MARKER Menu
PEAK SEARCH:
Opens the
“MARKER PEAK SEARCH Menu” on page 2-27
SELECT:
Turns on the selected marker if it is off or makes it the active marker if it is
already turned on. Pressing the MARKER menu button for the first time will turn on
Marker 1 as a normal marker at the center of the time display, and open the MARKER
menu. Pressing the MARKER menu button thereafter opens the MARKER menu to the
current active marker. When a marker is turned on, it is a normal marker positioned at the
center of the time display on the active trace.
ENABLED:
Enables the selected marker. When the toggle is off, the marker is disabled
and not shown on the screen.
TIME:
Displays the marker time value. For delta markers, the time value is relative to the
reference marker. Change the marker time position by dragging it to the desired location.
You can also change the marker time value by pressing the TIME button and changing it
manually using the keypad controls.
AMPLITUDE:
Displays the current marker amplitude. When the marker mode is set to
Normal or Delta, the amplitude is set by the trace. In that case, the amplitude is not
settable by the user. The button is grayed out, but the value is still updating with every
sweep. If the marker is a Fixed marker, the amplitude value can be changed by dragging
the marker to the desired location or by directly entering the amplitude using the keypad
control.
MODE:
Select marker preference:
• Normal:
A Normal marker is also known as a tracking marker. The time value is
fixed but the amplitude value varies from sweep to sweep.
• Delta (Δ):
A Delta (Δ) marker displays the delta time value and amplitude between
itself and a reference marker. If Marker 1 is selected to be a Delta marker, then
Marker 2 is turned on as a reference marker for Marker 1 and it becomes a Normal
marker at the same location. The reference marker can then be switched to a Fixed
marker if desired.
• Fixed:
A Fixed marker has a fixed amplitude and fixed time, which are defined by
the user and not related to the trace or sweep data.
FUNCTION:
Sets the function of the currently selected marker to None or Noise. For
more information about using marker functions, refer to
“Marker Functions” on page 2-28
DELTA REFERENCE:
Selects the Reference marker for a Delta marker. A Delta marker
cannot be its own reference. Only Fixed and Normal markers may be used as a reference
for Delta markers.
TRACE:
Selects the trace number to which the marker is currently attached.
MARKER TABLE:
Toggle on or off the marker table displayed below the screen.
REF LVL TO MARKER:
Sets the reference level to the currently active marker’s
amplitude value.
ALL MARKERS OFF:
Turns all markers off, but markers will retain their last time
position once re-enabled.
PRESET MARKERS:
Presets marker selections to default values.
