The ‘Marker’ softkeys allow you to position markers on individual bins within
the histogram, and if desired, lock the relative distance between the markers.
When locked together, moving either Marker1 or Marker2 with the front panel
knob or using [Shift] followed by a bin number, also moves the other marker
while maintaining the distance between the two. The data corresponding to
the marker positions is shown above the histogram window.
Zoom determines the number of bins displayed by increasing the resolution at
the center region of the histogram. Each time the zoom is adjusted, the
X Min and X Max indices (Figure 6-6) are changed to show the current bin
range.
Pan scans the histogram (left or right) once a zoom percentage has been set. By
moving the Pan window, regions of interest can be brought into view; and
Zoom used again to expand the region. Pan, used interchangeably with Zoom in
this manner, maintains the zoom percentage.
Show All restores the histogram window to the total number of bins specified -
including the outer bins, and resets the zoom and pan.
Histogram Data in Numeric Form
Data describing the histogram is available in numeric form through either of
two query commands.
CALCulate2:TRANsform:HISTogram:ALL?
NOTE
For marker, zoom, and pan adjustment the decimal position (i.e. 100's, 10's, 1's)
highlighted by the arrow keys sets the amount of movement (coarse or fine) for
each tick of the rotary knob.
