Group delay measurement error with 75 ohm setup in ENA series analyzers

Whenever I use E5071b analyzer for a 75 ohm set up , my group delay shows a small pulse like measurement error exactly at 2250 MHz for all type of DUTs. I checked with all type of analyzers used, but i keep on getting a small pulse like measurement error in ENA E5071B series analyzers. This measurement error is solved while using PNA-X series analyzers completely. What may be the cause for this type of issue in ENA series?
