After the calibration of all channels is completed, save your work to
a
mas Project File. Otherwise turn back to step
the calibration for the remaing multiplexer channels.
Please note: Loading and saving TTC/12TC calibrations via the internal load & save
function of the wizard is not possible for multi-channel calibrations. It is recom-
mended to save the calibration as standard
11.3 De-Embedding of the Multiplexer
As the calibration of the multiplexer unit according to section
labor-intensive, the de-embedding functionality (see chapter 7) can be used
as an alternative to minimize the errors caused by the multiplexer.
The advantage is, that only the TDR system needs to be calibrated while
the multiplexer influence is de-embedded. The basic requirement for this is
the availability of the S-parameters for all signal paths of the multiplexer. In
this scenario the calibration takes place in the plane CH1 / CH2 right before
the multiplexer (see Fig. 14). The work flow to de-embed the multiplexer is
described below.
