10. Oscilloscope Trace Alignment
a. Performance Check
(1) Disconnect input signal from TI.
(2) Adjust oscilloscope HORIZ GAIN control for maximum horizontal deflection of
trace with both edges of trace visible on oscilloscope. If trace is not centered both vertically
and horizontally, perform b below.
(1) Adjust R32 to center trace horizontally (R).
(2) Adjust R34 to center trace vertically (R).
11. Horizontal Sweep
a. Performance Check
(2) Set HORIZONTAL SWEEP INPUT switch (rear of TI) to EXT and rotate
