Hi,

My customer is using AD9371 with EXT LO function enabled.

They perform the frequency change of AD9371 with EXT LO function enabled according to the RFPLL Frequency change procedure of UG-992. However, if they change the frequency with the UG-992 procedure, the linearity performance of AD9371 is worse than changing the frequency by performing a full initialization.

Could you please provide an optimal frequency change procedure when using EXT LO ?

Thanks.
