QUICK TEST PROCEDURE

To use the ADAR1000-EVALZ to test and evaluate the
ADAR1000, take the following steps:
1. Plug the SDP adapter into the P5 connector on the
ADAR1000-EVALZ.
2. Connect the 3.3 V and −5 V power supplies to the
corresponding banana jacks on the ADAR1000-EVALZ.
3. Use a USB cable to connect the SDP adapter to the PC that
has the ADAR1000-EVALZ evaluation software downloaded.
4. Connect one port of the network analyzer to the RF_IO
connector and another port to the RX1 input connector.
5. Use the Start menu to run the ADAR1000-EVALZ
evaluation software (see the Evaluation Board Software
Installation section for more information), as shown in
Figure 24.
Figure 24. Run Control Software from the Start Menu
6. After the ADAR1000-EVALZ evaluation software starts up,
click the Connection tab and then click Connect (see
Figure 27).
7. Ensure that SDP board connected appears on the status bar.
8. For receive mode operation, click the Manual Register
Write tab (see Figure 21) and click Choose Input File to
choose the RX1_MaxG_45.txt file for the register values.
Note that this file (and the similar settings files) does not
change any of the GUI settings. The file only writes data to
the ADAR1000.
9. Click Write All to send the register values to the ADAR1000.
Receive Channel 1 is now turned on at full gain.
10. Measure the gain and return loss on the network analyzer. A
typical response is shown in Figure 25.
