Giga-tronics 58542 - Table B-2: Power Sensor Cal Factor Uncertainties

58542 VXIbus Universal Power Meter
B-4 Publication 21555, Rev. E, September 2002
Notes:
1. The K connector is electrically and mechanically compatible with the APC-3.5 and SMA connectors.
2. Power coefficient equals <0.01 dB/Watt.
3. Power coefficient equals <0.015 dB/Watt.
4. For frequencies above 8 GHz, add power linearity to system linearity.
5. Peak operating range above CW maximum range is limited to <10% duty cycle.
6. Includes uncertainty of reference standard and transfer uncertainty. Directly traceable to NIST.
7. Square root of sum of the individual uncertainties squared (RSS).
8. 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.
