion point memory depth.
Returning, however, to the beginning of the topic - the most important question is the use of the oscilloscope. I often meet that a subordinate feature - sometimes, not even mentioned in catalog cards turns out to be crucial when choosing a specific type. For example, for the detection of dips in power systems, the possibility of memory segmentation and the real-time clock (allowing the time identification of captured segments) will be much more important than bandwidth, sampling rate or bus decoding. The DS1054Z will be insufficient for this application. You have to reach for the DS2000 series or the Siglenta SDS1000X that already have a watch. Then you can fasten the oscilloscope for up to a week and then analyze the stored results. For amateur radio - frequency response will be the most important.
the oscilloscope will show a sine wave correctly, not a distorted waveform.
It does not matter for me. The most viewed signal is the sine wave, especially in radio and ham radio. Everyone will show up to 1000 MHz correctly, and above I have a "free" bonus, I can watch up to 400 MHz sine. I'm very happy about this. There was no such possibility on my previous ones.
The discussion revolves around the comparison of two oscilloscopes: the RIGOL DS1054Z and the AXIOMET AX-DS1100CFM, both priced under PLN 2,000. Users highlight the RIGOL DS1054Z's advantages, including its four channels, 12 Mpt memory, and lower price, while noting that it can potentially be unlocked to 100MHz bandwidth. However, some users criticize its complex menu system and limited time base. The AXIOMET model is recognized for its 100MHz bandwidth but is considered an older design. The choice between the two oscilloscopes largely depends on the intended application, with the RIGOL being favored for amateur radio use due to its good input circuits and synchronization capabilities. Users also discuss the importance of waveform display quality and the ability to handle high-frequency signals. Summary generated by the language model.
