EVALUATION AND TEST
To evaluate and test the performance of the ADF4113HV, use
the following procedure:
1. Install the Int-N PLL software.
2. Connect the SDP-S connector to the EV-ADF4113HVSD1Z
and to a PC using the supplied USB cable. If you are using
Windows XP, follow the hardware driver installation pro-
cedure that appears.
3. Connect a spectrum analyzer to Connector J2.
4. Run the Int-N PLL software.
5. Select the SDP board and the ADF4113HV device in the
Select Device and Connection tab in the main window of
the evaluation board software.
6. From the Main Controls tab in the main window of the
evaluation board software, set the desired frequency in the
RF VCO Output Frequency text box. Set the PFD Frequency
text box to 1000 kHz, and program the Reference Frequency
text box to 25 MHz. See Figure 20 for the suggested measure-
ment setup.
7. Measure the output spectrum. Figure 19 shows a phase
noise plot at 1360 MHz output frequency.
