(13) Reduce all outputs to minimum.
(14) Press corresponding pushbuttons for indications listed in (a) through (c) below:
(a) 20 MHz BW LIMIT off.
(b) TRIGGER SLOPE to + (positive) and TRIGGER COUPLING to AC.
(c) TRIGGER MODE to AUTO LVL, TRIGGER SOURCE to VERT CH 1.
(15) Set CH 1 VOLTS/DIV switch to 100 mV and A SWP SEC/DIV switch to 50 Ps
(knobs locked).
(16) Connect oscilloscope calibrator SOURCE/MEASURE CHAN 1 to TI CH 1 and
SOURCE/MEASURE CHAN 2 to TI CH 2 using 50 Ÿ feedthrough terminations.
(17) Set oscilloscope calibrator for a CHAN 1, LEVEL SINE mode output of 50 kHz
and adjust output amplitude for 0.35 division of display on TI.
(18) Adjust TRIGGER LEVEL control for a stable display at all settings listed in
table 12. If a stable display cannot be obtained, perform b below.
NOTE
Set A SWP SEC/DIV switch and press X10 MAG pushbutton
as necessary to obtain a well-defined display of test signal.
