Up for sale is a partially working Ithaco 4212 DC-100kHz active filter from university surplus. The filter will pass and appropriately condition signals (with minor DC offset) when the high-pass filter is disabled. When the high-pass is enabled it will clip the waveform at high levels and not pass small signals. The low-pass filter appears good. No attempts at repair have been made. Please be aware that the unit is being sold "AS IS," with NO RETURNS. Remember, pictures are part of the description: if it’s not shown it’s not included. I ship FAST, usually same day or next day morning. (Depends on listing closing time and receipt of payment.)

Seller Notes Partially working. Will pass and appropriately filter signals (with minor DC offset) when the high-pass filter is disabled. When the high-pass is enabled it will clip the waveform at high levels and not pass small signals. Low-pass filter appears good.
