3660A NF Corporation Filter
The 3660A is a Filter from NF Corporation. 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.

The NF Corporation 3660A is a programmable cut-off frequency lowpass filter with very high frequency range, max.100 MHz. Since the roll-off of the lowpass filter is as steep as 48dB/oct, cut-off frequency can be set to required frequency with 2-digits resolution.
