The 3624 Dual Channel Programmable filter has an extremely wide frequency range with cutoff frequency 0.01Hz to 159.9kHz 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, and phase linear response is also avalable in the LPF mode.
