Maintenance— 2230 Service
3. Disconnect connector P6421 from the Sweep Inter
face board (A13).
4. Disconnect connector P9010 from the middle right
edge of the Main board (A1).
5. Latch Storage circuit board in the servicing position
(see "Storage Circuit Board in the Servicing Position" in
the "Removal and Replacement Instructions" part of this
section.
6. Ground the two signal leads (pins 2 and 3) of four-
wire connectors P2111 and P2112 (see preceding
"Storage Board Latch” part of this section).
7. Disconnect connector P9410 from the Sweep Refer
ence board (A 16).
8. Connect together pins 2 and 4 of J9410.
9. Disconnect connector P4220 from the middle right
side of the Alternate Sweep board (A5).
10. Disconnect connector P4210 from the middle right
half of the Main board (A1).
11. Disconnect connector P9050 from the middle of the
Main board (A1).
12. Disconnect connector P9060 from the middle of the
Main board (A1).
13. Disconnect connector P9320 from the front of the
Main board (A1).
14. Disconnect connector P9301 (P8100 if the instru
ment contains Option 10 or Option 12) from the middle left
corner of the X/Y Plotter board.
Kernel Isolation
The Kernel (Microprocessor, Clock, and Address Latch)
may be isolated from the rest of the circuitry. The Kernel
can then be troubleshot. When the Kernel is functional, the
power-up diagnostics may be used to further troubleshoot
the digital circuitry. Isolate the Kernel by:
1. Removing P9105A.
2. Moving P9105B to its TEST position.
3. Moving P9105C to its TEST position.
4. Moving P9105D to its TEST position.
Figure 6-3 shows the isolated Kernel timing diagrams.
After the Kernel is repaired, restore normal operation by
using the reverse of the preceding procedure.
Switch Interface Voltages
Voltages generated by the interface to front-panel
switches may be used to troubleshoot the instrument. Tim
ing switch interface voltages are shown in Table 6-4.
VERTICAL VOLTS/DIV switch interface voltages are
shown in Table 6-5. Interface voltages for the AC GND DC
switches are shown in Table 6-6.
