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.
