5.9. SETUP DIAG: DIAGNOSTICS FUNCTIONS
A series of diagnostic tools is grouped together under the SETUPMOREDIAG
menu, as these parameters are dependent on firmware revision (see Appendix A). These
tools can be used in a variety of troubleshooting and diagnostic procedures and are
referred to in many places of the maintenance and trouble-shooting sections of this
manual.

CONFIGURATION
This submenu allows the user to configure the
analyzer’s analog output channels, including
choosing what parameter will be output on each
channel. Instructions that appear here allow
adjustment and calibration of the voltage signals
associated with each output as well as calibration of
the analog to digital converter circuitry on the
motherboard.

the measure and reference outputs of the
SYNC/DEMOD board to verify the signal handling
and conditioning of these signals.
