ADF4355-2
, use the
following procedure:
1.
Install the
ADF4355-2
software (see the
PLL Software
Installation Guide
).
2.
Follow the hardware driver installation procedure
(Windows XP only).
3.
Connect a 50 Ω terminator to RFOUTA−.
4.

board to the
SDP-S
board.
5.
Connect the 6 V power supply to the banana connectors
and power-on the board using S1 (check that LED1 is on).
