DC Load Ripple and Noise
Use an oscilloscope to check the DC Load Ripple and Noise on the pins of the
1.Set up the oscilloscope as follows:
Bandwidth Limit | 20 MHz |
Input Coupling | AC |
Volts/Division | 10 mV/div |
Time Base | 1 s/div |
Trigger Mode | Auto |
Acquisition Mode | Peak Detect |
2.Connect a ground lead (less than one inch) to the 1X oscilloscope probe (P6101B).
3.Connect the probe to Pin 1 of the
4.Check that
5.Check the remaining voltages in Table 5±1.
