[ Implementing a Phase Shift block ]

Hi all,

For finding the time lag between two synchronized signals, I have
recorded
their maximum correlation value and the time-delay (the difference
between
the index where their first zero crossing appeared) between the signals.
Have attached those values (for different runs) that I noted down.

I couldn’t find any particular relationship in the data recorded. Can I
know how to use these values to find the delay value (in time domain),
which can be used in the Delay block in the GRC?

Thanks.

Forgot to mention the parameters

Signal generator freq - 400.01M
USRP source (2 in number) freq - 400M
Sampling rate - 2M
Power level in Signal generator : -5dB
Gain in USRP source - 0dB

Note: USRPs were synchronized using MIMO cable
