24 Mask Test Commands
:MTESt:SOURce
Command :MTESt:SOURce {CHANnel<N> | COMMonmode<P> | DIFFerential<P>
| FUNCtion<F> | EQUalized}
The :MTESt:SOURce command selects the channel which is configured by
the commands contained in a mask file when it is loaded.
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 selects channel 1 as the mask test source.
myScope.WriteString ":MTEST:SOURCE CHANNEL1"
Query :MTESt:SOURce?
The :MTESt:SOURce? query returns the channel which is configured by the
commands contained in the current mask file.
Returned Format
[:MTESt:SOURce] {CHANnel<N> | FUNCtion<F> | EQUalized}<NL>
Example This example gets the mask test source setting and prints the result on the
computer display.
Dim strAmask_source As String
myScope.WriteString ":MTEST:SOURCE?"
strAmask_source = myScope.ReadString
Debug.Print strAmask_source
