1 Introduction
What You’ll Find In This Chapter This Chapter introduces you to the HP E-series E9300 power sensors, some detail on their operation, the minimum power meter requirements and connecting to your power meter. It contains the following sections: • “General Information” on page 13 • “The Agilent E-Series E9300 Power Sensors in Detail” on page 14 • “Getting Started” on page 16 Figure 1 Typical HP E-series E9300 power sensors.
General Information General Information Welcome to the HP E-series E9300 power sensors Operating and Service Guide! This guide contains information about the initial inspection, operation, specifications and repair of the HP E-series E9300 power sensors. Use this guide as a supplement to the Agilent EPM series power meters User’s Guides. It is 3-hole drilled to allow you to retain it in the power meter’s binder.
General Information The Agilent E-Series E9300 Power Sensors in Detail Most power sensors used for measuring average power employ either thermocouple or diode technologies. Diode based sensors frequently rely on the application of correction factors to extend their dynamic range beyond their square law response region, typically -70 dBm to -20 dBm. However, while this technique achieves wide dynamic range capability, it is limited to continuous wave (CW) signals outside the square law region.
General Information average of complex modulation formats across a wide dynamic range, irrespective of signal bandwidth. The dual range Modified Barrier Integrated Diode (MBID)1 package includes further refinements to improve power handling allowing accurate measurement of high level signals with high crest factors without incurring damage2 to the sensor. These sensors measure average RF power on a wide variety of modulated signals and are independent of the modulation bandwidth.
Getting Started Getting Started 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, notify the nearest Agilent Technologies office. Keep the damaged shipping materials (if any) for inspection by the carrier and a Agilent Technologies representative.
Getting Started First check the section labelled '63 5HYLVLRQ . Release A.01.11 or later is required. If your power meter has an earlier release, please contact your nearest Service Office (listed on page -70) to arrange an upgrade. Next check the section labelled 0DLQ ) : 5HY . Release A1.04.00 or later is required for single channel meters; release A2.04.00 or later is required for dual channel meters. For E9300 power sensors with suffix ‘B’ or ‘H’, firmware revision A1.06.
Getting Started • On the power meter, press Zero Cal , Zero (or Zero A / Zero B ). During zeroing the wait symbol is displayed. • When the wait period is complete connect the Agilent E-series power sensor to the power meter’s POWER REF output. • Press Cal (or Cal , Cal A / Cal B ). The wait symbol is again displayed during calibration. On completion the power meter and sensor are ready to connect to the device under test (DUT).
2 Making Measurements
What You’ll Find In This Chapter This Chapter shows you how to use the HP E-series E9300 power sensors to make power measurements on signals with different modulation formats. For all other operations please refer to your Agilent EPM series power meter User’s Guide.
Power Meter Configuration Changes Power Meter Configuration Changes The Agilent EPM series power meter recognizes when an Agilent E-series E9300 power sensor is connected. The sensor calibration data is automatically read by the power meter. In addition, the HP E-series E9300 power sensors change the auto-averaging settings used by the power meter. These are also automatically configured.
Measuring Spread Spectrum and Multitone Signals Measuring Spread Spectrum and Multitone Signals To achieve high data transfer rates within a given bandwidth, many transmission schemes are based around phase and amplitude (I and Q) modulation. These include CDMA, W-CDMA and digital television. These signals are characterized by their appearance on a spectrum analyzer display — a high amplitude noise-like signal of bandwidths up to 20 MHz. An 8 MHz bandwidth digital television signal is shown in Figure 5.
Measuring Spread Spectrum and Multitone Signals CDMA Signal Measurements Figure 6 and Figure 7 show typical results obtained when measuring a CDMA signal. In these examples, the error is determined by measuring the source at the amplitude of interest, with and without CDMA modulation, adding attenuation until the difference between the two values stops changing. The CW sensor in Figure 6 uses correction factors to correct for power levels beyond its square law operating region. 1.
Measuring Spread Spectrum and Multitone Signals Multitone Signal Measurements In addition to wide dynamic range, the HP E-series E9300 power sensors also have an exceptionally flat calibration factor versus frequency response across the entire frequency range as shown in Figure 8. This is ideal for amplifier intermodulation distortion measurements where the components of the two-tone or multitone test signal can be separated by hundreds of MHz.
Measuring TDMA Signals Measuring TDMA Signals Power Meter and Sensor Operation The voltages generated by the diode detectors in the power sensor can be very small. Gain and signal conditioning are required to allow accurate measurement. This is achieved using a 220 Hz (440 Hz in fast mode) square wave output from the power meter to drive a chopper-amplifier in the power sensor.
Measuring TDMA Signals Note You should also ensure the filter is not reset when a step increase or decrease in power is detected by switching the step detection off. Switch off step detection as follows: System Inputs 2. , Input Settings , More . Press the Filter softkey to access the filter menu. 3. Press Step Det Off On to highlight Off . 1.
Electromagnetic Compatibility (EMC) Measurements Electromagnetic Compatibility (EMC) Measurements The low frequency range of the Agilent 9304A make it the ideal choice for making EMC measurements to CISPR (Comite International Special Perturbations Radioelectriques) requirements, and electromagnetic interference (EMI) test applications such as the radiated immunity test (IEC61000-4-3). DC coupling of the Agilent 9304A input allows excellent low frequency coverage.
Measurement Accuracy and Speed Measurement Accuracy and Speed The power meter has no internal ranges. The only ranges you can set are those of the HP E-series E9300 power sensors (and other HP E-series power sensors). With an Agilent E-series E9300 power sensor the range can be set either automatically or manually. Use autoranging when you are not sure of the power level you are about to measure.
Measurement Accuracy and Speed Configure the power meter as follows: Note The example shows the key labels for a single channel power meter. Dual channel meters are similar, adding channel identification to the softkey labels. 1. 2. Press System , Input Settings . The current setting is displayed under Inputs the Range softkey. To change this press Range . A pop up window appears. Use or to highlight your choice. To confirm your choice press Enter .
Measurement Accuracy and Speed power path (-10 dBm to +20 dBm) should be used to ensure a more accurate measurement of this signal. However, range holding in “UPPER” (the high power path), for a more accurate measurement, results in considerably more filtering. Speed and Averaging The same signal also requires that consideration is given to measurement speed. As shown above, in autoranging mode the Agilent EPM series power meter selects the low power path in the Agilent E-series E9300 power sensor.

E9300/1/4/A Power Sensor Specifications Switching Point The Agilent E-series E9300 power sensors have two paths, a low power path covering -60 dBm to -10 dBm, and a high power path covering -10 dBm to +20 dBm. The power meter automatically selects the proper power level path. To avoid unnecessary switching when the power level is near the -10 dBm point, Switching Point Hysteresis has been added. This hysteresis causes the low power path to remain selected until approximately -9.

Service Service Service instructions consist of principles of operation, troubleshooting, and repairs. Principles of Operation The A1 Bulkhead assembly on the Agilent E-series E9300 power sensors provides a 50 ohm load to the RF signal applied to the power sensor. The A1 Bulkhead assembly on the E9300/1B sensors includes a 30 dB attenuator that can be disconnected by means of a Type-N connector. The A1 Bulkhead assembly on the E9300/1H sensors includes a 10 dB attenuator in the front end.
Service Troubleshooting Troubleshooting information is intended to first isolate the power sensor, the cable, or the power meter as the defective component. When the power sensor is isolated, an appropriate Sensor Module must be used for repair. If error message 241 or 310 is indicated on the power meter, suspect a 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.
Service Figure 26 Removing Power Sensor Shell 1. At the rear of the power sensor, insert the blade of a screwdriver between the plastic shells (See Figure 26).
