E-series power sensor specifications E-series CW power sensor specifications The E-series of power sensors have their calibration factors stored in EEPROM and operate over a wide dynamic range. They are designed for use with the EPM series of power meters and two classes of sensors are available: Table 6 Model E4412A Frequency range 10 MHz – 18 GHz E4413A 50 MHz – 26.5 GHz • CW power sensors (E4412A and E4413A). • Average power sensors (E9300 sensors).
The chart in figure 1 shows the typical uncertainty in making a relative power measurement, using the same power meter channel and the same power sensor to obtain the reference and the measured values. Example A illustrates a relative gain (amplifier measurement). Example B illustrates a relative loss (insertion loss measurement). This chart assumes negligible change in frequency and mismatch occur when transitioning from the power level used as the reference to the power level being measured.
E-series E9300 average power sensor specifications The E-series E9300 wide dynamic range, average power sensors are designed for use with the EPM family of power meters. These specifications are valid ONLY after proper calibration of the power meter and apply for CW signals unless otherwise stated.
Typical SWR, 10 MHz to 18 GHz, (25°C ± 10°C) for E9300A and E9301A sensors Typical SWR, 9kHz to 6 GHz, (25°C ± 10°C) for E9304A sensors 12
Typical SWR, 10 MHz to 18 GHz, (25°C ± 10°C) for E9300B and E9301B sensors Typical SWR, 10 MHz to 18 GHz, (25°C ± 10°C) for E9300H and E9301H sensors 13

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 10: the typical maximum additional power linearity error due to temperature change after calibration, for small changes in temperature, is ±0.15%/°C (valid after zeroing the sensor). For large changes in temperature, refer to Table 11.
E-series E9300 average power sensors Switch point data The E9300 power sensors have two paths, a low power path covers: -60 to -10 dBm (“A” suffix sensors), -30 to +20 dBm (“B” suffix sensors), and -50 to 0 dBm (“H” suffix sensors). The high power path covers: 10 to +20 dBm (“A” suffix sensors), +20 to +44 dBm (“B” suffix sensors), and 0 to +30 dBm (“H” suffix sensors). The power meter automatically selects the proper power level path.
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 data sheet with the serial number on the power sensor you are using. The CF corrects for the frequency response of the sensor.
8480 series power sensors (with EPM series power meters) The 8480 series power sensors are designed for use with the 435B, 436A, 437B, 438A, 70100A, E1416A and now the E4418B and E4419B power meters. 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 dBm to +44 dBm). Table 14.
