The Tektronix 80A02 is a single-channel EOS/ESD Protection Module designed to safeguard the sensitive input circuitry of Tektronix 80E00-series sampling modules from electrostatic discharge (ESD) and electrical overstress (EOS). It operates by automatically grounding the input until a control signal safely routes the signal path.
