4.2.6 Bench Setup Diagram
The current bench setup diagram includes the function generator and oscilloscope connections.
Follow this connection procedure, Figure 2 can be used as a reference.
1. Ensure the output of the function generator and voltage sources are disabled before connection.
2. Connect the function generator channel 1 to TP7 (INA) and TP5 (GND), see Figure 2 .
3. Connect the function generator channel 2 to TP8 (INB) and TP6 (GND), see Figure 2 .
4. Power supply 1: Connect the positive lead to TP1 (VCCIN). Connect the negative lead to TP2 (GND).
5. Power supply 2: Connect the positive lead to the current meter input of DMM1, and connect the current
meter output of DMM1 to TP16 (VDDAIN). Connect the negative lead directly to TP18 (GNDA).
6. Power supply 3: Connect the positive lead to the current meter input of DMM2, and connect the current
meter output of DMM2 to TP21 (VDDBIN). Connect the negative lead directly to TP23 (GNDB).
7. Connect the oscilloscope channel 1 probe to TP17 (V_GA) and TP15 (GNDA). The probe loop area
should be minimized.
8. Connect the oscilloscope channel 2 probe to TP22 (V_GB) and TP20 (GNDB). The probe loop area
should be minimized.
