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:
(Edit for 2024 newer Black appearance version )
Sample rate:
1000XHD has total of 1x2G sampling rate capacity(2G for 1CH, 1G for 2CH, 500M for 4CH),
2000XHD has total of 2x2G sampling rate capacity(2G interleaved, 1G non-interleaved).
Memory depth:
1000XHD has 100Mpts interleaved, 50Mpts for 2CH, 25Mpts for 4CH
2000XHD has 200Mpts interleaved, 100Mpts non-interleaved,
Waveform capture rate:
1000XHD is 120,000 wfm/s Normal mode; 500,000 wfm/s on Sequence mode,
2000XHD is 100,000 wfm/s Normal mode; 500,000 wfm/s on Sequence mode,
Peak detection:
1000XHD 2ns,
2000XHD 1ns,
Bandwidth flatness:
slightly worse on 1000X HD,
AC coupling cutoff frequency:
1000XHD 2Hz,
2000XHD 5Hz,
SFDR:
1000XHD ≥ 35dBc,
2000XHD ≥ 45dBc,
Channel isolation:
1000XHD > 40dBc,
2000XHD > 70dBc,
minimum Horizon DIV:
1000XHD 1ns,
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,
2000XHD has waveform histogram,
Math channel:
1000XHD has 4 Math channels,
2000XHD has 4 Math channels,
Mask test speed:
1000XHD 80,000 frames/s,
2000XHD 14,000 frames/s,
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 2G sampling capacity, which means only 500M for full channel use. But still very attractive considering its price.
