Connect outputs to
oscilloscope
1.
Use appropriate cables to connect the front panel BNC and Type N outputs to
an oscilloscope.
2.
Set the oscilloscope timebase to 50 ns/div and vertical sensitivity for
200 mV/div with DC coupling and 50
Ω
input impedance.
3.
Check that the displayed cycle period is 100 ns (2 divisions).
4.
Check that the displayed amplitude is 630 mV

.
NOTE.
The displayed amplitude will be 630 mV if the oscilloscope input is not
set for 50
Ω
.
Basic functional check
Do the following after connecting to an oscilloscope to check that the information
shows as expected on the display screen and that you can adjust the parameters
and navigate the menus properly.
