Hi,I try to run wireless video link but i got this error

niUSRP Fetch Rx Data (CDB).vi<ERR>Overflow: an internal receive buffer has filled before the data could be returned.  Consider reducing the IQ rate, increasing the Fetch rate, or increasing the number of samples per Fetch.

I changed the IQ rate but i still got this error. How can i fix this? Thank you

Hi,

It would be helpful to know a little more about your application in order to investigate this further.  What Sample Width and I/Q rate are you using? Have you been able to run this application before with different settings?  I will see if we are within spec based on the information you can provide.

Hi, 

I got this application from this link-https://decibel.ni.com/content/docs/DOC-22728

IQ Sampling rate=2M

Frequency=1G

Gain=20

I used two different pc for this application.One of them for transmitter,and other one for receiver.

Data source part of  transmitter, there are 4 options.(Text,Image,Video,Random)

There is no problem with text and random(transmitting and receiving).

Error occurs with image and video (transmitting and receiving).
