Power Supply Setup

Figure 2 illustrates the necessary power connections for 3.3-V VCC-to-VEE operation.
• With supply 1 disabled, program supply 1 to 3.3 V with 100-mA current limit
• With supply 2 disabled, program supply 2 to 2 V with 100-mA current limit
(A) Connect supplies and board with banana cables as shown. This configuration is for nominal 3.3-V
testing. To configure other VCC-to-VEE voltages, program supply 1 to the proper range of 2.375 V to
3.8 V. Supply 2 remains fixed with 2-V offset from VCC to earth ground termination.
(B) With the signal generator disabled, program according to
Note, that the amplitudes and offsets are based on a single-ended signal.
