- To display the rectified AC waveforms for half wave rectification and full wave rectification with and without filtering.
- Rectification assembly, consisting of:
Connect the circuit as shown in the picture. The following scope settings are recommended:
Channel 1 (connected to SC4 output to the rectifier board transformer)
Channel 2 (connected across the load)
Sweep speed = 5 ms/div
Turn on the scope and SC4 power supply. Set the SC4 to about 30 volts. Start with:
Use the scope's horizontal position controls to position the two waveforms for easy comparison.
Next use the switches on the rectification demonstrator to show:
Note scope connections.
The 10X probe is connected to the higher voltage input side of the transformer and the 1X leads connected to the lower voltage load. Note that both the isolation transformer within the SC4 power supply and the step down transformer on the rectifier board prevent "ground loop" problems with respect to the scope connections.
