Marker Commands 23
Agilent Infiniium 9000 Series Oscilloscopes Programmer's Reference 429
:MARKer:X1Y1source
Command :MARKer:X1Y1source {CHANnel<N> | COMMonmode<P> | DIFFerential<P>
| FUNCtion<F> | WMEMory<N> | CLOCk | MTRend | MSPectrum | EQUalized
| HISTogram | 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.
The COMMonmode and DIFFerential sources are just aliases that can be
used in place of the channel names to apply to differential or common
mode signals. These are just aliases - no state change occurs if you refer
to a differential channel and you are not in differential mode.
DIFFerential1 refers to the differential signal between channels 1 and 3
(and COMMonmode1 refers to the common mode channel between these
same channels). DIFFerential2 refers to the differential signal between
channels 2 and 4 (and COMMonmode2 refers to the common mode
channel between these same channels).
<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.
<P> An integer, 1-2.
<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.
