(e) BLUE SHIFT.
(f) REF LEVEL, 0, kHz dBX.
(10) Use TI CENTER/MARKER FREQUENCY knob to align markers on graticule
lines.
(11) Check alignment of markers to graticule lines over TI center eight divisions. If
alignment error is not within limits specified in first row of table 5, perform b below.
(12) Repeat technique of (8) (a) through (d) and (9) through (11) above for remaining
TI settings and oscilloscope calibrator outputs in table 5 below. If TI alignment is not
within limits specified in table 5, perform b below.
NOTE
