fetch IQ

[Sharmi]

Hi,

I am using niRFSA Fetch IQ vi to continuously acquire data in PXI ( Ia m using 5663 to receive and 5673 to transmit data). 

This vi can fetch only one record at a time and when I view the data in time domain I can only see the data for 0.2 sec. I want to increase the time window to 10 sec.

Can anybody please tell me how to do this?

I have attached the screenshot.

Thanks so much,

Sharmi

Hi Sharmi,

Are you trying to change the window size or the resolution bandwidth? If you just want to change the window size, you can double click on the 0.2 and retype a new value. If you want to change the size of your acquisition, you would use the Resolution Bandwidth Property. You can use the NI RF Vector Signal Analyzers Help to find out more information on the property node itself. Here is a screenshot of the definition of that property in the help.
