AD5933 wide range sweep with variable MCLK

Hi all,


I'm trying to conduct measurements from a frequency as low as 20Hz to maximum 125kHz. For this I'm using a variable MCLK. The MCLK is fixed for a certain frequency range as per UG 364. The problem is, between these ranges I am observing erroneous peaks (wrong impedance values) near the MCLK transitions. I have tried adjusting the delay between MCLK transitions, tried to change Number of settling time cycles..but to no avail.


Could anyone give some ideas?


Best regards,
