CONTROLS, CONNECTORS,
AND INDICATORS
The following descriptions are intended to familiarize
the operator with the location and function of the instru
ment's controls, connectors, and indicators.
POWER AND DISPLAY
Refer to Figure 3-1 for location of items 1 through 9.
0 INTENSITY Control—Adjusts brightness of the crt
trace display. This control does not affect intensity of
the crt readout display.
^ 7 ) BEAM FIND Switch—When held in, compresses the
display to within the graticule area. Aids the operator
in locating off-screen displays.
( T ) SCALE ILLUM Control-Adjusts the light level of
the graticule illumination.
( T ) POWER Switch-Turns instrument power on and off.
Press in for ON; press again for OFF. An internal
indicator in the switch shows green when the switch
is on and black when it is off. Front-panel settings
that were unchanged for at least 10 seconds prior to
power-off will be returned when power is reapplied to
the instrument.
(V ) CRT—Has an 80-mm vertical and 100-mm horizontal
display area. Internal graticule lines eliminate parallax
viewing error between the trace and the graticule
lines. Rise-time measurement points are indicated
at the left edge of the graticule.
@ FOCUS Control—Adjusts the display for optimum
definition.
(jP) TRACE ROTATION Control—Operator-adjusted
screwdriver control used to align the crt trace with
the horizontal graticule lines. Once adjusted, it does
not require readjustment during normal operation of
the instrument.
READOUT INTENSITY Control-Adjusts the inten
sity of the crt readout display. This control is also
used to either enable or disable the scale-factor
display. Setting the control to MIN reduces the
readout intensity to minimum. Clockwise rotation
from midrange increases the readout intensity and
enables the scale-factor display; counterclockwise
rotation from midrange also increases the intensity
but disables the scale-factor display. Delta Volts and
Delta Time readouts and control messages will
continue to be enabled even when the scale-factor
display is disabled.
ASTIG Control—Operator-adjusted screwdriver con
trol used in conjunction with the FOCUS control to
obtain a well-defined display over the entire graticule
area. Once adjusted, it does not require readjustment
during normal operation of the instrument.
