upconversion

[dhiraj03416]

How we can get upcoverted signal using labview 7.1?

for generating up converted signal ,  we used multiplier but it is giving error ?

Can you provide a few more details. It would help if you could attach an example VI?

What are you upconverting, and how?

What kind of error do you get?

Thanks!

from basic signal generation---> sine wave generator--- set frequency to 20 MHZ

                   signal generation---> sine wave generator 1---- set frequency to 5.3 GHz 

we are multiplying both signals using multiplier, then error comes as signal values at different time values "dt".

when both frrequencies are same, there is no error and gives the expected output.

plz provide the required steps for upconverting signals

Hi dheeraj,

Thanks for the post and I hope your well today!

Could you please post the code?

However, I think this error is caused becuase your data points have didn't X scale increments. 

Your data needs to be like 10, 20, 30, and 40 (increments of 10 on the X scale). 

But Im guessing by the error yours is more like 10, 11, 12, ... 39, 40 (increments of 1 on the X scale).

The solution is to Interpolatethe data using the "Interpolate 1D.vi"to produce  data based on increments of 1 (for example). 

Let me know what you think,

Kind Regards,
