# 11668A Agilent Filter Used

**Additional Features:**

-   Reduced modulator drive feedthrough from 8 mV to 1 mV
-   Eliminates the need for passive measurements

Use of the Agilent 11668A, placed after the Agilent 11668B, reduces the modulator drive feedthrough from 8 mV to 1 mV and prevents possible amplifier saturation. Use of the Agilent 11668A filter is not necessary for passive measurements since the feedthrough from the Agilent 11665B is -65 dBm and causes no degradation in system performance.
