Introduction 1 General Information Warranty The power sensors are warranted and certified as indicated on the inside cover of this manual. Instruments Covered by Manual These instruments have a two- part serial number: the prefix (two letters and the first four numbers), and the suffix (the last four numbers). The two letters identify the country in which the unit was manufactured.
1 Introduction These power sensors measure CW power, displayed on a compatible power meter in logarithmic (dBm or dB) or linear (Watts or %) measurement units. The E4413A is shipped with a 3.5- mm to Type- N adapter, part number 08485- 60005. N O TE N O TE The E4412A and E4413A power sensors are compatible ONLY with the newer E44XX-Series power meters.

In a relative measurement, two power levels are compared using a single sensor.
1 Introduction EXAMPLE A (Amplifier Gain Measurement): Input power (reference) = –35 dBm; power measured = +6 dBm’ so the relative gain is +41 dB. the chart indicates a typical error of ±6 %, which corresponds to +0.25 dB/–0.27 dB uncertainty in the gain measurement. EXAMPLE B (Insertion Loss Measurement): Reference power = –25 dBm; power measured = –35 dBm, for the case of an insertion loss of 10 dB. the chart indicates a typical error of ±1 %, which corresponds to ±0.

Introduction 1 Installation Initial Inspection Inspect the shipping container for damage. If the shipping container or packaging material is damaged, it should be kept until the contents of the shipment have been checked mechanically and electrically. If there is mechanical damage or if the instrument does not pass the performance tests, notify the nearest Agilent Technologies office. Keep the damaged shipping materials (if any) for inspection by the carrier and a Agilent Technologies representative.
1 Introduction Storage and Shipment Environment The instruments should be stored in a clean, dry environment. The following limitations apply to both storage and shipment: Temperature –55 to +75 ºC Relative Humidity <95 % at 40 ºC Altitude <15,240 metres (50,000 feet) Original Packaging Containers and materials identical to those used in factory packaging are available through Agilent Technologies offices.
Introduction 1 Operation Precautions WARN IN G BEFORE CONNECTING THE POWER SENSOR TO OTHER INSTRUMENTS, ensure that all instruments are connected to the protective (earth) ground. Any interruption of the protective earth grounding will cause a potential shock hazard that could result in personal injury and cause damage to the power sensor. If the following energy and power levels are exceeded, the power meter system may be damaged.
1 Introduction Power Meter Calibrations Follow the calibration procedures given in your power meter manual. The E4413A power sensor is fitted with 3.5 mm (m) connectors as standard. To convert the 3.5 mm (m) connector for calibration, an adapter (3.5 mm (f) to Type- N (m)) is included with the power sensor. See Figure 3. Figure 3 N O TE E4413A power sensor with adapter The 3.5 mm to Type-N adapter is intended for the use of 1 mW, 50 MHz power reference of the power meter only.
Introduction 1 Performance Test Standing Wave Ratio (SWR) and Reflection Coefficient (Rho)Performance Test This section does not establish preset SWR test procedures since there are several test methods and different equipm ent available for testing the SWR or reflection coefficient. Therefore, the actual accuracy of the test equipment must be accounted for when measuring against instrument specifications to determine a pass or fail condition.

1 Introduction Service Service instructions consist of principles of operation, troubleshooting, and repairs. Principles of Operation The A1 Bulkhead assembly provides a 50 ohm load to the RF signal applied to the power sensor. A diode assembly in the bulkhead rectifies the applied RF to produce a dc voltage which varies with the RF power across the 50 ohm load. Thus the voltage varies with the RF power dissipated in the load. With maximum specified RF power (100 mW) the dc voltage is approximately 1V.
Introduction 1 If error message 241 or 310 is indicated on the power meter, suspect failed power sensor. If no error message is displayed, but a problem occurs when making a measurement, try replacing the cable from the power meter to the power sensor. If the problem still exists, try using a different power sensor to determine if the problem is in the power meter or in the power sensor. CAU T ION Electrostatic discharge will render the power sensor inoperative.
1 Introduction Clean the connector face using a cotton swab dipped in isopropyl alcohol. If the swab is too big use a round wooden toothpick wrapped in a lint free cotton cloth dipped in isopropyl alcohol. Refer to Agilent Application Note 326, Principals of Microwave Connector Care (5954- 1566) or Microwave Connector Care (08510- 90064) for proper cleaning methods. Disassembly Procedure Figure 5 CAU T ION Removing Power Sensor Shell Diassemble the power sensor only in a static free workstation.
Introduction 1 Reassembly Procedure 1 Replace the magnetic shields and the plastic shells as shown in Figure 5. Snap the plastic shells together.
