next-to-last time bucket on the right side of the screen. Time buckets without data
return 0. The time values for each data point correspond to the position of the data
point in the data array. These time values are not transmitted.
AVERage Data
AVERage data consists of the average of the first n hits in a time bucket, where n is
the value returned by the :ACQuire:COUNt query (see
). Time buckets
that have fewer than n hits return the average of the data they do have. If a time
bucket does not have any data in it, it returns 0.
This data is transmitted over the interface linearly, starting with time bucket 0 and
proceeding through time bucket n-1, where n is the number returned by the
:WAVeform:POINts? query (see
). The first value corresponds to a point
at the left side of the screen and the last value corresponds to one point away from
the right side of the screen. The maximum number of points that can be returned
in average mode is 1000 unless ACQuire:COUNt has been set to 1.
PEAK Data
Peak detect display mode is used to detect glitches for time base settings of
500 us/div and slower. In this mode, the oscilloscope can sample more data than
it can store and display. So, when peak detect is turned on, the oscilloscope scans
through the extra data, picks up the minimum and maximum for each time bucket,
then stores the data in an array. Each time bucket contains two data sample.
The array is transmitted over the interface bus linearly, starting with time bucket 0
proceeding through time bucket n-1, where n is the number returned by the
:WAVeform:POINts? query (see
). In each time bucket, two values are
transmitted, first the minimum, followed by the maximum. The first pair of values
corresponds to the time bucket at the leftmost side of the screen. The last pair of
values corresponds to the time bucket at the far right side of the screen. In
:ACQuire:TYPE PEAK mode (see
), the value returned by the
:WAVeform:XINCrement query (see
) should be doubled to find the time
difference between the min-max pairs.
HRESolution Data
The high resolution (
smoothing
) mode is used to reduce noise at slower sweep
speeds where the digitizer samples faster than needed to fill memory for the
displayed time range.
Data Conversion
Word or byte data sent from the oscilloscope must be scaled for useful
interpretation. The values used to interpret the data are the X and Y references, X
and Y origins, and X and Y increments. These values are read from the waveform
preamble. Each channel has its own waveform preamble.
In converting a data value to a voltage value, the following formula is used:
voltage = [(data value - yreference) * yincrement] + yorigin
