I upgraded my PXI system from the PXI-5402 waveform generator to the new dual channel AWG PXIe-5413. Unfortunately I discovered that the DC offset for this last is only 50% of amplitude despite a more wide range of the PXI-5402:
I'm really surprised because it's a big limitation. For example I need a sine wave of 20 mV amplitude and a DC offset ranging from 0 to 1V. With PXI-5402 it's a simple task using standard waveform settings but with PXIe-5413 probably I have to move to arbitrary settings and create the offset digitally with "niFgen Create Waveform".
Any suggestion is appreciated!
Solved! Go to Solution.
unfortunately your analysis is correct. With the 5413 you can't generate a 20mV amplitude sine wave with 1 V offset. You must use the arbitrary generation to achieve that goal.
thanks for the reply despite no good news 😉
So I can do only this I suppose:
For shure it'll be noiser respect the full analog offset of PXI-5402.
If you have other suggestion in mind ....i'm a big ear.
