R8 is known as the attenuation resistor, and is used to attenuate the output by setting the top half of a voltage divider circuit, with the bottom half supplied by the load, such as an oscilloscope’s internal termination. It is not advisable to populate with a low value resistor as the TLV3601 output cannot drive such a load as the amount of current sourced would be significant. A 1 kΩ resistor is recommended for this footprint which, coupled with a scope's internal 50 Ω termination creates an attenuation factor of 1:21 which can be rectified using oscilloscope settings. A high speed probe may be used for measurement of the output, but rise and fall times may be limited.

Two types of output connections are supplied depending on the needed configuration. J5, an SMA connector, can be populated or J10, a two-pin jumper, can be populated if using an active probe. If measuring the output and input (via input sense connections J3 and J4), it is recommended to use length matched cables on the output and sense lines to minimize distortion issues.
