5) The square wave rise time is measured using the scope.
a) Disconnect the DS360 from the spectrum analyzer. Connect the + BNC of the DS360 to CH A
of the scope. Set the scope CH A to 2µs/div, 5 V/div, with triggering on CH A.
b) Press
[∧] (function up) until square wave is selected.

c) Measure the 10% - 90% rise time of the squarewave. Repeat for the fall time. Record the
results on the test record.
d) Connect the - BNC of the DS360 to the scope CH A and repeat step 5c) for the - channel.
6) This completes the waveform tests.
