CAL_PU. Depressing one of the Menu Select/DISPLAY
ON/OFF controls during power-up runs four calibration
routines, BOX, OUT_PORTS, CAL_CLK_DLY, and the
Storage Acquisition Offset. Each routine is run until one of
the menu buttons is again pushed. The BOX and OUT-
PORTS routines are run at the same time. Each routine is
used to
adjust
the
instrument
(see
‘ Adjustment
Procedure') except for OUT_PORTS. OUT_PORTS is
used to check instrument circuitry (see OUT_PORTS).
Exercisers
Instrument exercisers are used to aid in the repair of
the instrument.
CONFIGURATION. This exerciser lists the ROM part
numbers used in the instrument and the options installed
in the instrument.
BOX. This exerciser displays a box (rectangle) on the
crt. Two places in the Menu generate the Box. Gains and
offsets of the storage display system integrators are set
using the Box display (see the "Adjustment Procedure*).
The Display Controller (U9208) is synchronously stimulated
(at a multiple cf NMI) to display the box not using Mis.
CIRCLE. A high resolution circle is displayed on the crt
by this exerciser. This is the only diagnostic that uses all
10 bits of the display DACs (U9210 and U9220).
FP_VALUES. Raw internal front-panel data is displayed
on the crt by this exerciser. Table 6-16 shows the display
format, and Table 6-17 shows the bit definitions for the
display.
NOTE
Digital data is intensified when a control is changed.
All other data is intensified if the data has changed
more than 5 counts since the last display update.
