EVALUATION AND TEST
To evaluate and test the performance of the ADF5356 , use the
following procedure:
1. Install the ADF5356 software (see the PLL Software
Installation Guide ).
2. Follow the hardware driver installation procedure
(Windows XP only).
3. Connect a 50 Ω terminator to the RFOUTA− SMA
connector.
4. Connect the EV-ADF5356SD1Z 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 ADF5356 software.

Seq.
10. Connect the spectrum analyzer to the SMA
connector. See Figure 4 for a typical evaluation setup.
11. Measure the output spectrum and single sideband phase
noise.
Figure 6 shows a phase noise plot of the SMA
with the VCO frequency equal to 6.6 GHz.
