Marker Commands

Command

:MARKer:MODE[?] {OFF | MANual | WAVeform |

MEASurement | HISTogram | TDRTDT}

Sets the marker mode.

Command

:MARKer:PROPagation[?] {DIELectric | METer | FEET}

Sets the propagation velocity for TDR and TDT measurements. The

propagation may be specified as a dielectric constant or in meters per second

or feet per second. The value is used to determine the distance from the

reference plane in TDR and TDT marker measurements.

Dielectric constant or propagation value.

Command

:MARKer:REFerence[?] {TRIGger | REFerence}

Specifies the marker reference for TDR and TDT style markers. If the

reference is TRIGger, then all horizontal axis marker measurements are made

with respect to the trigger point. If the reference is REFerence, then all

horizontal axis marker measurements are made with respect to the reference

plane. You must perform a normalization and reference plane calibration

before using a reference plane reference. This feature is available only for

TDR and TDT applications.
