f. CHECK—That a stable triggered display can be
obtained in AC and DC positions of A TRIGGER
COUPLING with adjustment of A TRIGGER LEVEL.
g. Set the low-frequency generator for a 2 division,
50 kilohertz display, then set A TRIGGER SOURCE to
EXT (100 millivolts at external input).
h. CHECK—Repeat part c.
i. Set CH 1 VOLTS/DIV to 0.1 V and set A TRIGGER
SOURCE to EXT 10.
j. Set the low-frequency generator for a 5 division,
50 kilohertz display (500 millivolts at inputs), then set CH
1 VOLTS/DIV to 0.5 V.
k. CHECK—Repeat part f.
1. Set CH 1 VOLTS/DIV to 10 mV and set A TRIGGER
SOURCE to EXT.
m. Set the low-frequency generator for a 5 division,
50 kilohertz display (50 millivolts at external input), then
set CH 1 VOLTS/DIV to 50 mV.
n. CHECK—Repeat part f.
o. Set A TRIGGER SOURCE to NORM, set CH 1
VOLTS/DIV to 5 mV, set TIME/DIV to 10 ms and set 100
OR 20 MHz BW control to 20.
p. Set the low-frequency generator for a 5 division,
60 Hertz display, then set CH 1 VOLTS/DIV to 50 mV.
q. CHECK—That a stable triggered display can be
obtained in DC, HF REJ and AC positions of A TRIGGER
COUPLING with adjustment of A TRIGGER LEVEL.
r. Set A TRIGGER COUPLING to LF REJ.
s. CHECK—That a stable triggered display cannot be
obtained with adjustment of A TRIGGER LEVEL.
t. Set CH 1 VOLTS/DIV to 5 mV and set A TRIGGER
COUPLING to AC.
5-10
u. Set the low-frequency generator for a 3 division,
60 Hertz display, then set CH 1 VOLTS/DIV to 50 mV.
v. CHECK—That a stable triggered display can be
obtained in AC and DC positions of A TRIGGER
COUPLING with adjustment of A TRIGGER LEVEL.
w. Set the low-frequency generator for a 2 division,
60 Hertz display, then set A TRIGGER SOURCE to EXT
(100 millivolts at external input).
x. CHECK—Repeat part q.
y. Set A TRIGGER COUPLING to LF REJ.
z. CHECK—Repeat part s.
aa. Set A TRIGGER COUPLING to AC.
ab. Set the low-frequency generator for a 1 division,
60 Hertz display (50 millivolts at external input).
ac. CHECK—That a stable triggered display can be
obtained in AC and DC positions of A TRIGGER
COUPLING with adjustment of A TRIGGER LEVEL.
ad. Disconnect ail test equipment.
NOTE
Use a sine-wave generator with an output of
100 megahertz and below for the following parts.
ae. Connect the sine-wave generator output cable to a
BNC female-to-BNC female adapter, to a BNC T-
connector, to two 18-inch 50-ohm BNC cables. Connect
an 18-inch cable through a 50-ohm termination to CH 1
input and connect the other 18-inch cable through a 50-
ohm termination to A TRIGGER external input.
af. Set TIME/DIV to 0.5
ag. Set the sine-wave generator for a 2 division,
3 megahertz display (100 millivolts at external input).
ah. Set A TRIGGER COUPLING to HF REJ.
