If you order a new 200MPH Porsche 911 Twin Turbo you expect the tires to be better rated than 100MPH!! The factory supplies tires that are rated for 200MPH, if you want to change them you certainly can, but they are rated for 200MPH, and you paid for those 200MPH tires
Best,
You chose the wrong example.
If you want to talk about precision on numbers, you must avoid talking about a brand that belongs to the Volkwagen group
Not the wrong example, Porsche just belongs to a larger group but doesn't convey they are performing or even held to the Volkswagen metrics which I do consider questionable, same goes for Audi. The Porsche 911 is recognized worldwide as the benchmark for all sports cars, why we have two (BTW the red 911 is a 993 model which is the last of the air cooled 911s, and worth more today than when purchased new in 1996!!)
LeCroy belongs to Teledyne, but they still perform to their own established metrics!! I mean what does Teledyne know about oscilloscopes??
Best,
Regardless of wrong or right cheapest probes delivered, it´s a strange policy from siglent, giving the cheapest probes they can get to this not-so-cheap-anymore-scope.
I would expect that for their very low price models, not for this one.
When rigol could offer 350Mhz probes even with their 70Mhz model of the 5000 series, which costs nearly 500 bucks less...
When Lecroy doesn´t have a problem to pack their 350Mhz scope with 4 500Mhz probes, where each of them will costs extremely when buying separately..
...It tells me, that probes itselfs will cost not much for rigol or lecroy.
But for siglent ?
What will happen, when I´m upgrading the bandwith official ?
Do I get new probes with the license key too ?
I think not..
Here is @Performa01 made test result.. if bit stretch things... what is probe freq what Siglent offer, even with 70MHz model (examaple with SDS2074XPlus). Do not read probe text.. it do not matter. Reality matters.
Regardless of wrong or right cheapest probes delivered, it´s a strange policy from siglent,It's not policy but nonadherence to the official datasheet.
Let me say this again....anyone that receives PP510 probes with a new SDS2104X Plus instead of the specified PP215 probes contact your supplier to have them replaced.

^^^ What tautech said. ^^^
tequipment.net indicated they were recently notified by the mfr. that incorrect probes were included with the Plus model of this scope and that Siglent would be replacing these directly (with PP215's). tequipment is sending Siglent a list of affected customers today and also gave me the phone number for Siglent (877 515-5551) in case I wanted to contact them myself.

Not identical. Close, but not identical. Look especially at the lower end of the frequency range, and you'll see the two deviating from each other by about 1 dB. Maybe that's close enough to be regarded as "identical"...
Honestly, why should any of this be a surprise? You're likely to get better returns from mass manufacturing if you make both probes using the same materials and techniques, and then separate them on the basis of the result of quality checks, than by manufacturing them using different materials and/or techniques.
New owner of a SDS2104X+ here. I also received 4x PP510 probes, going to e-mail the seller now. [...]

Reality matters.What reality? I looked up the thread; Performa01's measurements of the 100MHz and 200MHz Siglent probes show identical results even though they have different specifications. Something must be wrong. I already noted in that thread that probes should be measured using a source impedance of 25 Ohm. Performa01 never acknowledged that he did that. Another problem is that he used a 200MHz oscilloscope. The total risetime of the system is roughly sqrt (rise_time_probe^2 + rise_time_scope ^2) (See Keysight appnote 5988-8008EN). In the end the difference between a 100MHz and 200MHz probe is much smaller than you expect when you use a 200MHz oscilloscope because the risetime (bandwidth) of the oscilloscope influences the bandwidth as well. The difference between using a 100MHz probe versus a 200MHz probe results in a 90 MHz and a 140MHz bandwidth (50MHz difference instead of the expected 100MHz!). A much better measurement approach would be to use a dedicated probe testing rig with a high impedance, high bandwidth buffer amplifier which drives a 50 Ohm >1GHz bandwidth oscilloscope input. This way you reduce the effects of the oscilloscope.

What probes are included from the factory with this machine?
- SDS2104X+: 4x PP215 - Correct?
- SDS2204X+: 4x PP430 ?
- SDS2354X+: 4x PP430 ?
From the datasheet P3:
Probe (standard)
SDS2354X Plus
SP2035A, 350 MHz, 1 probe supplied for each channel
SDS2204X Plus, SDS2104X Plus
PP215, 200 MHz, 1 probe supplied for each channel

But you're right, the Beetle is a fast car even if it has the engine in the wrong place
Oddly enough I just bought a SDS2204X Plus and it came with 4x SP2035, 350 MHz probes in the box.
… if you build a passive probe properly, with the correct HF compensation for the scope input it's intended to be used with (or adjustable HF compensation like e.g. the TesTec TT-MF312), then you can expect a probe bandwidth of several hundred MHz and you would have to deliberately add internal filtering to limit the bandwidth to e.g. 100 MHz.
specifications just tell you what the manufacturer is willing to guarantee;
"I want to return my scope, it doesn´t have the bandwith like the scope my friend got, only 150Mhz instead of 180Mhz and he got the same model !
Sir, you bought a 100Mhz Version..."
