No, it's a single ADC as well in the DHO1000.

Looks like a downgrade from the DHO1000 series: Half the memory size (25 MPts standard, 50 optional) and a reduced waveform capture rate (max. 30k/s regular mode, 500k/s UltraAquire mode).

My guess is that they have taken the 800/900 FPGA and memory and put it in the DHO1000 package.

But then how do they get 2 GSa/s out of that? Unless the 800/900 are artificially throttled...

If DHO 1K had 2 ADC's would have been a killer for his big brother DHO 4K. It can be transformed through vendor.bin method into DHO 4000 model, but with one ADC it is not too usefull as the software expect 2 ADC.
