4-56 Normal Marker Menu
SR785 Dynamic Signal Analyzer
Pressing [Marker Ref] changes from Off to Rel. and sets the Marker Offset to the current
Marker Position. [Marker Ref] again changes from Rel. back to Off.
Each display has its own Normal Marker X Offset. This entry field can be linked to both
displays using the [Link] key.
Command: MROX (?) d {, x}
Y-Rel
Set the Y Offset for the Normal Marker of the active display. Enter a new offset
numerically or adjust it with the knob.
When the Marker Rel Mode is Relative, the marker position is calculated relative to the
Marker Offset (X-Rel, Y-Rel). The Marker Offset location (if it is within the display) is
marked by a small flag shaped symbol.
The Marker Offset has no associated units. The relative calculation simply subtracts the
Marker Offset (in the display units) from the absolute marker position. Changing the
display units invalidates the Marker Offset. Re-enter the Marker Offset or use [Marker
Ref] to reset the Marker Offset in the new units.
Pressing [Marker Ref] changes from Off to Rel. and sets the Marker Offset to the current
Marker Position. [Marker Ref] again changes from Rel. back to Off.
Each display has its own Normal Marker Y Offset. This entry field can be linked to both
displays using the [Link] key.
Command: MROY (?) d {, x}
X-Rel
Set the X Rel Mode for the Normal Marker of the active display [Off, On].
When the Marker Rel Mode is Relative to the Marker Offset or Relative to the Other
Display, the marker Y value is shown relative to the offset or other display.
Choose On to show the marker X value relative to the offset or other display as well.
Choose Off to show the absolute marker X value. This is useful when making relative
amplitude measurements while still needing to read the marker X position in absolute
units.
Each display has its own X Rel Mode. This entry field can be linked to both displays
using the [Link] key.
Command: MXRL (?) d {, i}
