Dual Channel Programmable Filter

3624/3625/3627/3628

3628

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.

Wide Range Decade Filter

FV-628B

		Wide cutoff frequency range: LPF 1Hz to 10MHz, HPF 1Hz to 3MHz, and BPF combination of LPF and HPF
		LPF can be switched over maximum flatness and phase linear responses.

HF Programmable Lowpass Filter

3660A

The 3660A is a programmable cut-off frequency lowpass filter with very high frequency range, max.100MHz. 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.			Variable cut-off frequency : 1MHz to 100MHz Max flat/phase linear switch
			Roll-off : 48dB/oct
			Group delay ripple : 10ns or less
			Available for Highpass filter 10Hz to 100kHz

CD Player Evaluating Filter

3346A

The 3346A enables an effective measuring of signal/noise ratio, dynamic range, harmonic distortion ratio, channel separation and cross modulation distortion rartio prescribed by the measuring standard for CD Player. (EIAJ CP-307)

Mix-tape Band-pass Filter

DV-12

The DV-12 is a bandpass filter with a center frequency which is selectable over eight points. Combined with a mix-tape where several frequencies' sinewaves are multirecorded, this model enables adjustment and inspection of a cassette tape recorder.

Multichannel Filter (built-in module)

Please refer to the page of Function Modules about built-in modules.

Resister Tunable Filter
The Resister Tunable Filter is a CR active filter which can control the cut-off (or center) frequency with externally connected resistors.
It can be used by having module-type filters built-in.

Model	Built-in modules	Filter characteristics	Number of channels
3314	HR series	Lowpass/Highpass/Bandpass	4 channels max.
3315	SR or SRA series	Lowpass/Highpass/Bandpa ss/Bandelimination	8 channels max.
3316	RT series	Lowpass/Bandpass	8 channels max.

Voltage Tunable Filter
The Voltage Tunable Filter features frequency control by means of external applied voltage.
The filters of VT series is built-in as option.

Model	Built-in modules	Filter characteristics	Number of channels
3334	VT series	Lowpass/Highpass/Bandpass	2 channels max.

Programmable Filter
Cut-off frequency is controlled with an external logic signal.
DT-5FL or DT-6FL is built-in as option.

Model	Built-in modules	Filter characteristics	Number of channels
3344	DT-5FL or DT-6FL	Lowpass	8 channels max.

Fixed Frequency Filter
A cutoff (or ceter) frequency and detail specifications are specified by customers.
Various types of semi-custom-made filters are prepared.

Model	Built-in modules	Filter characteristics	Number of channels
DV-04	CF or DV series	Lowpass/Highpass/Bandpass/Bandelimination	4 channels max.
