Page 54: Service
Service Service Service instructions consist of principles of operation, troubleshooting, and repairs. Principles of operation The power sensor ‘bulkhead’ assembly converts input RF to a low frequency voltage signal representing the RF power envelope. The input is AC coupled to a 3 dB attenuator followed by a 50 ohm load resistor. -
Page 55: Figure 3-7 Simplified Sensor Block Diagram
Service Figure 3-7 Simplified sensor block diagram The output of the load filter is connected to a gain selectable amplifier with a bandwidth corresponding to the sensor model/ bandwidth spec. The differential configuration minimizes sensitivity to ground noise, DC offset and drift. In normal mode, the amplifier provides maximum bandwidths of 300 kHz, 1.5 MHz, or 5 MHz, allowing the user to match the test signal’s modulation bandwidth to the sophisticated instrument data processing. -
Page 56: Troubleshooting
Service Troubleshooting Troubleshooting information is intended to first isolate the power sensor, cable, or power meter as the defective component. When the power sensor is isolated, an appropriate sensor module must be used for repair. See Table 3-3. If error message 241 or 310 is displayed on the power meter, suspect a power sensor failure. -
Page 57: Disassembly Procedure
Service Disassembly procedure Disassemble the power sensor by performing the following steps: 1 Disassemble the power sensor only in a static free workstation. Electrostatic discharge renders the power sensor inoperative. Figure 3-8 Removing the power sensor shell 2 At the rear of the power sensor, insert the blade of a screwdriver between the plastic shells (See Figure 3-8). -
Page 58: Adjustments
Service Adjustments Adjustments are usually required on a yearly basis. They are normally performed only after a performance verification has indicated that some parameters are out of specification. Performance verification must be completed after any repairs that may have altered the characteristics of the E-Series E9320 power sensors. The E-Series E9320 power sensors can be adjusted using the Keysight N7800 Series calibration software or can be returned to Keysight for adjustments. - Page 59 This information is subject to change without notice.
