Assembly Replacement
Procedure 13. Rear Frame/Rear Dress Panel
Procedure 13. Rear Frame/Rear Dress Panel
Removal
WARNING The A6 power supply (in E-series and EC-series instruments)
and the A6A1 high voltage (in E-series instruments) assemblies
contain lethal voltages with lethal currents in all areas. Use
extreme care when servicing these assemblies. Always
disconnect the power cord from the instrument before
beginning this replacement procedure. Failure to follow this
precaution can present a shock hazard which may result in
personal injury.
NOTE Diagrams that illustrate features common to E-series and EC-series
instruments are shown with E-series instruments. Where features
differ for E-series and EC-series instruments, separate diagrams are
provided.
1. Disconnect the line-power cord from the spectrum analyzer.
2. Remove the spectrum analyzer cover, and place the spectrum
analyzer on its right side frame.
3. Fold out the A2, A3, A4, and A5 assemblies as described in
"Procedure 5. A2, A3, A4, and A5 Assemblies Removal," steps 3
through 5.
4. Disconnect the HP-IB cable at A2J5.
5. Place the spectrum analyzer top-side-up on the work bench with A2
through A5 folded out to the right.
For EC-series instruments, proceed to step 13. For E-series
instruments proceed to step 6.
WARNING The voltage potential at A6A1W3 is +9 kV. Disconnect at the
CRT with caution! Failure to properly discharge A6A1W3 may
result in severe electrical shock to personnel and damage to the
instrument.
6. Connect the spectrum analyzer line-power cord to provide proper
grounding while discharging the A6A1W3 post-accelerator cable.
Make sure that the spectrum analyzer line-power switch is in the off
position.
