Channel Commands 12
Agilent Infiniium 90000 Series Oscilloscopes Programmer's Reference 191
:CHANnel<N>:ISIM:PEXTraction
Command :CHANnel<N>:ISIM:PEXTraction {P12 | P32 | P34 | P14 | DIFFerential
| COMMonmode}
The :CHANnel<N>:ISIM:PEXTraction command selects the InfiniiSim port
extraction. The selections are:
• P12 — Use ports 1 - > 2, only valid for channels 1 and 2.
• P32 — Use ports 3 - > 2, only valid for channels 1 and 2.
• P34 — Use ports 3 - > 4, only valid for channels 3 and 4.
• P14 — Use ports 1 - > 4, only valid for channels 3 and 4.
• DIFFerential — valid for all channels.
• COMMonmode — valid for all channels.
<N> An integer, 1 - 4.
Example This example selects the channel 1 InfiniiSim differential port extraction.
myScope.WriteString ":CHANNEL1:ISIM:PEXTraction DIFFerential"
Query :CHANnel<N>:ISIM:PEXTraction?
The :CHANnel<N>:ISIM:PEXTraction? query returns the current InfiniiSim
port extraction selection.
Returned Format
[CHANnel<N>:ISIM:PEXTraction] {P12 | P32 | P34 | P14 | DIFF | COMM}<NL>
Example This example puts the current InfiniiSim port extraction selection for
channel 1 in the string variable, strMode. The program then prints the
contents of the variable to the computer's screen.
myScope.WriteString ":SYSTem:HEADer OFF"
myScope.WriteString ":CHANNEL1:ISIM:PEXTraction?"
NOTE
This CHANnel command only applies if you have purchased the InfiniiSim software
application.
NOTE
You can specify differential and/or common mode channels using the following convention.
If you have differential or common mode channels enabled (using either the
:CHANnel<N>:DIFFerential or :CHANnel<N>:COMMonmode commands) then:
•
:CHANnel1 would refer to the Channel 1 - Channel 3 differential channel
• :CHANnel2 would refer to the Channel 2 - Channel 4 differential channel
• :CHANnel3 would refer to the Channel 1 + Channel 3 common mode channel
• :CHANnel4 would refer to the Channel 2 + Channel 4 common mode channel
