Agilent Technologies, Inc. 11668A High Pass Filter
Feature:
Type: Filters
Frequency: 50MHz
The HP 11668A high pass filter accessory is recommended when making measurements on active devices that have gain
below 50 MHz. Use of the HP 11668A, placed after the HP 11668B, reduces the modulator drive feedthrough from 8 mV to
1 mV and prevents possible amplifier saturation. Use of the HP 11668A filter is not necessary for passive measurements
since the feedthrough from the HP 11665B is -65 dBm and causes no degradation in system performance.
Reduced modulator drive feedthrough from 8 mV to 1 mV
Eliminates the need for passive measurements
