Using the THS4130 EVM
2.3 Input 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
µs/division.
Note: The oscilloscope must be set to use a 50-Ω input impedance for
proper results.
