:WAVeform Commands
Example Code
' WAVEFORM_DATA - To obtain waveform data, you must specify the
' WAVEFORM parameters for the waveform data prior to sending the
' ":WAVEFORM:DATA?" query.
Once these parameters have been sent,
' the waveform data and the preamble can be read.
'
' WAVE_SOURCE - Selects the channel to be used as the source for
' the waveform commands.
myScope.WriteString ":WAVEFORM:SOURCE CHAN1"
' WAVE_POINTS - Specifies the number of points to be transferred
' using the ":WAVEFORM:DATA?" query.
myScope.WriteString ":WAVEFORM:POINTS 1000"
' WAVE_FORMAT - Sets the data transmission mode for the waveform
' data output.
This command controls whether data is formatted in
' a word or byte format when sent from the oscilloscope.
Dim lngVSteps As Long
Dim intBytesPerData As Integer
' Data in range 0 to 65535.
myScope.WriteString ":WAVEFORM:FORMAT WORD"
lngVSteps = 65536
intBytesPerData = 2
' Data in range 0 to 255.
'myScope.WriteString ":WAVEFORM:FORMAT BYTE"
'lngVSteps = 256
'intBytesPerData = 1
' GET_PREAMBLE - The preamble block contains all of the current
' WAVEFORM settings.
It is returned in the form <preamble_block><NL>
' where <preamble_block> is:
'
FORMAT
: int16 - 0 = BYTE, 1 = WORD, 4 = ASCII.
'
TYPE
: int16 - 0 = NORMAL, 1 = PEAK DETECT, 2 = AVERAGE
'
POINTS
: int32 - number of data points transferred.
'
COUNT
: int32 - 1 and is always 1.
'
XINCREMENT
: float64 - time difference between data points.
'
XORIGIN
: float64 - always the first data point in memory.
'
XREFERENCE
: int32 - specifies the data point associated with
'
x-origin.
'
YINCREMENT
: float32 - voltage diff between data points.
'
YORIGIN
: float32 - value is the voltage at center screen.
'
YREFERENCE
: int32 - specifies the data point where y-origin
'
occurs.
