FFS.. just think about when you use the record length... and when you don't
bullshit, you can select on Owon between 1k/10k/100k/1M/10M, all of them sampled with 1GSs
where ATTEN CAL have only 40k sampled with 1GSs - or if you need memory 2M (on CML model)
sampled with 500MSs ... you see now the diff.
There is no single reason to chose ADS1102CAL, not from ADC point of view, not FPGA, not SoC, never ever memory
and never ever display .. did i forgot something? Yeah, VGA out, less waveform distortion, higher wfrm/s.
The only reason might be price ... but buy cheap means buy twice.
EDIT: oh wait, the ugly red color on Owon sucks, so you ahve two reason to chose ATTEN. But there will be smart
people knowing how to use hex editor and the red color will be gone.
