12. Horizontal Linearity Accuracy
NOTE
If TI does not perform as specified, perform adjustments as
indicated in SECTION IV.
a. Connect oscilloscope calibrator SOURCE/MEASURE CHAN 1 output to TI CH 1
INPUT, and SOURCE/MEASURE CHAN 2 output to TI CH 2 INPUT.
b. Set oscilloscope calibrator for MARKER output listed in row one of table 14.
c. Rotate CH 1 VOLTS/DIV knob for 500 mV indications on crt display and rotate
HORIZONTAL A AND B SEC/DIV knob for A and B SEC/DIV settings listed in row one
of table 14.
d. Rotate TRIGGER LEVEL knob as necessary for triggered display.
e. Rotate HORIZONTAL A AND B POSITION knob to align 1st marker with 1st
graticule line. Adjust oscilloscope calibrator knob located under the EDIT FIELD key to
align 11th marker with 11th graticule line. Markers will be within display tolerance listed
in table 14 for the remaining vertical graticule lines between 1st and 11th vertical graticule lines.
f. Repeat e above for remaining rows in table 14.
