HMC835 loop bandwidth

Hello-

We are using the HMC835 to create a carrier between 2-4 GHz. Then we inject a modulation signal at the external loop filter.The modulation signal is between 10-100 MHz baud rate and 100's of MHz frequency deviation. But when we perform manual calibration, to  achieve quick carrier settling, the modulation goes away. Can you explain any difference in the use of the loop filter between manual and automatic calibration?

Thanks and Best Regards,
