ADAR1000 EVALZ General Questions

did I understand it right?.....there are two possibilities to set the phase or gain.

1. I am using the GUI and follow the steps up on page 8

2. If I want to save some time, I can use the manual register and upload the txt files for gain settings

maybe you can tell me the values for I and Q for aiming a phase of 60,90,180 degrees....because it didn´t work with my values

sorry, that I am spaming you...I followed all the steps in the datasheet and connecter the Networkanalyzer to the RF IO and TX1... there is only a noise seeable....no signal of the phase with 45 degrees....Can you help me?

• You will need to generate custom files for your desired phase(s). Please see Tables 13, 14, 15, and 16 in the datasheet for I & Q vector values for various phases. 
• The GUI provides more than one way to set gain and phase.  One way is to use the TX Registers or RX Registers tab.  Another way is to use the Manual Register Write tab to directly write to Registers 0x10 through 0x27
• You will not be able to discern any phase if you just see noise on the VNA
• To make sure you have a good part and board and your setup is OK, refer to the sections labeled "CONTROL USING THE MANUAL REGISTER WRITE" and "QUICK TEST PROCEDURE" in the user guide and use the Tx1 max gain setting file.  Make sure the supply current on the +3.3V supply rail is approximately 350 mA. 

thank you very much....actually I have a power supply with +3.3V and -5V... you can have a look at the

picture. I also have uploaded the file for manual register write....but there is always just noise seeable. Of course I have referred to the sections you have mentioned...
