(16) Set TI OUTPUT to OFF and disconnect equipment set-up.
b. Adjustments. Perform entire alignment procedure in paragraph 11 below.
9. Time Marker and Pulse Width Accuracy
a. Performance Check
NOTE
To minimize errors associated with precise trigger levels,
hysteresis compensation should be performed on frequency
counter before measuring TI pulse width. Ensure that nothing
is connected to frequency counter. Press AUX MENU, with the
SELECT/SET key, select CAL HYST then press ENTER.
REFERENCE IN.
(2) Connect TI CH 1 output to frequency counter INPUT A through active head.
