Apply a +0.5V to +2.75V signal to the SMA connector marked IN. 5) Verify the output signal on the oscilloscope. Note: If you use a 50 terminated oscilloscope input, the output amplitude observed will be half that of the input, due to the voltage divider formed by the 49.9 back-terminating resistor (R1) and the oscilloscope input termination.
