from a reference marker. Its absolute Y-axis value is then the value of the trace point at that X-axis value.

Sets the control mode for the selected marker to Fixed. A fixed marker is fixed in the sense that it stays
where you place it. It can be directly moved in both X and Y. It can be moved with a Peak Search. It can
also be indirectly moved by re-zeroing the delta if it is a relative marker. If it is moved, it again becomes
fixed at the X-axis point it moved to and it has a Y-axis result that it took on when it moved there. If a
Normal or Delta marker is changed to Fixed it becomes fixed at the X-axis point it was at, and with the
Y-axis result it had when it was set to Fixed.
In Fixed mode the marker result shows:
• If no Marker Function is on, the absolute X-axis and Y axis value of the marker
• If a Marker Function is on, the X-axis value and the Y-axis function result the marker had when it
became fixed.

Example :CALC:MARK:MODE DELT sets marker 1 to Delta.

State Saved The marker control mode (Normal, Delta, Fixed, Off) and X-axis value are
saved in instrument state
