Copy the EEPROM Disk The Agilent 8702D is shipped from the factory with an EEPROM backup disk which is unique to each instrument. The backup disk contains a copy of correction constants which were stored in the instrument’s internal memory at the factory. If your Agilent 8702D should ever be damaged, these correction constants may need to be reinstalled from the disk. Use the following procedure to create a backup copy of the disk. 1 Insert a 3.5-inch disk into the Agilent 8702D’s disk drive. 2 Press PRESET so that the preset state is stored. 3 If the disk is not formatted, press SAVE/RECALL, FILE UTILITIES, FORMAT DISK. • To format a LIF disk, select FORMAT:LIF (The supplied EEPROM backup disk is LIF. The Agilent 8702D does not support LIF-HFS format.) • To format a DOS disk, select FORMAT:DOS. Press FORMAT INT DISK, and answer YES at the query. 4 Press SYSTEM, SERVICE MENU, SERVICE MODES, MORE, STORE EEPR ON, SAVE/RECALL, SAVE RCL MENU, SELECT DISK, INTERNAL DISK, RETURN, SAVE STATE to store the correction-constants data onto floppy disk. A default file “FILE0” is created. The file name appears in the upper left-hand corner of the display. The file type “ISTATE(E)” describes the file as an instrument-state with EEPROM backup. 5 Press FILE UTILITIES, RENAME FILE, ERASE TITLE. Use the RPG and the SELECT LETTER softkey to rename the file “FILE0” to “N12345” where 12345 represents the last 5 digits of the instrument’s serial number. (The first character in the file name must be a letter.) When finished, press DONE. 6 Label the disk with the serial number of the instrument and the words “EEPROM Backup Disk”. Whenever the Agilent 8702D is returned to Agilent Technologies for servicing and/or calibration, the EEPROM backup disk should be returned with the Agilent 8702D. This will significantly reduce the instrument repair time. The EEPROM backup disk procedure is now complete. 1-26 2 Step 1. Initialization 2-3 Step 2. Measurement Calibration Step 3.

If you are using an Agilent 8702D Option 011, perform the tests in Chapter 6, “Performance Tests – Option 011”. Before starting these procedures, allow the instrument to warm up for one hour. Each procedure has a “Performance Test Record” that is located at the end of this chapter. To obtain the same quality of performance testing that Agilent Technologies has administered at the factory, you must perform: • the system verification procedures in Chapter 2, “Automated Verification” or Chapter 3, “Manual Verification”. • all of the performance test procedures in this chapter. This quality of performance testing guarantees that the analyzer is performing within all of the published specifications. Agilent Technologies will issue a Certificate of Calibration for your analyzer if two conditions are met. 1 Your analyzer passes all the performed tests. 2 The equipment and standards that you used to perform the tests are traceable to a national standards institute. NOTE If you have a particular type of measurement application that does not use all of the analyzer’s measurement capabilities, you may ask your nearest Agilent Technologies Service Office for a subset of specifications that you want verified. However, this does create a potential for making incorrect measurements, by using a different application than what was specified. 4-2 Performance Tests 1.

If you are not using an Agilent 8702D Option 011, refer to Chapter 4, “Performance Tests”. Before starting these procedures, allow the instrument to warm up for one hour. Each procedure has a “Performance Test Record” that is located at the end of this chapter. To obtain the same quality of performance testing that Agilent Technologies has administered at the factory, you must perform: • the system verification procedures in Chapter 5, “Automated Verification – Option 011”. • all of the performance test procedures in this chapter. This quality of performance testing guarantees that the analyzer is performing within all of the published specifications. Agilent Technologies will issue a Certificate of Calibration for your analyzer if two conditions are met. 1 Your analyzer passes all the performed tests. 2 The equipment and standards that you used to perform the tests are traceable to a national standards institute. NOTE If you have a particular type of measurement application that does not use all of the analyzer’s measurement capabilities, you may ask your nearest Agilent Technologies Service Office for a subset of specifications that you want verified. However, this does create a potential for making incorrect measurements, by using a different application than what was specified. 6-2 Performance Tests – Option 011 1. Source Frequency Range and Accuracy WARNING Any servicing, adjustment, maintenance, or repair of this product must be performed only by qualified personnel. Repair information provided in the In Case of Difficulty sections of this chapter are provided for qualified service personnel and are intended to be used with the Agilent 8753D Service Guide. Agilent 8753D is shown in the figures The procedures in this chapter are designed to work with Agilent 8702D and Agilent 8753D instruments. Because of this, many of the figures label the instrument being tested as an Agilent 8753D. Simply substitute your Agilent 8702D for the Agilent 8753D. 1.

Contact the nearest Agilent Technologies office for service, if necessary. A list of Agilent Technologies service offices is provided on page 7-8. If the display does not light ❒ Check that the power cord is fully seated in both the main power receptacle and the Agilent 8702D’s power module. ❒ Check that the AC line voltage selector switch is in the appropriate position (230V/115V) for your available power supply. ❒ Check that the Agilent 8702D’s AC line fuse is not open. Refer to Figure 7-1 to remove the fuse from the power module. Use an ohmmeter to check the fuse. The 3A, 250V fuse is Agilent Technologies part number 2110-0780. 7-2 If You Encounter a Problem If the fan does not run WARNING The power cord is connected to internal capacitors that may remain live for 10 seconds after you disconnect the cord from the power supply. Figure 7-1. Line Fuse Removal and Replacement WARNING For continued protection against fire hazard, replace the fuse with the same type and rating. If the fan does not run 1 Switch the LINE power switch to the off position. 2 Check that the fan blades are not jammed or obstructed. If data entry keys don’t respond ❒ Check that the “entry off” function is not enabled. 7-3 If You Encounter a Problem If there is no RF signal The “entry off” is enabled after you press the ENTRY OFF key. To return to normal entry mode, press any function key that has a numeric parameter associated with it. For example, START. ❒ Check that none of the keys are mechanically stuck. ❒ Check that the selected key is designed to accept data. For example, SCALE REF accepts data, but SYSTEM does not. ❒ Ensure that you are not attempting to enter a value that is greater than or less than its limit. ❒ Check that the front panel “R” HP-IB STATUS light is not illuminated. If the “R” HP-IB STATUS light is illuminated, a test sequence may be running, or a connected computer controller may be sending commands or instructions to, or receiving data from, the instrument. Press LOCAL if you want to return to local control. If there is no RF signal ❒ Check that the signal at the test ports is switched on. a Press MENU, POWER, SOURCE PWR until ON appears on the SOURCE PWR softkey label. b Press MENU, POWER, POWER TRIP on OFF until OFF appears on the POWER TRIP softkey label. ❒ If you are applying external modulation (AM) to the Agilent 8702D, check the external modulating signal or external gate/trigger signals for problems. CAUTION If the error message: CAUTION: OVERLOAD ON INPUT X, POWER REDUCED appears on the display, too much source power is being applied at the input. In such a case, the input power will need to be reduced before the source power will remain on. ❒ Look for phase-lock error messages and then contact your nearest Agilent Technologies office for service.

Include copies of additional failure information (such as the instrument failure settings, data related to instrument failure, and error messages) along with the instrument being returned. Preparing the instrument for shipping 1 Write a complete description of the failure and attach it to the instrument. Include any specific performance details related to the problem. The following 7-5 If You Encounter a Problem Returning the Instrument for Service information should be returned with the instrument. • Type of service required. • Date instrument was returned for repair. • Description of the problem: • Whether problem is constant or intermittent. • Whether instrument is temperature-sensitive. • Whether instrument is vibration-sensitive. • Instrument settings required to reproduce the problem. • Performance data. • Company name and return address. • Name and phone number of technical contact person. • Model number of returned instrument. • Full serial number of returned instrument. • List of any accessories returned with instrument. 2 Cover all front or rear-panel connectors that were originally covered when you first received the instrument. CAUTION Cover electrical connectors to protect sensitive components from electrostatic damage. Cover optical connectors to protect them from damage due to physical contact or dust. CAUTION Instrument damage can result from using packaging materials other than the original materials. Never use styrene pellets as packaging material. They do not adequately cushion the instrument or prevent it from shifting in the carton. They may also cause instrument damage by generating static electricity. 3 Pack the instrument in the original shipping containers. Original materials are available through any Agilent Technologies office. Or, use the following guidelines: • Wrap the instrument in antistatic plastic to reduce the possibility of damage caused by electrostatic discharge. • For instruments weighing less than 54 kg (120 lb), use a double-walled, corrugated cardboard carton of 159 kg (350 lb) test strength. • The carton must be large enough to allow approximately 7 cm (3 inches) on all sides of the instrument for packing material, and strong enough to accommodate the weight of the instrument. • Surround the equipment with approximately 7 cm (3 inches) of packing material, to protect the instrument and prevent it from moving in the carton. If packing foam is not available, the best alternative is S.D-240 Air Cap™ from 7-6 If You Encounter a Problem Returning the Instrument for Service Sealed Air Corporation (Commerce, California 90001). Air Cap looks like a plastic sheet filled with air bubbles. Use the pink (antistatic) Air Cap™ to reduce static electricity. Wrapping the instrument several times in this material will protect the instrument and prevent it from moving in the carton. 4 Seal the carton with strong nylon adhesive tape. 5 Mark the carton “FRAGILE, HANDLE WITH CARE”. 6 Retain copies of all shipping papers. 7-7 If You Encounter a Problem Agilent Technologies Service Offices Agilent Technologies Service Offices Before returning an instrument for service, call the Agilent Technologies Instrument Support Center at (800) 403-0801, visit the Test and Measurement Web Sites by Country page at http://www.tm.agilent.com/tmo/country/English/ index.html, or call one of the numbers listed below.
