Lesson 4 – Defining the Signal Routing
217
For details of the routing tasks, see the manual “Test Setup”,
Chapter “Using the Routing Setup Tool”.
For the DAC routing, you will need two routing sets. One for the
DAC Linearity test and the other for the DAC Distortion test. The
routing tasks Connect, Loop-back, Disconnect, and Flush will be
used.
Routing set 1 is the set to be used for the DAC Linearity test with
the High Resolution Digitizer (WDB). As the analog output signal
of the DAC is only wired to the WDA, you need to set up a loop-
back via the input multiplexer of the WDA, and via a DUT board
line to an input pin of the WDB.
