EVALUATION AND TEST

To evaluate and test the performance of the ADF4106, use the
following procedure:
1. Install the SDP-S software drivers. Connect the evaluation
board to a PC using the supplied USB cable. Follow the
hardware driver installation procedure that appears.
2. Connect the SDP-S connector to the EV-ADF4106SD1Z.
3. Connect a spectrum analyzer to Connector J2.
4. Run the Int-N software.
5. Select the SDP board and the
Device and Connection tab of the software front panel
window.
6. In the software window, set the VCO center frequency
(Figure 19 uses a 5800 MHz VCO). Set the PFD frequency
to 1000 kHz, and program the reference frequency to equal
that supplied to Connector J11 (or the TCXO). See Figure 20
for the suggested setup.
7. Measure the output spectrum. Figure 19 shows a 5800 MHz
output.
