Rigol HDO1000 and HDO4000 12bit oscilloscopes launched in China
teddychn:
I'm curious about the FFT record length of HDO or MSO5000 scopes. They can reach 1M points in it's datasheet. But in the manual, in fixed FFT point, there are just 65536 point at most. If they have an Auto mode to get 1M FFT point, or I misunderstood something?

The 3-times more expensive 4000 got the same quality like the 1000, same display, same fans, (nearly) same main pcb...
A bit pathetic.

Rigol pathetic ?
This is exactly the same thing Siglent and everyone else are doing in most DSO lines, common HW base with small differentiation and SW upgrades that brings prices to a multiple of the base product.
So what's your point ?
MSO5K with cheapest materials .... :D
MSO5K sells very well and right now Siglent has nothing that could compete, anyway the cheapest DSO materials that I saw in my life were rusty Siglent's chassis that David spotted many times during his teardown.
Dunno if you are conducting a personal crusade against Rigol or if you are part of Siglent marketing system or if you are getting something in exchange, for sure I do not expect an unbiased review from someone that defines Rigol the product under test as "pathetic" in advance.

Oh FFS it seems you and Dave have not been around much as any guillotined galv steel plate will oxidize and I have a Tek TDS2012B right beside me that proudly displays the exact same chassis edge rust in the same way. :horse:
However an early batch of faulty plated steel plate did get through QC many years back and Siglent learnt the lesson to more carefully check products their suppliers send them.

The HDO4204 is only about 50% more expensive than the HDO1204, not three times.
For that difference you get double the sample rate, power analysis functions and smart probe connectors.
Martin72:
Yes that may well be true if I had referred to it, but I did not.
I was talking about the basics, the workmanship and the obviously same components that are used for both model series.
From that point of view, the difference is even greater than three times(699 to 2699).
If we want to cherry pick, then 2.7 times (999 to 2699), from 4-ch to 4-ch, then you´re right, it´s not three times.
When we (as you did) want to compare the feature benefits:

Power analyzer is software only, just like the additional decoder options you can purchase for the 4000 - If they wanted to, the 1000 could have that too.
A "political" decision.
The double sample rate is due to the second chip that was soldered on.
The Smartprobe connectors are also just an additional board, all this does not justify the hefty surcharge and you still have the same quality as the incomparably cheaper 1000 model.
But on the other side, when I get the 4204 for testing, most of the points will be valid also for the 1000(except samplerate/bandwith)*
So I musn´t buy (or loan) a DHO1000 to "know" it.
*( yes I know, it got more memory..But that makes no difference at all.)
