The 3624/3625/3627/3628 Dual channel Programmable filter have an extremely wide frequency range with cutoff frequency 0.01Hz to 1.59MHz for LPF, HPE, BPF and BEF(option).The use of the 3620 series is not limited to electronics; it also covers a wide field of physical experiments, studies on physical properties and other related areas. Its attenuation slope is 24dB/oct(3624/3627) and 48dB/oct(3625/3628), and phase linear response is also avalable in the LPF mode.
