5. Set the oscilloscope as follows:

1 mV/division
 1 MΩ input resistance

20 MHz bandwidth limit

AC coupled

Autotrigger

1 ms/div

Set to measure V
p-p
and V
RMS
6. Set the DUT to the 100% full-scale output voltage.
7. Set the DUT to the 100% full-scale output current.
8. Turn the DUT output on.
9. Enter the oscilloscope measurements in the Voltage noise at 20 MHz (on page B-14) table for
checking noise at 20 MHz.
