quantities (S-parameters, wave quantities, ratios etc.) and other trace settings are avail-
able.
The following example shows the reflected wave a

, the transmitted wave b
2
, and the
forward transmission coefficient S
21
of a DUT with the settings of the previous sections.
Fig. 3-7: Example for pulse profile measurement
It can be seen that the steepness of the edges of the S
21
pulse arises from ratioing (b/a)
and does not provide a measure for the rise and fall times of the pulse itself.
3.9 Possible Extensions
The extension unit R&S ZVAX24 can accommodate up to three pulse modulators (for
two source paths and a receiver path) plus a variety of other hardware options. Options
installed internally are shown in the "ZVAX Path Configuration" dialog (
figure 3-3 ). An
arbitrary combination of options may be used simultaneously.
For an overview of R&S ZVAX24 options and their use refer to chapter 4, "Overview of
R&S ZVAX24 Options" , on page 29.
