5. Set the oscilloscope as follows:
a. 1 mV/division
b. 1 M  input resistance
c. 20 MHz bandwidth (BW) limit
d. AC Coupled
e. Auto-trigger
f. 1 ms/div
g. Set to measure Vp-p and VRMS
6. Set the oscilloscope probe to 1X mode.
7. Set the DUT to the 100% FS output voltage.
8. Set the DUT to the 100% FS output current.
9. Turn the DUT output on.
Do not touch the load resistor. The load resistor may become hot enough to cause burns.
10. Enter the oscilloscope measurements into the Voltage noise at 7 MHz (on page B-10) table for
checking Noise at 7 MHz.
