848xD Series Diode and 8483A Thermocouple Power Sensor Specifications
Calibration factor uncertainties
These thermocouple and diode power sensors provide extraordinary accuracy, stability, and SWR over a wide range of frequencies (100
kHz to 110 GHz) and power levels (–70 to +20 dBm)�
The 8480 Series sensors in the table do not include discontinued models�
Table 13. Typical root sum of squares (rss) uncertainty on the calibration factor data printed on the power sensor.
