For power levels greater than 0 dBm, add 0.5%/dB to the calibration factor uncertainty specification E-Series CW Power Sensor Specifications (Continued) Calibration factor (CF) and reflection coefficient (Rho) Calibration factor and reflection coefficient data are provided at 1 GHz increments on a data sheet included with the power sensor. This data is unique to each sensor. If you have more than one sensor, match the serial number on the data sheet with the serial number on the power sensor you are using.

E-Series E9300 Average Power Sensor Specifications (Continued) Effects of change in temperature on linearity Note: If the temperature changes after calibration and you choose not to re-calibrate the sensor, the following additional power linearity error should be added to the linearity specs in Table 9. For small changes in temperature: The typical maximum additional power linearity error due to small temperature change after calibration is ± 0.15%/°C (valid after zeroing the sensor).
E-Series E9300 Average Power Sensor Specifications (Continued) Switch point data The E9300 power sensors have two paths as shown in Table 7. The power meter automatically selects the proper power level path. To avoid unnecessary switching when the power level is near the switch point, switching point hysteresis has been added. E9300 “A” suffix sensors example: –– Hysteresis causes the low power path to remain selected until approximately –9.
E-Series E9300 Average Power Sensor Specifications (Continued) Calibration factor (CF) and reflection coefficient (Rho) Calibration factor and reflection coefficient data are provided at frequency intervals on a data sheet included with the power sensor. This data is unique to each sensor. If you have more than one sensor, match the serial number on the certificate of calibration (CoC) with the serial number on the power sensor you are using. The CF corrects for the frequency response of the sensor.

Mechanical characteristic Mechanical characteristics such as center conductor protrusion and pin depth are not performance specifications. They are, however, important supplemental characteristics related to electrical performance. At no time should the pin depth of the connector be protruding.
