Hi, this is my first question in Keysight community. I have met a problem in LTE demodulation:
I have made a 20ms LTE 20MHz signal (sample frequency is 61.44MHz) in SystemVue. To verify the finite word length effect, I send the quantized data to VSA by building a SystemVue simulation system.
When I demodulate the data in VSA, I can get the constellation and EVM, but the whole time length is just 3ms, is it right?
And I download the data in the time domain when the Span bandwidth is 48MHz. Unfortunately, any output point cannot be found in the original series. ps: the input data length is 1228800, the data from the VSA download length is 184320 (3:20).
I want to know HOW TO GET THE COMPLETE TIME LENGTH LTE SIGNAL.
thanks for your help!!!!
