Waveform Commands 32
Agilent Infiniium 90000 Series Oscilloscopes Programmer's Reference 901
: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, INTerpolate,
AVERage, HHIStogram, PDETect, or VHISTogram.
RAW RAW data consists of one data point in each time bucket with no
interpolation.
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.
AVERage 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.
HHIStogram The data is a horizontal histogram. Histograms are transferred using the
LONGLONG format. They can be generated using the Histogram subsystem
commands.
PDETect PDETect data consists of two data points in each time bucket: the
minimum values and the maximum values.
VHIStogram The data is a vertical histogram. Histograms are transferred using the
LONGLONG format. They can be generated using the Histogram subsystem
commands.
Returned Format
[:WAVeform:TYPE] {RAW | INTerpolate | AVERage |
HHIStogram | PDETect | VHIStogram}<NL>
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
