d. Use the CH 2 VERTICAL POSITION control to align
the bottom of the displayed waveform to the graticule line
three divisions below graticule center.
c. Set the Calibration Generator STD AMPLITUDE out-
put level to 0.5 V.
b. Connect the Calibration Generator STD AMPLI-
TUDE output to the CH 2 OR Y input connector via a 50 Q
cable. Do not use a termination.

Bandwidth.
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:
o. Disconnect the test setup.
n. Repeat parts c through j, using the cursors to meas-
ure the CH 1 waveform. Use the CH 2 VOLTS/DIV control
instead of CH 1's for part i.
m. Return both VOLTS/DIV controls to 100 mV.
I.
Select TRIGGER SOURCE and set CHAN 1:2 to 2.
k. Move the cable to CH 2.
j. Repeat parts e through h (using 10.00 mV as the
limit for part h) to check 150 MHz Channel Isolation.

i.
Change the CH 1 VOLTS/DIV control to 100 mV,
increase the generator frequency to 150 MHz, and re-
adjust the output level for a 5-division display. Return the
CH 1 VOLTS/DIV control to 50 mV.
h. CHECK-That the cursor readout (upper right
corner of display) indicates 5.00 mV or less.
g. Use the CURSOR/DELAY control to align this cur-
sor to the top of the CH 2 waveform. Take care to use the
same reference points (top edge, bottom edge, or center)
of the waveform and cursor as in part e.
f. Press CURSOR/SELECT to enable the alternate
cursor.
e. Using the CURSOR/DELAY control, align the mov-
able cursor (segmented) to the bottom of the CH 2
waveform.
d. Set the CH 1 and CH 2 VOLTS/DIV controls to
50 mV.
c. Set the generator frequency to 100 MHz and adjust
the output level for a 5-division display.
b. Connect the Leveled Sine-wave Generator to the
CH 1 OR
X
input connector via a 50 !1 BNC cable.

traces will be centered
vertically. DO NOT adjust the CH

POSI-
TION controls during the remainder of this Channel
Isolation check to avoid exceeding the dynamic
range of the CH
