Giga-tronics 8003 - Table A-2: Power Sensor Cal Uncertainties

Power Sensors
Manual 20791, Rev. C, June 2001 A-3
See NOTES below
NOTES:
1. The K connector is electrically and mechanically compatible with the APC-3.5 and SMA connectors. Use a Type N(m) to
SMA(f) adapter (P/N 29835) for calibration of power sensors with Type K(m) connectors.
2. For frequencies above 8 GHz, add power linearity to system linearity.
3. Square root of sum of the individual uncertainties squared (RSS).
4. Cal Factor numbers allow for 3% repeatability when connecting attenuator to sensor, and 3% for attenuator measurement
uncertainty and mismatch of sensor/pad combination.
