REMOVAL PROCEDURES
WARNING
Hazardous voltages exist on the power supply. To avoid electrical shock,
disconnect the power from the instrument before performing the following
procedures. After disconnecting the power, wait at least three minutes for the
capacitors on the power supply board to discharge before servicing the
instrument.
CAUTION Electrostatic discharge can damage electronic components. Use grounded wrist
straps and mats when performing any service to the logic analyzer.
CAUTION Do not remove or replace any circuit assemblies in this instrument while power
is applied. The assemblies contain components which may be damaged if the
assembly is removed or replaced while the instrument is powered.
Remove the Probe Mounting Plate and the Probe Cables (See Figure 1)
1. Turn off the power and unplug the logic analyzer.
2. Using a #1 pozidrive screwdriver, loosen the five screws and remove the probe mounting plate (MP23).
3. Remove the probe cables (W1) by pulling them out of their connectors on the rear panel.
Remove the Cover Assembly (See Figure 1)
1. Using a T10 TORX screwdriver, remove the seven screws holding the trim strip (MP6) and the cover
assembly (MP22) to the chassis assembly (MP29). Remove the trim strip (MP6).
2. Using a T10 TORX screwdriver, remove the four screws to remove the four rear feet (MP7).
3. Using a T10 TORX screwdriver, remove the two screws that attach the handle assembly (MP34) to the
chassis assembly (MP29). Remove the handle assembly (MP34).
4. To remove the cover assembly (MP22) , set the instrument’s front panel facing toward you. Prepare to
remove the cover by using a T10 TORX to turn back three revolutions each the four screws fastening the
equipment pouch to the cover assembly. Slide the chassis toward the front, out of the cover. Set the
instrument on a static-safe work area.
Remove the Disk Drive (See Figures 1)
1. Disconnect the flexible disk drive cable (W5) from the CPU board (A2). Disconnect the hard disk drive cable
(W4) from the CPU board (A2).
2 . Using a T10 TORX screwdriver, remove the two screws holding the disk drive bracket (MP3) to the support
tray (MP24).
3 . Slide the disk drive bracket assembly toward the rear of the instrument, then lift it up and out.
5
Remove the Acquisition Board (See Figures 1 and 2)
1. Remove the PCB locking pins (MP1) from the chassis assembly (MP29). Slide the support tray (MP24) out
of the chassis assembly.
2. On the bottom of the acquisition board (A4), disconnect the following cables:
• Power Sense
• Fan
• Power Supply
• CPU Board
3. On the top of the acquisition board, disconnect the following cables:
• Trigger input (white wire to J6)
• Trigger output (orange wire to J5)
