PXI 5122 : range selection

[Frederic - Munchen]

I have the PXI 5122 and I want to adjust the range under 50 ohms input with the niScope VI : Configure Vertical. I´ve just seen that in the detailed spec. only the values 0,2 - 0,4 - 1 - 2 - 4 volts seem to be allowed, although I can use 10 or 9,5 Volts with an example of niScope (niScope EX Mesurement Library.vi). If you enter 0,5V for the range, is it rounded to 1V ?
So can you tell me :
- what is the real Full Scale for an input of 50ohm ?
- are there pre defined values for the full scale or can I select whatever I want ?

Thanks

In the 50 Ohm path of the PXI-5122, the programmable full scale input ranges are the following (per the NI 5122 Specifications page 2):
0.2
0.4
1
2
4
10

If you enter a value that is not exactly one of the values listed above, it is coerced up to the nearest valid rage. For example, if you enter 0.5V for the range, it will be rounded up to 1V.
