EVALUATION AND TEST

To evaluate and test the performance of the ADF4152HV, use
the following procedure:
1. If using a different VCO and loop filter than provided on
the board, ensure that a VCO and loop filter are properly
inserted on the board. If using a microwave VCO together
with the ADF5001 prescaler, move Jumper LK1 into
Position B to power up the prescaler. Use
generate the loop filter component values.
2. Install the Analog Devices
Connect the evaluation board to a PC using the supplied
USB cable. Follow the hardware driver installation procedure
when it appears.
3. If the on-board crystal oscillator is used, skip this step.
If an external reference is necessary, connect a reference
signal to the reference (REFIN) edge mount connector.
4. Connect the power supply to the board.
5. Connect a spectrum analyzer to Connector VCO_I/O.
6. Run the ADF4152 family software.
7. In the software window, set the RF frequency (Figure 6
shows a screenshot of the signal source analyzer operating
in phase noise mode, taken at a frequency of 1.4 GHz). Set
the PFD frequency as defined in ADIsimPLL, and program
the reference frequency to 25 MHz if the on-board TCXO
is used or to the frequency that has been supplied to the
REFIN connector. See Figure 7 for the suggested setup.
8. Measure the output spectrum. Figure 6 shows a
1.4 GHz output.
