Power Sensors
Publication 21555, Rev. E, September 2002 B-7
Notes:
1. Includes uncertainty of reference standard and transfer uncertainty. Directly traceable to NIST.
2. Square root of sum of the individual uncertainties squared (RSS).
3. Cal Factor numbers allow for 3% repeatability when connecting attenuator to sensor, and 3% for attenuator measurement
uncertainty and mismatch of sensor/pad combination. Attenuator frequency response is added to the Sensor Cal Factors
which are stored in the sensor’s EEPROM.
For additional specifications, see the Series 80350A (P/N 21568) publication and data sheet.
