s. Disconnect test setup.
q. Set the generator to produce a 15 kHz, 5 division
display.
r. Repeat parts d through n to check square-wave
flatness at 15 kHz.
p. Remove the lOX attenuator and reconnect the test
setup.
o. Set the CH 1 VOLTS/DIV control to 200 mV and set
the A SEC/DIV control to 10 IJ.s.
n. CHECK-Display front-corner aberrations are within
1 % (0.2 division or less). Exclude the first 20 ns immedi-
ately following the positive-going transition from the
measurement.
m. Move the cable from the CH2 input connector to the
CH1 input connector. Set the CHl VOLTS/DIV control to 5
mY.
I. First set the CH 2 VOLTS/DIV control to 50 mY,
then set CH 1 on and CH 2 off.
k. CHECK-Display front-corner aberrations are within
1 % (0.2 division or less). Exclude the first 20 ns immedi-
ately following the positive-going transition from the
measurement.
j. Install a lOX attenuator between the 50 Q cable and
the terminator and reconnect the setup.
i. Set the CH2 VOLTS/DIV control to 5 mY.
h. CHECK-Display front-corner aberrations are within
1 % (0.2 division or less). Exclude the first 20 ns immedi-
ately following the positive-going transition from the
measurement.
g. Move the cable from the CH 1 input connector to
the CH 2 input connector.
f. Set CH 2 on and CH 1 off.

e. CHECK-Display front-corner aberrations are within
1 % (0.2 division or less). Exclude the first 20 ns immedi-
ately following the positive-going transition from the
measurement.

d. Set the CH 1 VOLTS/DIV control to 50 mY.
c. Set the generator to produce a 60 Hz, five-division
display and use the CH 1 POSITION control to center the
display as required.
b. Connect the fast-rise, positive going square-wave
output to the CH1 input connector via a 50-Q cable and a
50-Q terminator. The square wave should step from -1 V
to 0 V.

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:
For this step, use a PG 506 Calibration Generator
(Item 2) listed in the equipmentrequiredat the begin-
ning of "ADDITIONAL VERIFICATlONS AND
CHECK"procedure.
7. Check Square-Wave Flatness
(TV Option 05 only).
NOTE
n. Disconnect the test setups.
m. Repeat parts h through k, aligning the cursor to the
CH 2 waveform instead of the CH 1 waveform.
I. Press the CURSOR FUNCTION button twice to
display the ATTACH CURSORS menu and set CH 2 on
for the displayed menu.
k. CHECK-That the Cursor Readout indicates a volt-
age ~ 150 mY.
j. Align the Voltage cursor to the bottom flat portion of
the CH 1 waveform.
