Viewing histograms
At power-on or when the front panel Preset key is pressed, numeric data is
displayed. Remotely, histograms can be displayed by changing the display mode
using the command:
DISPlay[:WINDow]:MODE {NUMeric|HISTogram|TCHart}
DISPlay[:WINDow]:MODE? (query form)
The Graph key followed by the Histogram softkey enables and automatically starts
histograms from the front panel. Histograms can also be turned off from the
softkey menu.
Remotely, a reset (*RST) or instrument preset (SYSTem:PRESet) does not change
the display mode.
Histograms correspond to readings in reading memory - starting at the time the
histogram is enabled and ending when the product of the trigger count
(TRIGger:COUNt) and sample count (SAMPle:COUNt) is reached. If triggering is
continuous (i.e. internal), the histogram continually updates from the point it was
enabled.
Figure 6-6 describes the information provided in a typical histogram window.
