When ADRV9001 calculates the default values, it utilizes the transmit/receive propagation delay internally characterized for different
profiles. User should measure the propagation delay in their application to help determine all the required timing parameters. During the
measurement, user could set all the timing parameters to be the default values for simplification and also it is important to use the same
profile and configurations as the actual application being deployed.
After calculating all the timing parameters required by ADRV9001, user could configure them through TES as shown in Figure 68.
As shown in Figure 68, only relevant channels are enabled for timing parameters configuration. User should enter all the values in ns.
The propagation delay is a helper parameter, which is not needed by ADRV9001. It helps to set other timing parameters ADRV9001
requires.

91 ms/scaleFactor Default = min
91 ms/scaleFactor Default = min
Not needed if not controlling LNA power
91 ms/scaleFactor Default = min
Can increase if performance degradation
is observed and the channel is receiving
for some time before the start of the
actual frame
(Forced to be 0 currently by ADRV9001)
91 ms/scaleFactor Default = min
Can increase if performance degradation
is observed and the channel is receiving
for some time after the end of the actual
frame. Can still be used if not controlling
LNA power down.
