NOTE
If TI does not perform as specified, perform adjustments as
indicated in Section IV.
a. Select oscilloscope calibrator CHAN 1, and connect oscilloscope calibrator
SOURCE/MEASURE CHAN 1 output through a 50Ω feedthrough termination to a BNC
dual input coupler. Connect one end of BNC dual input coupler to the TI CH1 input and
remaining end of BNC dual input coupler unconnected.
