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.

Agilent EPM Series Power Meters
The standard just got better! What’s new? • Fast measurement speeds (up to 200 readings per second) • Wide dynamic range sensors (-70 dBm to +44 dBm), sensor dependent • Calibration factors stored in EEPROM • Rechargeable battery option Agilent Technologies power meters have long been recognized as the industry standard for RF and microwave power measurements. Now, with our latest generation of power meters and sensors, Agilent provides totally updated and exciting choices.
Designed for manufacturing Fast speed means increased productivity Fast measurement speed is essential in the high volume manufacturing of RF and microwave components and systems. Faster test time improves your productivity—letting you test more devices in less time. E-series sensors along with the E4418B power meter provide a FAST measurement mode that lets you make up to 200 readings per second.
Large LCD display High resolution display with back lighting provides a wide viewing angle for all the displayed data. Preset/local Returns the power meter to local control. If already in local, returns the power meter to the default condition. Arrowkeys Allow positioning of the cursor for editing purposes and for character selection. Softkeys Provide user menu selection. Power ref 1.00 mW, 50 MHz source used for power sensor calibration (traceable to NIST).
Easy to learn ... easy to use Increase your productivity with an easy-to-learn, easy-to-use power meter. The EPM series has been designed with the user in mind. Hardkeys such as ZERO/CAL allow access to the most frequently used power meter functions. Softkeys provide measurement control through user selection. The high resolution LCD display (with backlighting), large characters, and split screens provide easy viewing of information. Rear panel features • DC recorder output, 0 to 1 Volt.
Designed for installation and maintenance Wide dynamic range allows high and low power measurements with a single sensor One E-series CW sensor covers the range -70 to +20 dBm, while the E9300 sensors operate from -60 to +44 dBm (25W), depending on the sensor. This wide dynamic range capability saves you time and money as you can measure both high (transmitter monitor points) and low (receiver) power levels using a single sensor.
The battery option and operating case bring Agilent’s power accuracy and ease-of-use to field applications. Versatile display is suitable for your measurement needs In the installation and maintenance environment, it is important to be able to see the power meter’s display from a distance and in a variety of lighting conditions. The EPM series power meter has been designed to meet this need. Contrast adjustment lets you set the brightness of the display.
Designed for R&D Optimum measurement accuracy and repeatability means confidence in your power measurements The EPM series power meters maintain the high accuracy standard set by the Agilent 437B and 438A— being designed to have excellent linearity. Instrumentation absolute accuracy, due to the meter electronics, is specified to be +0.02 dB in logarithmic mode and +0.5% in linear mode—making this source of error a negligible part of the overall measurement uncertainty.
Designed for R&D More choice means the correct sensor for your application The EPM series power meter’s compatibility with both the 8480 series and E-series sensors provides R&D engineers with more choice: • The EPM series power meter and 8480 series sensor combination form a high precision, average power measurement system operating in the frequency range 100 kHz to 110 GHz (depending on the selected sensor) over a 50 dB maximum dynamic range.
