SDS2000X Plus ?
It is high compared to some other models but matches the SDS7000A spec.

No, 80,000 is what the docs say for the SDS800XHD. I find it hard to believe that a hardware accelerated function would be highest in the lowest model. That's not how hardware planning usually works. I also assume it was supposed to say 8,000.

SDS8204X HD  SDS824X HD measured Mask test max (average) is around 82400 test/s

(Measured Fail pulses from Pass/Fail output BNC frequency with HP53131A  using 1s gate. Up to max Peak speed is 89000 tests/s, measured (pass/fail pulses interval) using SDS3000X HD

There need note that acquisition works in burst mode. In this particular case 1 burst period was 34.7ms including around 2.6ms pause)

Signal in to Ch1 10MHz and Mask test so that test fail in every acquisition.

voltsandjolts thanks for the model correction

rf-loop thanks for the testing

Any ideas on why the 824X HD has such strong peformance vs the the 2000X HD and 3000X HD?


SDS800X HD and SDS1000X HD
Mask test speed  Up to 80,000 frames/s
SDS2000X HD
Mask test speed  Up to 14,000 frames/s
SDS3000X HD

So you're saying the typo is the higher models instead of the 800 series?

Kindly, Please, don't put words in my mouth that I haven't said. I think the straw puppet theater belongs somewhere else - or not any - in my opinion, it is not suitable for anything.
 ;) :)   


SDS3000X HD max speed is stated as up to 28000/s and it is true least at current FW 1.0.3.3.

I also wonder where from come suspect or claim that it is not true.
Later when/if I have idle free time to take SDS2kXHD on board (if need) I can also check it.

With this test I measured ~28300 fail pulses/s from Aux BNC when test was continuously running as in image below.
