) to EXT TRIG connector (input 1.0 V peak at 2.0 V peak-to-
V peak).
c. Connect the output of the sine-wave generator, with a
frequency of 1 kHz, to the back panel EXT IN connector.
Increase the output for a full 1 0-division sweep.
d. Check the output peak-to-peak voltage level of the
generator. Output should equal 20 V, ± 2 V peak-to-peak
(10 V ±1 V peak).
NOTE
A variable voltage source can be used in lieu o f the
sine-wave generator to check external sweep
operation.
e. Disconnect and remove the test equipment. Return
TIME/DIV to AUTO.
