2.3Input and Output Setup

1)Ensure that JU3, JU4, and JU1 are not installed (open circuit).

2)Set the function generator to generate a 1 MHz, ±0.5 V (1 VPP) sine wave with no dc offset.

3)Turn off the function generator before proceeding to the next step.

4)Using a BNC-to-SMA cable, connect the function generator to J1 (VI+) on the EVM.

5)Using a BNC-to-SMA cable, connect the oscilloscope to J3 (VO±) on the EVM.

6)Using a BNC-to-SMA cable, connect the oscilloscope to J4 (VO+) on the EVM. Set the oscilloscope to 0.5 V/division and a time-base of 0.2 ∝s/division.

Note: The oscilloscope must be set to use a 50-Ωinput impedance for proper results.
