g. Rotate the CH 1 POSITION control full counter-
clockwise and hold until the waveform no longer moves
down screen.
f. CHECK-That the bottom of the waveform is within
+0.7 to
-0.4
division of the center horizontal graticule
line.
e. Rotate the CH 1 POSITION control full clockwise
and hold until the waveform no longer moves up screen.
d. Remove the 5X attenuator and connect the cable
directly to the CH 1 input.
c. Adjust the generator output level for a 4 division
display on screen.
b. Connect a 50 kHz reference frequency signal from
the Leveled Sine-Wave Generator to the CH 1 OR X input
connector via a 50
Q
BNC cable and a 5X attenuator.

a. Recall the Initial Front Panel Setting by performing
the following sequence: Select SAVE/RECALL SETUP,
press the menu button labeled RECALL (menu will
change), and then press the menu button labeled
1.
Make
the following changes to the front panel setup:
p. Disconnect the test setup.
o. Repeat parts d through k to check CH 2 using CH 2
control settings and menus.
n. Select VERTICAL MODE and set CH 2 on and CH 1
off.
m. Move the cable from the CH
1
OR
X
input to the
CH
2
OR
Y
input.
I.
Set the STORAGE ACQUIRE mode to NORMAL on.
4-10
k. Repeat parts d through i to check the LF Linearity
for the ENVELOPE mode. Discount the noise and the
envelope "fill" when performing parts g and i and use 1.84
and 2.16 divisions as limits for those parts.
j. Select STORAGE ACQUIRE and set ENVELOPEon.
i. CHECK-That the amplitude of the displayed
waveform is between 1.88 and 2.12 divisions.
h. Use the CH 1 POSITION control to align the bottom
of the waveform to the bottom horizontal graticule line.
g. CHECK-That the amplitude of the displayed
waveform is between 1.88 and 2.12 divisions.
f. Use the CH 1 POSITION control to align the top of
the waveform to the top horizontal graticule line.
e. Use the generator VARIABLE control to adjust the
waveform for exactly 2 vertical divisions on screen
(discount trace width).
d. Use the CH
1
POSITION control to center the
waveform vertically around the center horizontal graticule
line.
c. Set the Calibration Generator STD AMPLITUDE out-
put level to
0.2
V.
b. Connect the Calibration Generator STD AMPLI-
TUDE output to the CH
1
OR
X
input connector via a 50 Q
cable. Do not use a termination.
