ValueTronics International, Inc. Filter 11668A

The 11668A is a Filter from Agilent. Electronic filters perform a variety of signal-processing functions with the purpose of removing a signal’s unwanted frequency components, enhance desired ones, or both. There are many types of electronic test equipment filters, including those that are passive, active, analog, digital, low pass, high pass, linear, and nonlinear. Linear filters are the most commonly used for most electronic equipment applications. 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.
