The front panel is inspired by Rigol DS2000 and Agilent (=Keysight) DSOX2000. I like it.
This ZDS2022 scope might be available only in China.
How do they achive the 6 seconds boot up time?

Seems to be expensive at $1600 for what it is.

[Hydrawerk]

The back is inspired by Rigol DS4000. I wonder if they really have only a 30 Watt power supply.

[Guni]

Funny.
Rigol box+ Agilent panel inspired. Picture is not a real just a render. Scale of BNC connectors looks wrong - too small.

[FrankenPC]

Ughh.  The firmware is so damn buggy on these types of scopes.  It's almost unbearable to use.  If they guaranteed that they had an internal continuous dev model on the firmware, I might go for it.  But my experience is these devices are cranked out and basically forgotten.

I'll tell you what...the first company to put out OK hardware with open sourced firmware...I'd go hog wild with that.  I'd pay extra for that.

eagle vie ?

It's probably eagle view, the stylized electric bolt forms the W.

If it;s only for the Chinese market, it's gonna be a runner

It's certainly a much better looking front panel than the crap Rigol has been spewing onto their latest scopes.

Remember that you are looking at computer rendering. Look at actual pictures in the first link and you will see that they are not much better than Rigol.

I don't think this:



Looks better than:



In fact, I think it looks much worse?

[Hydrawerk]

Yes, the ZDS2022's rotary knobs seem to be too small.

Any news?

They are available for sale, but the aren't cheap https://world.tmall.com/item/43297144205.htm?spm=a312a.7728556.0.0.i9tjlJ&id=43297144205&skuId=80988978306

If it does what it promises and has no severe bugs then the price certainly seems like a good deal to me. It's a pity products like these don't find their way outside Asia because I'd like to see a review of it.

How do they achive the 6 seconds boot up time?

Not too hard. Good enough CPU, very basic embedded OS, not doing extensive self-cal every boot time (but store the constants), offloading FPGA configuration to a dedicated device instead of loading from the main CPU or using nonvolatile FPGA.

The older iwatsu scopes (Lecroy Wavejet) took around 3 seconds from pressing the button to first trigger.

Boot time is largely affected by how fast the boot medium is. Plain Linux can start within a few seconds from a Sata SSD.

They also have a 4-channel model in that series.

Here is a nice render scene

The number of FFT points seems very high!

How come that a company coming from nowhere can reach such a good FFT implementation,
while Rigol, Siglent, GW-Instek with years of experience do not even come close in the number of FFT points?

Where is the catch? =)

[ataradov]

They may have more computing power on board. The scope is 2-4 times more expensive than Rigol and Siglent counterparts. Hopefully some of that went into the hardware, not just the profit margin.

[pascal_sweden]

How can we get this scope in the hands of Dave Jones for an in-depth review?

GW Instek has 1Mpts FFT which is already a lot (certainly compared to 1k for Siglent and -since recent- 16k for Rigol) but the 4MPts the ZDS2000 offers is more ofcourse. My guess is the ZDS2000 is also based on the Xilinx Zync (multi core ARM + FPGA) platform.

ZLG has been around longer than Rigol or Siglent.

The only problem with that, you cannot buy this from any reputable distributor outside of China.
