The bench setup diagram includes the function generator and oscilloscope connections.

Use the following connection procedure, refer to Figure 5-1.

• First, make sure the output of the function generator and power supplies are disabled before connection.
• Apply function generator channel-A on HI_IN-GND.
• Apply function generator channel-B on LI_IN-GND.

• Ensure shunt is installed on J1 pins 1-2 to connect EN to VDD.

• Ensure shunt is installed on J2 pins 1-2 to connect HS to GND.

• Power supply #1: apply positive lead to current input of DMM #1 and current output of DMM #1 to test point VCC; apply negative lead to test point GND.
• Apply oscilloscope channel-1 probes on HO LD-HS, minimizing the loop area as much as possible. Note the scope ground is connected to HS test point.
• Apply oscilloscope channel-2 probes on LO LD-GND, minimizing the loop area as much as possible.
