Waveform Commands 34
Agilent Infiniium 9000 Series Oscilloscopes Programmer's Reference 1129
:WAVeform:TYPE?
Query :WAVeform:TYPE?
The :WAVeform:TYPE? query returns the current acquisition data type for
the currently selected source. The type returned describes how the
waveform was acquired. The waveform type may be:
• RAW — data consists of one data point in each time bucket with no
interpolation.
• AVERage — data consists of the average of the first n hits in a time
bucket, where n is the value in the count portion of the preamble. Time
buckets that have fewer than n hits return the average of the data they
contain. If the :ACQuire:COMPlete parameter is set to 100%, then each
time bucket must contain the number of data hits specified with the
:ACQuire:AVERage:COUNt command.
• VHIStogram — data is a vertical histogram. Histograms are transferred
using the LONGLONG format. They can be generated using the
Histogram subsystem commands.
• HHIStogram — data is a horizontal histogram. Histograms are
transferred using the LONGLONG format. They can be generated using
the Histogram subsystem commands.
• INTerpolate — In the INTerpolate acquisition type, the last data point in
each time bucket is stored, and additional data points between the
acquired data points are filled by interpolation.
• DIGITAL — data consists of digital pod or bus values for each time
bucket.
• PDETect — data consists of two data points in each time bucket: the
minimum values and the maximum values.

Example This example places the current acquisition data type in the string
variable, strType, then prints the contents of the variable to the
computer's screen.
Dim strType As String ' Dimension variable.
myScope.WriteString ":WAVeform:TYPE?"
strType = myScope.ReadString
Debug.Print strType
