Acquire multiple channels on a DSO-X-3034A

Hey there,

i am using the 4 analog channel DSO-X-3034A.

I want to acquire a signal on 3 channels. I connect to the oscilloscope via USB using VISA and SCPI-commands in MATLAB.
There is an example how to acquire data from one channel on http://www.mathworks.com/matlabcentral/fileexchange/28887-capturing-a-waveform-from-an-agilent-oscilloscope-over-a-standard-visa-interface

What do i have to take care of if i want to acquire 3 instead of only 1 channel? Will the data of the 3 channels be timesynchronous?

How does the samplerate behave in dependence of the number of samples? The maximum number of samples in the raw mode is 8000000. Is it a third of this value when capturing 3 channels?

Greetings
FloJ
