e. Connect a 50-ohm cable from the UHF T connector
to the EXTERNAL TRIG. IN connector.
f. Rotate the LEVEL control to a point near 0 to obtain
a stable display, similar to Fig. 6-22.
g. Adjust the generator output for a 3-cm spacing hori
zontally, and center the display with the HORIZONTAL
POSITION control.

h. Check— For an optimum square wave with fla t lop,
similar to Fig. 6-22 (B).
i. Adjust C306 for an optimum square wave with flat
top. (See Fig. 5-21 for adjustment locations.)
j. Change the HORIZONTAL SENSITIVITY switch to .5
VOLTS/CM, and adjust the generator output for a 3-cm
display.
k. Check— For an optimum square wave with a fla t top,
as in step (i).
l
. Adjust C305B for best square wave with a flat top.
m. Change the SWEEP TIME/CM switch to .1 mSEC.
n. Check Square front corner on waveform, with over
shoot or rounding not exceeding 2% of the display am p li
tude. (See Fig. 6-23 for typical displays.)
o. Adjust C305C for waveform front cornor with mini
mum aberrations.
p. Change the HORIZONTAL SENSITIVITY switch to 5
VOLTS/CM.
q. Change the SWEEP TIME/CM to 2 mSEC, and adjust
the display for a horizontal deflection of 3 cm. Remove
attenuation as necessary to maintain a 3-cm display.
