Performance Check Procedure— 2236 Service
k. CHECK— The readout is stable and accurately dis
plays the input signal frequency.
l
. Set:
VERTICAL MODE
CH 2
A&B INT
CH 2
m. Move the cable from the CH 1 OR X input connector
to the CH 2 OR Y input connector.
n. Repeat parts c through k for Channel 2.
o. Set the X I0 Magnifier to On (knob out).
p. Set the generator to produce a 60-MHz, 1.2-division
display.
q. Repeat parts e through g.
r. Increase the generator output to produce a 1.5-divi
sion display.
s. Repeat parts i through k.
t. Set:
VERTICAL MODE
CH 1
A&B INT
VERT MODE
u. Move the cable from the CH 2 OR Y input connector
to the CH 1 OR X input connector.
v. Repeat parts p through s for Channel 1.
w. Set the A SEC/DIV switch to 0.05 ^s.
x. Set the generator to produce a 100-MHz, 1.5-division
display.
y. Repeat parts e through g.
z. Increase the generator output to produce a 2.0-
division display.
aa. Repeat parts i through k.
ab. Move the cable from the CH 1 OR X input connector
to the CH 2 OR Y input connector. Set the VERTICAL
MODE switch to CH 2.
ac. Repeat parts x through aa for Channel 2.
ad. Disconnect the test equipment from the instrument.
2. Check External Triggering
a. Set:
VERTICAL MODE
CH 1
X I0 Magnifier
Off (knob in)
A SOURCE
EXT
b. Connect a 40-mV, 10-MHz leveled sine-wave signal
via a 50-12 cable and a 50-12 termination to the EXT INPUT
connector.
c. Push in and hold the TRIG VIEW button.
d. CHECK— Stable display can be obtained by adjusting
the A TRIGGER LEVEL control for each switch combination
given in Table 4-5. Then release the TRIG VIEW button.
e. Increase the generator output voltage to 50 mV.
f. CHECK— The readout is stable and accurately dis
plays the input signal frequency.
g. Set the generator output voltage to 150 mV and the
frequency to 60 MHz. Set the X I0 Magnifier to On (knob
out).
h. Repeat parts c and d.
i. Increase the generator output voltage to 160 mV.
j. CHECK— The readout is stable and accurately dis
plays the input signal frequency.
k. Set the generator output voltage to 250 mV and the
frequency to 100 MHz.
