Waveform Commands
:WAVeform:COUPling?
Query
:WAVeform:COUPling?
The :WAVeform:COUPling? query returns the input coupling of the
currently selected source and always returns DC. This query is provided
for compatibility to other Infiniium oscilloscopes.
Returned Format
[:WAVeform:COUPling] DC<NL>
Example
This example places the current input coupling of the selected waveform
in the string variable, strSetting, then prints the contents of the variable.
Dim strSetting As String ' Dimension variable.
myScope.WriteString ":WAVEFORM:COUPLING?"
strSetting = myScope.ReadString
Debug.Print strSetting
See Also
The :CHANnel<N>:INPut command sets the coupling for a particular
channel.
You can use the :WAVeform:SOURce command to set the source for the
coupling query.
Source Return Value
CGRade Coupling of the lowest numbered channel that is on.
HISTogram The coupling of the selected channel. For functions, the coupling of the
lowest numbered channel in the function.
CHANnel The coupling of the channel number
FUNCtion The coupling of the lowest numbered channel in the function
WMEMory The coupling value of the source that was loaded into the waveform
memory. If channel 1 was loaded, it would be the channel 1 coupling
value.
