Procedure
Step 1. Disconnect the power cable from the E4980A and allow 1 minute for the internal
capacitors to discharge.
NOTE
Dangerous energy/voltage exists when the E4980A is in operation, and for a time after it is
powered down. Allow 1 minutes for the internal capacitors to discharge.
Step 2. Remove the Scanner Interface Board according to the procedure for describing in "Scanner
Interface" Chapter of the User's Guide.
NOTE
The interface board contains electronic components that can be damaged by static
electricity through electrostatic discharge (ESD). To prevent ESD damage, maintain
frequent contact with any bare sheet metal surface on the chassis. A grounding wrist strap
(or similar device) is useful for this purpose. Handle the board carefully at all times. Avoid
touching electronic components or circuit paths.
NOTE
Before performing Step 3, note the switch settings on the scanner interface board in order
to return them to the same settings at the end of this function test.
Step 3. Set S1 and S2 on the scanner interface board to the same settings as when the board is
shipped from the factory referring to Figure 4-12, Table 4-10, and Table 4-11.
