SPG8000 Specifications and Performance Verification
Be sure you have performed the performance verification preparation before
proceeding. (See page 19, Performance verification preparation.)
Performance verification procedures can be performed individually, if needed.
Check whether Option 3G is installed on your instrument. If Option 3G is
installed, then you should use the setups in the following procedures that are
called out for Option 3G.
1. Press the SYSTEM button to access the SYSTEM menu.
2. Press the up (▲) or down (▼) arrow button to select SYSTEM : OPTIONS.
The second line of the display lists the installed options. The readout will
show 3G if Option 3G is installed.
Check the SDI diagnostics before performing the performance verification tests.
Some of the SDI diagnostics are available only when the instrument is in factory
