Channel Commands 12
Agilent Infiniium 90000 Series Oscilloscopes Programmer's Reference 183
:CHANnel<N>:ISIM:APPLy
Command :CHANnel<N>:ISIM:APPLy "<transfer_funct_file>"
The :CHANnel<N>:ISIM:APPLy command applies a pre- computed transfer
function to the waveform. If InfiniiSim is in 2 port mode, the file must be
a .tf2 file. If in 4 port mode, the file must be a .tf4 file. Use the
ISIM:STATe command to enable InfiniiSim before issuing the APPLy
command.
<N> An integer, 1 - 4.
<transfer_funct_f
ile>
The full path to the .tf2 file name (if in 2 port mode) or the .tf4 file (if in
4 port mode).
Example This example applies the example.tf4 file to the waveform on channel 1.
myScope.WriteString _
":CHANNEL1:ISIM:APPLy"+_
"""C:\Users\Public\Documents\Infiniium\Filters\example.tf4"""
Query :CHANnel<N>:ISIM:APPLy?
The :CHANnel<N>:ISIM:APPLy? query returns the currently selected
function file name when 2 port or 4 port mode is enabled.
Returned Format
[CHANnel<N>:ISIM:APPLy] <file_name><NL>
Example This example puts the current transfer function file name in the variable
strFile. The program then prints the contents of the variable to the
computer's screen.
myScope.WriteString ":SYSTEM:HEADER OFF"
myScope.WriteString ":CHANNEL1:ISIM:APPLy?"
strFile = myScope.ReadString
Debug.Print strFile
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
