Figure 5-6 Ripple and noise rms measurement test setup
Peak-to-peak measurement
The peak-to-peak measurement is particularly important for applications where
noise spikes could be detrimental to a sensitive load, such as logic circuitry.
To measure the ripple and noise of the peak-to-peak value on each output supply
output:
1 Connect the test equipment across the output of the +20 V supply as shown in
Figure 5-6 , but replace the true rms voltmeter with the oscilloscope.
2 Turn on the supply and push +20 V METER switch.
3 Turn up output voltage to the full rated value.
4 Set the oscilloscope to AC mode and bandwidth to 20 MHz.
5 Check that the peak-to-peak noise is less than 1.5 mV.
6 Repeat for the remaining supply outputs.
