Hi all
I'm using NI RFmx Waveform creater to generate 10MHz signal but the signal length is 10ms Thus, it there any way to change the Waveform length to 100us or to create Modulated signal with 100us length.
Thanks all

Frequency * Period = # Cycles. 10,000,000 * 100/1,000,000 = 1000 Cycles.
Change your Waveform to generate (only) 1000 Cycles. You previously were generating (using the same formula) 100,000 Cycles.
Why are you doing RF work if you don't understand Frequency, Time, and Number of Cycles? And I'm not even an Engineer ...

Sorry, this is rude answer.I'm talking about modulated signal which is more complex than what you think.
Thanks

Hi Sattam,
I can see no "rude" answer…
the signal length is 10ms … any way to create Modulated signal with 100us length.
As soon as you tell us how to compress your 10ms signal by a factor of 100 into a 0.1ms signal…
any way to change the Waveform length to 100us
There is a palette with a lot of waveform functions! You can easily create 100 waveforms, each containing a 100µs signal, from your 10ms waveform!

Thanks GerdW for your answer. But the palette can't generate LTE signal.I have NI tool which used to generate different modulated waveforms (LTE, WCDMA, multitones signal) but I don't know how to change the settings for the Waveform length. Thus I'm thinking to generate the 10ms LTE waveform, then filter it to get only 100us.
