AFAIK, no market sell on china right now .
But there's a promotion going on Siglent china website that seems 10% off the 1000X HD by signing up for the trial, till the end of June. The 2000X HD series is also carrying promotions at the same time.
By just comparing the datasheet, the difference between 1000X HD and 2000X HD are:
Sample rate:
1000XHD has total of 1G sampling rate capacity(1G for 1CH, 500M for 2CH, 250M for 4CH),
2000XHD has total of 4G sampling rate capacity(2G for 2CH, 1G for 4CH).
Memory depth:
1000XHD has 100Mpts interleaved or 100Mpts per channel (To be clarified) ,
2000XHD has 100Mpts per channel,
Waveform capture rate:
1000XHD is 400,000 wfm/s on Sequence mode,
2000XHD is 500,000 wfm/s on Sequence mode,
Peak detection:
1000XHD 4ns,
2000XHD 1ns,
Bandwidth flatness: slightly worse on 1000X HD,
AC coupling cutoff frequency:
1000XHD 2Hz,
2000XHD 5Hz,
SFDR:
1000XHD ≥ 35dB,
2000XHD ≥ 45dB,
Channel isolation:
1000XHD > 40dB,
2000XHD > 70dB,
Horizon DIV:
1000XHD 2ns,
2000XHD 500ps/1ns,
Time Base Accuracy:
1000XHD ± 25ppm
2000XHD ± 2ppm
Trigger:
2000XHD has more trigger options, plus touch screen area trigger,
Waveform histogram:
1000XHD no waveform histogram,
Math channel:
1000XHD has 4 Math channels!!!!
2000XHD has 2 Math channels,
Logic analyzer:
1000XHD external SBUS device, 16ch 1GSa/s, 10 Mpts/ch,
2000XHD internal option, 16ch 500MSa/s, 50 Mpts/ch,
Waveform generator:
1000XHD 25MHz external USB device,
2000XHD 25MHz internal option,
We can definitely tell that the 1000XHD are significantly down spec in many ways, but for hobby or even general development use, it's quite adequate.
It's happy to see that 1000XHD has the same 0.5%DC accuracy from 2000XHD, the standard Bode plot test(which is optional on 2000X+), also the 4 math channels!!
Personally, the only complaint I have is the 4-channel model still shares that 1G sampling capacity, which means only 250M for full channel use. But still very attractive considering its price. I have almost put the trigger on RIGOL DHO1000 last year, but has always been put off by its toy-like appearance and design. Thanks for siglent now I can take this 1000X HD instead
