NI 5772 spec

[hululu]

Hi, There,

I am using NI 5772 and found there are two different numbers on the specification.

One is absolution max voltage +/-30 VDC  +21 dbm(7.1v Vpp) and another one is full scale input 2Vpp or 4 Vpp.

What is the difference between these two numbers? That 30 VDC is power supplies voltage, right?  There two Vpps. Could I select one of them and how? 

Thanks

Exceeding the absolute maximum can damage the components.

Exceeding the full scale input does not damage the components.

One place to find out more is in the datasheets of ICs from Analog Devices, Texas Instruments, Maxim, etc.
