6. Set the signal s
ource to 240 MHz and 40 mV as shown in the test record.
NOTE. To provide consistent results, set the signal source frequency such that the
zero crossing does not occur at the beginning or end of the record.
7. Set the Horizontal Scale to 4nsper division.
8. Set the Vert
ical Scale to 5mVper division.
9. Record the Std Dev value as follows:
a. Push the side-bezel Reset Statistics button.
b. Push the Menu button to remove the side-bezel menu.
c. Wait five or 10 seconds for the oscilloscope to acquire all of the samples.
d. Verify that the Std Dev is less than the upper limit shown in the test record.
e. Enter t
he reading in the test record.
10. Repeat steps 6 through 9 for each setting combination shown in the test record.
11. Repeat the procedure for all remaining c hannels as follows:
a. Push the front-panel button to deselect the channel that you have already
tested.
b. Connect the signal source to the input for the next channel to be tested.
