OPERATING INSTRUCTIONS
AMBIENT TEMPERATURE
CONSIDERATIONS
This instrument can be operated where the ambient
air temperature is between O° and +50° C (+32° and
+122° F}, and can be stored in ambient temperatures
between -40° and +70° C (-40° and +158° F). After
being stored in temperatures beyond the above
operating limits, allow the chassis temperature to
return to within the operating limits before applying
power. Allowing the Monitor to operate at an ambient
temperature substantially higher than that specified
may result in poor reliability as well as inaccurate
performance.
When the 608 is mounted in a rack with other
equipment, it is important that the ambient
temperature surrounding the Monitor does not exceed
+50° C (+122° F). Additional clearance or forced
ventilation methods (fan) may be needed to maintain
ambient temperatures below +50° C (+122° F).
Reliability and performance of the 608 will be affected
if the ventilation holes in the protective panels are
obstructed, or if the 608 is operated at an ambient
temperature higher than +50° C (+122° F). Other
environments and mounting configurations may
require additional cooling measures.
CONTROLS AND CONNECTORS
Controls and connectors necessary for operation of the
608 Monitor are located on the front and rear panels
of the instrument. To make full use of the capabilities
of this instrument, the operator should be familiar
with the function and use of each external control and
connector. The front-panel controls are shown and
described in Figure 2-1. Brief descriptions of the rear-
panel controls and connectors are given in Figure 2-2.
NOTE
Information on controls and connectors for
the available options is located in the
Instrument Options section of this manual.
DETAILED OPERATING
INFORMATION
INPUT SIGNAL REQUIREMENTS
The horizontal (X) and vertical (Y) deflection factors are
set at the factory to one volt for eight divisions of
deflection on each axis. Thus, as shipped, the input
signal required for each division of deflection is 0.125
volt.
@
The Functional Check procedure may be
used to determine if the horizontal and
vertical deflection factors of your particular
instrument meet those set at the factory,
as stated above.
The best transient response from the 608 Monitor is
achieved when the input signal amplitude to the
vertical or horizontal INPUT is no greater than that
sufficient to provide full-screen deflection.
signals of more than 25 volts (dc plus peak
ac). Should fault conditions occur however,
the instrument is protected for application
of input signals up to 100 volts (de plus
With no signals applied to the +Z INPUT connector,
the intensity of the display is controlled only by the
front-panel INTENSITY contro!. To contro! the display
intensity with an externally applied signal, set the
INTENSITY control to about midrange, and apply the
input signal to the +Z INPUT connector.
Exercise care in establishing the correct
display intensity; a high-amplitude Z-Axis
input signal, combined with an excessively
high setting of the INTENSITY control, may
damage the crt phosphor.
The input signal required for maximum display
intensity, through the +Z INPUT connector, is set at
the factory for +1 volt, or less. The input signal
required to visually cut off the display intensity is set
at the factory for -1 volt, or less. The best transient
response of the Z-Axis Amplifier is achieved when the
input signal is the minimum required to provide the
desired intensity change.
