Installing Hardware Components
Both instruments and DUTs can be inserted in the same IQS-500 expansion
unit (in specific areas). You may find useful to insert only instruments that
do not require a warmup period in an expansion unit that also houses
DUTs. This way, turning off the expansion unit to insert your DUTs, will not
affect the instruments warmup. For more information on how to define the
area reserved to instruments, see Configuring Areas Specific for
Instruments on page 19.
To avoid multiple warmup periods, you can consult the list of required
instruments for the test you want to perform.
The application will show you the required connections, step by step,
during the test.
