:WAVeform:YORigin?
Query
:WAVeform:YORigin?
The :WAVeform:YORigin? query returns the y- origin voltage value for the
currently specified source. The voltage value returned is the voltage value
represented by the waveform data digital code 00000.
• For BYTE and WORD data, and voltage waveforms, it is the voltage at
digital code zero.
• For ASCii data format, the YORigin is the Y- axis value at the center of
the data range. Data range is returned in the Y increment.
Returned Format
[:WAVeform:YORigin] <real_value><NL>
<real_value>
A real number in exponential format.
Example This example places the current Y- origin value in the numeric variable,
varCenter, then prints the contents of the variable to the computer's
screen.
myScope.WriteString ":SYSTEM:HEADER OFF" ' Response headers off.
myScope.WriteString ":WAVEFORM:YORIGIN?"
varCenter = myScope.ReadNumber
Debug.Print FormatNumber(varCenter, 0)

For more information on BYTE and WORD formats, see "Understanding
WORD and BYTE Formats" on page 956.
You can obtain the Y- origin value through the :WAVeform:PREamble?
query.
N O T E
A "Waveform data is not valid" error occurs when there is no data available for a channel.
When this occurs, a zero value is returned.
