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.
