Acquisition Data Amplitude Varying...
I am transmitting a constant amplitude I/Q modulated DSSS signal using RFSG-5670.
While receiving this transmitted DSSS signal using RFSA-5660.I am using the normal RFSA Programming flow to control my acquisition. Using Reference nodes, I set my other NI-Scope parameters as required.
Other settings for NI-SCOPE and RFSA being set at default levels, With each acquisition of data,
I find that I/Q data varies in amplitude in a random manner. Also, Signal levels are significantly high when they have to be zero.
Any idea why this is happening so ???
Is it improper setting of Trigger Levels, Ref.Positions, etc..
Can anybody help me regarding this....
Thanks for your help
