Agilent Infiniium 90000 Series Oscilloscopes Programmer's Reference 423
:MARKer:X1Y1source
Command
:MARKer:X1Y1source {CHANnel<N> | FUNCtion<F> | WMEMory<N> | CLOCk
| MTRend | MSPectrum | EQUalized | DIGital<M> | BUS<N>}
The :MARKer:X1Y1source command sets the source for the Ax and Ay
markers. The channel you specify must be enabled for markers to be
displayed. If the channel, function, or waveform memory that you specify
is not on, an error message is issued and the query will return channel 1.
MTRend and MSPectrum sources are only available if the oscilloscope has
the EZJIT option installed and the feature is enabled.
The CLOCk source is only available if the oscilloscope has the High Speed
Serial option installed and the feature is enabled.
The EQUalized source is only available if the oscilloscope has the High
Speed Serial option and the Serial Data Equalization option installed and
the features are enabled. This command uses the Feed- Forward Equalized
(FFE) signal as the source.
<N> CHANnel<N> is an integer, 1- 4.
BUS<N> is an integer, 1- 4. Buses are available on mixed- signal
oscilloscopes.
WMEMory<N> is an integer, 1- 4.
<F> FUNCtion<F> is an integer, 1- 16.
<M>
An integer, 0- 15. Digital channels are available on mixed- signal
oscilloscopes.
Example
This example selects channel 1 as the source for markers Ax and Ay.
myScope.WriteString ":MARKer:X1Y1source CHANnel1"
Query
:MARKer:X1Y1source?
The :MARKer:X1Y1source? query returns the current source for markers
Ax and Ay.
Returned Format
[:MARKer:X1Y1source] {CHANnel<N> | FUNCtion<F> | WMEMory<N> | CLOCk
| MTRend | MSPectrum | EQUalized | DIGital<M> | BUS<N>}<NL>
Example This example returns the current source selection for the Ax and Ay
markers to the string variable, strSelection, then prints the contents of the
variable to the computer's screen.
Dim strSelection As String ' Dimension variable.
myScope.WriteString ":MARKer:X1Y1source?"
strSelection = myScope.ReadString
Debug.Print strSelection
