Emulate / De-embed
Emulate / De-embed Overview
Touch the Emulate / De-embed button on the Eye Doctor II dialog to access the Emulate / De-embed
dialog.
The Emulate / De-embed block allows you to De-embed Fixtures, De-embed Serial Data Channels, and
Emulate Serial Data Channels.
l
Fixture De-embedding - Use Fixture De-embedding to move the reference for your measurement
to a point before the fixture (such as directly to the transmitter output) by removing the effects of
the fixture. A Touchstone Format S-Parameter file describing your fixture is required to de-embed.
l
Channel Emulation / De-embedding - Use Channel Emulation / De-Embedding to move the ref-
erence for your measurement to a different point in your system. You can either move the ref-
erence to a point after a serial data channel by emulating the channel effects, or to a point before
a serial data channel by de-embedding the channel (similar to Fixture De-embedding). For both
emulation and de-embedding of serial data channels, a Touchstone Format S-Parameter file
describing your channel is required.
Emulate / De-embed Within SDAIII-CompleteLinQ
When accessed through SDAIII-CompleteLinQ, the Emulate / De-embed dialog will look like this:
If you also have the Virtual Probe package, the EyeDr or VP selector appears at the bottom of the dialog.
This allows you to choose whether to use the EyeDr. user interface or the Virtual Probe user interface to
configure de-embedding and emulation.
You can configure emulation and de-embedding on up-to-four lanes independently when using SDAIII-
CompleteLinQ.
