c. Adjust the generator output fo r a 5-division display.
d. Preset High Freq Comp (R357) fu lly counter
clockwise.
e. ADJUST—High Freq Comp (C357) until ringing just
disappears on the fro n t corner.
f. A D JU S T -Lo w Freq Comp (R367) and Mid Freq
Comp (R366 and C366) fo r best flat top beyond 20 ns
from the corner.
g. ADJUST—R357 and C357 fo r best corner on the
first 20 ns o f the displayed signal.
h. Repeat parts f and g until no further improvement
is noted.
i. Set the CH 2 VO LTS/D IV switch to 0.1 V and repeat
parts f and g fo r best compromise w ith the 20-mV VO LTS/
D IV switch setting.
j. Disconnect the test setup.
12. A d ju st Channel M atching (C 1 6 7 ) and Check
B andw idth
a. Set:
VO LTS/D IV (both)
20 mV
SEC/DIV
20 jus
b. Connect the leveled sine-wave generator output via
a 50-J2 cable and a 50-S2 term ination to the CH 2 OR Y
input connector.
c. Set the generator output fo r a 5-division, 50-kHz
display.
d. Increase the generator frequency until the display
reduces to 3.5 divisions.
e. Move the signal from the CH 2 OR Y input connector
to the CH 1 OR X input connector. Set the VE R TIC A L
MODE switch to CH 1.
f. AD JU ST-C H 1 & CH 2 HF Match (C167) fo r a
vertical display amplitude o f 3.5 divisions.
Adjustment Procedure—2213 Service
g. Set both VO LTS /D IV switches to 2 mV.
h. Set the generator o utput amplitude fo r a 5-division,
50-kHz display.
i. Change the generator output frequency to the value
shown in Table 5-5 fo r the corresponding VO LTS/DIV
switch setting.

j. CHECK—Display amplitude is 3.5 divisions o r greater.
k. Repeat parts h through j fo r all indicated CH 1
VO LTS/D IV switch settings, up to the output-voltage
upper lim it o f the sine-wave generator being used.
I. Move the generator o utput signal from the CH 1
OR X input connector to the CH 2 OR Y input connector.
Set the VE R TIC A L MODE switch to CH 2.
m. Repeat parts h through j fo r all indicated CH 2
VO LTS/D IV switch settings up to the output-voltage upper
lim it o f the sine-wave generator being used.
n. Disconnect the test setup.
13. Check C o m m o n -M o d e R ejection R atio
a. Set both VO LTS/D IV switches to 20 mV.
b. Connect a 10-MHz, leveled sine-wave signal via a
50-L2 cable, a 50-17 term ination, and a dual-input coupler
to the CH 1 OR X and the CH 2 OR Y input connectors.
c. Set the generator o utput amplitude to produce a
6-division display.
d. Vertically center the display using the Channel 2
POSITION control. Then set VE R TIC A L MODE to CH 1
