MOST150 OPHY MEASUREMENT PREPARATION

Before beginning any test or data acquisition, the oscilloscope must be warmed for at least 20 minutes.

Calibration is automatic under software control and no manual calibration is required.

This procedure will be run again if the temperature of the oscilloscope changes by more than a few

degrees.

QPHY-MOST150O TEST CONFIGURATIONS

Configurations also include variable settings and limit sets, not just test selections. See the QPHY-

MOST150o Variables section for a description of each variable value and its respective default value.

All Tests [demo]

This configuration runs a demonstration of all of the supported compliance tests. All variables are set to

default. Saved waveforms are used.

All Tests [differential and optical probe]

This configuration assumes a differential probe is used for the electrical test points and an optical probe

(O/E) for the optical test points.

All Tests [differential probe only]

This configuration assumes a differential probe is used for the all test points.

All Tests [direct connections]

This configuration assumes direct connections (SMA cables) are used for all test points.

All Tests [optical probe only]

This configuration assumes direct connections (SMA cables) are used for the electrical test points and an

optical probe (O/E) for the optical test points.
