Functional Test Procedures
5.
Verify that the Main time base operates:
Con
fi
rm that the following statements
are true:
One period of the TDR clock waveform (a square wave) is about
fi
ve
horizontal divisions on-screen.
Rotating the Horizontal
SCALE
knob clockwise expands the
waveform on-screen (more horizontal divisions per waveform period),
counterclockwise rotation contracts it, and returning the horizontal scale
to 1
μ
s/div returns the period to about
fi
ve divisions.
Leave the time
base set to 1
μ
s/div.
Rotating the horizontal
POSITION
knob moves the waveform left and
right on the screen.
NOTE.
The signal will not move past the minimum position setting.
6.
Set up the Mag1 time base:
a.
Push the Horizontal View
MAG1
front-panel button. The Mag1 time base
view displays below the Main time base view.
b.
Set the Horizontal
SCALE
to
1
μ
s/div
. The horizontal scale readout
is in the Control bar at the bottom of the graticule and now shows the
horizontal scale value of the Mag1 time base view.
7.
Verify that the Mag1 time base operates:
Con
fi
rm the following statements.
The Mag view brackets on the Main View waveform
(top graticule)
are a
full-screen width apart (10-divisions) as shown in the following
fi
gure.
One period of the internal clock signal (a square wave) in the Mag view
(
bottom graticule
) is about
fi
ve horizontal divisions on-screen as shown in
the following
fi
gure. (Matches the waveform in the top graticule.)
Rotating the Horizontal
SCALE
knob clockwise to
500 ns/div
expands
the waveform
in the bottom graticule
to double the period (about 10
horizontal divisions per waveform period); rotating the Horizontal
SCALE knob counterclockwise returns the Horizontal scale setting to
1
μ
s/div
returns the waveform period to about
fi
ve divisions. Leave the
Horizontal Scale set to
1
μ
s/div
.
