EVALUATION AND TEST
To evaluate and test the performance of the ADF5355, use the
following procedure:
1. Install the ADF5355 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. Connect the EV-ADF5355SD1Z board to the SDP-S board.
5. Connect the 6 V power supply to the banana connectors
and power up the board using S1 (check that LED1 is on).
6. Connect the USB cable from the SDP-S board to the PC.
7. Run the ADF5355 software.
8. Select ADF5355 and SDP board (black) in the Select
Device and Connection tab of the software front panel
display window (see Figure 2).
9. Click the Main Controls tab, and set the VCOout (MHz)
to a frequency of 6800 MHz and then click Write All
Registers.
10. Connect the spectrum analyzer to SMA Connector
RFOUTA+. See Figure 4 for a typical evaluation setup.
11. Measure the output spectrum and single sideband phase
noise.
