c. Use the CH 1 VERTICAL POSITION control to
vertically center the display on the graticule.
d. CHECK—Ellipse opening is 0.1 division or less,
measured horizontally.
e. Set the CH 2 VERTICAL MODE on.
f. Set the generator for a 2 MHz, 6-division horizontal
display.
b. Connect a 50 mV standard-amplitude signal from the
Calibration Generator to the CH 1 OR X input connector
via a 50 $1 BNC cable.
c. CHECK—Signal display amplitude is 4.9 to 5.1 hor-
izontal divisions.
g. Set the CH 2 VERTICAL MODE off.
h. CHECK—Ellipse opening is 0.3 division or less,
measured horizontally.
i. Set the CH 2 VERTICAL MODE on.
d. Disconnect the test setup.
7. Check X-Axis Bandwidth.
a. Set the CH 1 Input Coupling to 50 fi DC.
b. Connect a 50 kHz signal from the Primary Leveled
Sine-Wave Generator to the CH 1 OR X input connector
via a precision 50 ft BNC cable.
c. Set the generator output for a 6-division horizontal
display.
d. Change the generator frequency to 3 MHz.
e. CHECK—Signal display is greater than 4.2 horizontal
divisions.
8. Check X-Y Phase Differential.
a. Set the Primary Leveled Sine-Wave Generator for a
1 MHz, 6-division horizontal display.
9. Check X-Axis Low-Frequency Linearity.
a. Set the Primary Leveled Sine-Wave Generator and
the CH 1 POSITION control for a 50 kHz, 2-division hor-
izontal display centered on the graticule.
b. Use the CH 1 POSITION control to align the left
edge of the signal with the left side vertical graticule line.
c. CHECK—Signal display is 1.8 to 2.2 divisions, meas-
ured horizontally.
d. Use the CH 1 POSITION control to position the right
edge of the signal on the right side vertical graticule line.
e. CHECK—Signal display is 1.8 to 2.2 divisions, meas-
ured horizontally.
f. Disconnect the test setup.
