5- 4 SDA 601 Serial Digital Analyzer
The EPL is arranged in assembly-by-assembly order, as designated in ANSI
Standard Y32.16-1975. Each component is assigned a circuit number according
to its location within a circuit, which is shown in the parts list by combining the
assembly number and the circuit number.
EXAMPLE: R123 on assembly A2 would be listed in the EPL as A2R123.
Assembly listings in the EPL are followed by circuit board-mounted parts in
alphanumeric order. Chassis-mounted parts are listed at the end of the EPL.
NOTE
. The complete part number shown in the parts list should be used when
ordering replacement parts.
Several self-diagnostic tools are built in to the instrument software. Most of
these tools may be found in the Utility/Diagnostics submenu.
The Diagnositics submenu is the last item in the Utility menu. Enter the Utility
menu when the instrument is in a normal operating mode—that is, not in a
menu—by holding
Lock Out
down while pressing
ON
. Once in the Utility menu,
select the Diagnostics submenu by pressing the Y key once; then
ENTER
to access
the Diagnostics choices, which are listed below. Some of the Diagnostic
submenu items are explained in other parts of this manual, or in the SDA601
User manual; the remaining submenu items are discussed after this listing.
