3.4 Powering STRATA Units
The method you use to power the transmitter can vary depending on the
following:
• The transmitter configuration, whether you’re using a single TCU, a TXU and
HPU, or a TCU, TXU, and HPU as an integrated system.
• Whether the TCU and TXU are to be co-located or physically separated over
some distance.
Once you understand which configuration you’re using, refer to
Table 3-2, "Power
Requirements," on page 3-3
.
