HP 16515A/16A - Service 6-7. MODULE REPLACEMENT The effects of ELECTROSTATIC DISCHARGE can damage electronic components. Use grounded wriststraps and mats when performing any kind of service to this module. Installation Considerations: • A two card module must remain screwed together and installed in two adjacent slots. • A one card module may be installed in any available slot • If previously installed modules prevent proper installation, they must be repositioned in the card cage.
HP 16515N16A - Service All multi-card modules will be cabled or screwed together. Care should be taken to pull these cards out together. Refer to the appropriate service manual for any specific precautions during installation. TOP CARD <: NEXT LOWEST 12 18S30/EXI3 Figure 6-13. Endplate Overhang 4. Pull the faulty timing module completely out. 5. If this is a two card module, lay cards on antistatic mat, disconnect intercard cable and using a No. 10 torx ®, remove screws. See figure 6-14. 6.
HP 16515A/16A - Service 7. To reinstall module, lay probe assemblies flat and pointing out to the rear of card. See figure 6-15. Figure 6-15. Cable Position 8. Slide module half way into mainframe card slot(s). 9. Firmly seat bottom card into backplane connector. Keep applying pressure to the center of card end plate while tightening thumb screws finger tight. Note Two card 1 GHz Timing Modules are screwed together.
HP 16515A/16A - Service 6-8. PROBE ASSEMBLY REPLACEMENT The effects of ELECTROSTATIC DISCHARGE can damage electronic components. Use grounded wriststraps and mats when performing any kind of service to this instrument or the cards in it. Installation Considerations: • New probe assemblies must be completely discharged during installation. • Two card modules must be separated before probe assemblies can be changed on the HP 16515A master. Procedure: 1.
HP 16S1SA/16A - Service 3. Starting from the top, begin pulling all filler panel(s) and card(s) out half way. See figure 6-19. All multi-card modules will be cabled or screwed together. Care should be taken to pull these cards out together. Refer to the appropriate seNice manual for any specific precautions during installation. ¢J1 <: NEXT LOWEST 12 165301EX13 Figure 6-19. Endplate Overhang 4. Pull timing module to be serviced completely out. 5.
HP 16515N16A - Service 6. If this is a two card module, and the bad probe assembly is on the HP 16515A Master, disconnect intercard cable and using a No.1 0 torx ® driver, remove the six (6) screws holding cards together. See figure 6-21. Figure 6-21.
HP 16515A/16A - Service 7. Using a No. 10 torx ® driver, remove four screws that hold probe assembly retainer onto card. See figure 6-22. Figure 6-22. Cable And Retainer Removal 8. Remove probe assembly(s) from card connector(s) by lifting up on strain relief tab, then pulling them straight back. The long lengths of coaxial cabling in the probe assemblies can build up an electrostatic potential that can damage the probe circuitry on the card.
HP 16515N16A - Service 6-9. EXTENDER BOARD INSTALLATION The effects of ELECTROSTATIC DISCHARGE can damage electronic components. Use grounded wriststraps and mats when performing any kind of service to this instrument or the cards in it. Installation Considerations: • Any empty slot may be used in the card slot. • When the HP 16516A Expansion Card is placed on the extender board, the HP 16515A Master must be installed directly below extender board.
HP 1651SA/16A - Service 3. Starting from the top, begin pulling filler panel(s) and card(s) out half way. See figure 6-24. Note All multi-card modules will be cabled or screwed together. Care should be taken to pull these cards out together. Refer to the appropriate service manual for any specific precautions. TOP CARD ~1 NEXT LOWEST < 12 18S30/£XI3 Figure 6-24. Endplate Overhang 4.

HP 16515N16A - Service 6. If this is a two card module disconnect intercard cable and using a No.1 0 torx ®, remove the six (6) screws holding cards together. See figure 6-26. Figure 6-26. Screw Removal 7. Slide extender board completely into card cage slot making sure it is firmly seated into the backplane connector. If the HP 16516A Expansion Card is placed on the extender board, the HP 16515A Master must be placed in the card slot directly below the extender board. 8.
