HIStogram:DATa?
Description
This query--only command returns an ASCII comma --separated list of
histogram data numbers. This command returns 200 values for vertical
histograms and 500 values for horizontal histograms.
Note: You must set the histogram state to ON before sending this
query or the system will generate an error indicating: ”Source wave-
form is not active”.
The Histogram:DATa? query corresponds to the Histogram Data (CSV)
controls included in the oscilloscope user interface. To find these con-
trols, select either Edit > Copy > Setup > Measurements tab or the File
> Save As > Histogram button.
This command returns only histogram data values separated by commas
on a single line. The CSV file created by the user interface actions indi-
cated above, writes out a line for each histogram data point, and con-
tains the time relative to the trigger, a comma, and the histogram value.
