Sencore PS163 User Manual

CONTROLS
OFF-ON SWITCH
This switch controls the power applied to the unit.
The ON condition is shown by a pilot lamp directly
above the switch.
SCALE ILLUMINATION
Either the standard 10 x 10cm grid or the vector
grid may be illuminated for trace reference. The
vector grid is calibrated with 30 reference points to
show proper placement of the color vector “petal”’
pattern. An off position is also provided.
INTENSITY CONTROL
This control adjusts the brilliance of the trace.
Trace brilliance may vary somewhat during operation
of the PS163 when using the 5X expand at higher
frequencies. If the PS163 is to be operated under a
stand-by condition for any length of time, it is
recommended that the intensity be reduced to pre-
vent burning the face of the CRT.

just for sharpest trace in center of screen.
HORIZONTAL SYNC
This switch allows selection INT. A, INT B, LINE, or
EXT sources for sync information. EXT sync signal
is applied to the EXTERNAL TRIGGER input.
SYNC POLARITY
This switch selects the slope of the sync signal used
to trigger the time base. The POSITIVE position will
cause triggering on a positive going signal; the NEG-
ATIVE position will cause triggering on a negative
going signal.
SYNC LEVEL
This control functions in MANUAL TRIGGERED
HORIZONTAL SWEEP mode only. It is used to ad-
just the level of sync signal necessary to produce
sweep and provide a stable display.
LINE SWEEP PHASE
This control functions in the 60 cycle position of the
TIME BASE - FREQUENCY switch only. It is used
to adjust the phase of the internal 60 Hertz sine
wave applied to the horizontal amplifier for line
sweep.
HORIZONTAL POSITION
This control adjusts the horizontal position of the trace
in all functions except the VECTOR A+B VERT-
ICAL INPUT MODE. The CHANNEL B TRACE
position control will adjust the horizontal trace po-
sition in the VECTOR mode.
