7623/R7623
Service
1.
INTENSITY—
Controls the brightness of
the
display.
2.
READOUT—
Turns on the
Readout
dis
play,
and controls the brightness of the
Readout display.
3.
FOCUS—Screwdriver
adjustment provides
adjustment
for optimum display definition.
4. GRATICULE
ILLUM—Controls
graticule
illumination.
5. BEAM
FINDER-When pressed the display
is
limited to within the graticule
area.
6.
Camera Power-Three
pin connector on the
CRT bezel,
(top) +15 volt
power source,
(middle)
receives remote single sweep reset
signal from compatible camera system, and
(bottom) ground
pin.
7. VERT MODE—Selects vertical
mode of operations.
o
«X
10.
NON-STORE—Non-store
operation.
LEFT:
Signals from the left plug-in compartment
are dis
played.
ALT: Signals from both
vertical plug-in
compartments are
displayed (dual trace). Display is switched from one vertical
to the
other after each sweep.
ADD:
Signals
from both vertical plug-in compartments are
algebraically
added,
and the sum is
displayed.
11. VAR-PERSIST-Variable persistence storage mode. The AUTO
VIEW
TIME
or PERSISTENCE control
setting, controls
the
retention
of
the stored display.
12. FAST—For
storing fast signals.
13. MULTI-TRACE-IMULTI-FAST
in
early instruments)-For stor
ing multiple
fast
signals. For each new signal to be
stored the
ERASE
(PREP
IN MULTI TRACE
FAST) must be
pressed.
CHOP: Signals from
both vertical compartments are dis
played
(dual trace). Display switches from the left vertical
compartment
signal to the right vertical compartment signal
at
a one megahertz rate.
RIGHT: Signals
from the right
plug-in
compartment are
displayed.
8.
TRIG SOURCE—Selects the source of the internal trigger signals
for
the horizontal compartment.
LEFT:
Trigger signals are from
the left vertical plug-in
compartment
only.
VERT
MODE: Trigger signals
are from the vertical compart
ment
being displayed except in the CHOP and ADD modes;
then
the trigger signal is the
algebraic sum of the trigger
signals
from
the left and right
plug-in compartments.
RIGHT: Trigger
signals
are from
the right
vertical plug in
compartment
only.
14.
INTEG—
For
storing
very fast repetitive signals.
15. BI STABLE—
For storing slow signals for long
periods of time.
16.
SAVE—
Prevents
accidental erasure of the stored display.
17. SAVE INTEN
(STORED
INTEN in early instruments)-Controls
the
brightness
of the stored display in the Save Mode.
18.
AUTO
ERASE-Automatically erases the stored display. AUTO
VIEW TIME setting controls the time between erase cycles.
19. AUTO
VIEW TIME-IVIEW TIME in early instruments)-
Controls the
time between erase cycles in the Auto Erase Mode.
20.
MAN
ERASE—Erases
the stored display.
21. STORAGE
LEVEL-(LEVEL
in
early instruments)—Controls
the
writing rate
in the
FAST and BI STABLE storage modes.
Controls
the writing rate and brightness of the
stored display
in
the
Variable
persistence Mode.
9.
POWER—
Switch and indicator;
switch turns on instrument, and
the indicator is on when the instrument is
connected to a power
source
and turned
on.
22.
CALIBRATOR—Positive going square wave or DC voltage
selected by changing an internal jumper. Output
voltage at pin
jacks
(4 V.
0.4 V and 40 mV).
