Power Sensor Electrical Overstress (EOS) Failure Verification Guideline
Applikationsberichte
Introduction
Electrical Overstress (EOS) of a Power Sensor consists of:
- Overpowering
- Overvoltage
- ESD damage
Subjecting a power sensor to EOS is considered a misuse or self-abuse, and is excluded from Keysight Technologies’ standard warranty coverage.
Overpowering
Power sensor converts RF signal to DC signal for power meter to display as a power value in dBm or watts after processing.
The maximum measurable power of a power sensor varies depending on the sensor model. Incidentally, Keysight Technologies’ service centers receive a high number of power sensor that have been damaged due to overpowering of the sensor bulkhead, resulting in the damage of the internal thin film circuit.
