Channel Commands 12
Agilent Infiniium 9000 Series Oscilloscopes Programmer's Reference 205
:CHANnel<N>:ISIM:CORRection
Command :CHANnel<N>:ISIM:CORRection <percent>
The :CHANnel<N>:ISIM:CORRection command sets the amount of linearly
scaled correction applied to the non- DC frequency components of the
measured signal. This lets you trade off the amount of correction to apply
via the transformation function versus the increase in noise it may create
at higher frequencies. In other words, you can fine- tune the amount of
high- frequency noise versus the sharpness of the step response edge.
<N> An integer, 1-4.
<percent> If you are making averaged mode measurements or applying a transfer
function that does not magnify the noise, use the full correction by setting
this field to 100%.
However, if you are working with eye diagrams or making jitter
measurements and the transfer function is magnifying the noise, you may
want to limit the correction by selecting a lower percentage.
Example This example sets the channel 1 InfiniiSim correction factor to 80%.
myScope.WriteString ":CHANnel1:ISIM:CORRection 80"
Query :CHANnel<N>:ISIM:CORRection?
The :CHANnel<N>:ISIM:CORRection? query returns the selected input
channel's percent correction factor.
Returned Format
[CHANnel<N>:ISIM:CORRection] <percent><NL>
Example This example gets the current channel 1 InfiniiSim correction percentage
and places it in the numeric variable, varIsimCorrection. The program then
prints the contents of the variable to the computer's screen.
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
