Connected to the DS2000, i got 8 screen updates per sec., see picture.
I lookd into my network sniffer, and checked the time between the ethernet frames,
it was on the DS2000 much faster exchange rate then on the 1000.
The ds1000 is slow in the tcp/ip. Also Visa uses such small packets in ethernet,
max packet size i saw was about 70 to 80 bytes per frame.
In my case on the DS1000 , 2 channels about 2 screens per sec, on the DS2000, 8 Scr/s
Happy, the DS1000 also has a command for transferring a complete screen, maybe that will be fast.
