ACPM-7891 PA Control Board
We have designed the
ACPM-7891 PA control board to
interface with the LTC1758
However, the ACPM-7891 PA
Control Board can also be tested
without using the LTC1758 demo
board. Test Setup II, Figure 7,
demo board to simplify engineer- illustrates the equipment setup
ing efforts. Test Setup I, Figure 6, under that scenario.
illustrates the equipment setup if
the LTC1758 demo board is to be
used with the ACPM-7891 PA
Control Board.
