Wideband 2-channel universal filter
The 3620 series is a two-channel frequency-variable filter that allows you to freely set the cutoff frequency. You can choose from four types of lineups based on the attenuation slope and cutoff frequency range. It operates independently in two channels, allowing you to switch between low-pass, high-pass, band-pass, and band-elimination modes, and it also supports cascading of the two channels.

basic information
■High Resolution (3624/3625) The variable range of the cutoff frequency is from 0.01Hz to 159.9kHz, and it can be set with high resolution of 3 1/2 digits (1 to 1599) within that range, covering most applications in the low-frequency domain, including acoustics and vibrations. ■Wide Bandwidth (3627/3628) The cutoff frequency setting range is from 1Hz to 1.59MHz, providing a wide bandwidth, and it can be set with high resolution of 2 1/2 digits (1 to 159). It enables signal processing across a broad range from audio frequencies to ultrasonic frequencies. (The maximum frequency for HPF and BEF is 500kHz) ■Rich Functions With two independent channels, each can be switched to low-pass maximum flat, low-pass phase linear, high-pass (maximum flat), band-pass (1/3 octBW), or band-elimination. Furthermore, the two channels can be connected in series, allowing for double the attenuation slope with the same settings on both channels, creating a wide-band band-pass filter with low-pass and high-pass.
