Mask Test Commands 24
Agilent Infiniium 9000 Series Oscilloscopes Programmer's Reference 443
:MTESt:AMASk:SOURce
Command :MTESt:AMASk:SOURce {CHANnel<N> | COMMonmode<P> | DIFFerential<P>
| WMEMory<N> | FUNCtion<F> | CLOCk | EQUalized
| MTRend | MSPectrum}
The :MTESt:AMASk:SOURce command selects the source for the
interpretation of the AMASk:XDELta and AMASk:YDELta parameters when
AMASk:UNITs is set to CURRent. When UNITs are CURRent, the XDELta
and YDELta parameters are defined in terms of the channel units, as set
by the :CHANnel:UNITs command, of the selected source. Suppose that
UNITs are CURRent and that you set SOURce to CHANNEL1, which is
using units of volts. Then you can define AMASk:XDELta in terms of volts
and AMASk:YDELta in terms of seconds.
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> An integer, 1-4.
<P> An integer, 1-2.
<F> An integer, 1-16.
Example This example sets the automask source to Channel 1.
myScope.WriteString ":MTEST:AMASK:SOURCE CHANNEL1"
Query :MTESt:AMASk:SOURce?
The :MTESt:AMASk:SOURce? query returns the currently set source.
Returned Format
[:MTESt:AMASk:SOURce] {CHANnel<N> | COMMonmode<P> | DIFFerential<P>
| WMEMory<N> | FUNCtion<F> | CLOCk | EQUalized
| MTRend | MSPectrum}<NL>
Example This example gets the source setting for automask and prints the result on
the computer display.
