Press Release Summary:
Model 601 contains tunable 8-pole Butterworth highpass filter followed by tunable 8-pole Butterworth lowpass filter. Both filter responses are flat in pass band (unity gain) and roll off at 96 dB per octave beyond corner frequency. Corner frequencies can be set from 100 Hz to 40 kHz at front panel or over serial link from PC. Unit includes input analog anti-aliasing lowpass filter, variable gain output amplifier, and analog lowpass output filter.
Original Press Release:
Model 601 Tunable Highpass/Lowpass Filter
TDL® Technology, Inc. announces their Model 601 Tunable Highpass/Lowpass Filter. The instrument contains a tunable 8-pole Butterworth highpass filter followed by a tunable 8-pole
Butterworth lowpass filter to easily implement highpass, lowpass and bandpass filters. Both filter responses are flat in the pass band (unity gain) and roll off at 96 dB per octave beyond the corner frequency. Corner frequencies can be set from 100 Hz to 40 kHz at the front panel or over a serial link from a PC computer. The unit is controlled by a Microchip PIC microprocessor and includes an input analog anti-aliasing lowpass filter, a variable gain output amplifier and an analog lowpass output filter. The microprocessor is in sleep mode when not programming the filters so its clock does not add any output noise.
Single quantity price is $587. USD plus shipping. Availability is stock to four weeks. A full data sheet and User Guide in PDF format can be downloaded from our web site at zianet.com/tdl.
