Performance Check Procedure
12. Vertical POSITION Range (all channels)
a. Set:
A SEC/DIV 0.1ms
VERTICAL MODE CH 1 (ADD off)
CH 1 VOLTS/D1V 1 V
CH 2 INVERT Off
SCOPE BW Off
CH 1 and CH 2 Input COUPLING AC
b. Connect leveled sine-wave generator (SG 503) output to the CH 1 and
CH 2 inputs via a 50
Cl
BNC coaxial cable, a 50 H BNC termination,
and a BNC dual-input coupler.
c. Position trace to center horizontal graticule line.
d. Set leveled sine-wave generator output for two-division signal at
50 kHz.
e. Set:
CH 1 VOLTS/DiV 0.1 V
CH 1 POSITION Fully CW (clockwise)
f. CHECK—that the bottom of the waveform is at least one division above
the center horizontal graticule tine.
g. Set CH 1 POSITION fully CCW.
h. CHECK—that the top of the waveform is at least one division below the
center horizontal graticule line.
I. Set:
CH 1 POSITION 12 o'clock
VERTICAL MODE CH 2 (CH 1 off)

j. CHECK—that the bottom of the waveform is at least one division above
the center horizontal graticule line.
k. Set CH 2 POSITION fully CCW.
l. CHECK—that the top of the waveform is at least one division below the
center horizontal graticule line.
