Output noise verification
Periodic and random output deviations superimpose a residual AC voltage on the
DC output. This residual voltage is specified as the rms or peak-to-peak noise in
and is specified in the product data sheet.
1 Turn off the power supply using the AC line switch.
2 Connect a fixed load, differential amplifier, and an oscilloscope (AC coupled) to
the output as shown below.
3 Turn on the power supply using the AC line switch.
