6 53220A/53230A Math, Graphing, and Data Logging
Note that histograms and math functions (e.g. statistics, scaling, limits, etc.)
can be used simultaneously with the same measurement data.
Viewing Histograms
At power-on or when the front panel
Preset
key is pressed, numeric data is dis-
played. 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 trigger-
ing 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.
