CH 1 and CH 2 Input COUPLING AC
Connect leveled sine-wave generator (SG 503) output to the CH 1 and
CH 2 inputs via a 50 f l BNC coaxial cable, a 50 H BNC termination,
and a BNC dual-input coupler.
Position trace to center horizontal graticule line.
Set leveled sine-wave generator output for two-division signal at
50 kHz.
Set:
CH 1 VOLTS/DIV 0.1 V
CH 1 POSITION Fully CW (clockwise)
CHECK—that the bottom of the waveform is at least one division above
the center horizontal graticule line.
Set CH 1 POSITION fully CCW.
CHECK—that the top of the waveform is at least one division below the
center horizontal graticule line.
Set:
CH 1 POSITION 12 o’clock
VERTICAL MODE CH 2 (CH 1 off)
CH 2 POSITION Fully CW
CHECK—that the bottom of the waveform is at least one division above
the center horizontal graticule line.
Set CH 2 POSITION fully CCW.
CHECK—that the top of the waveform is at least one division below the
center horizontal graticule line.
