4.3.5 Bench Setup Diagram

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

Use the following connection procedure, refer to #SLUUBM2965.

  • First, make sure the output of the function generator and power supplies are disabled before connection.
  • Apply function generator channel-A on INL_IN-GND.
  • Apply function generator channel-B on INH_IN-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 GL LO-SH, minimizing the loop area as much as possible. Note the scope ground is connected to SH test point.
  • Apply oscilloscope channel-2 probes on GH LO-GND, minimizing the loop area as much as possible.
