We followed the steps indicated in the Quick Start Guide of AD9122.
Power Supply: P5 (+5V), P6 (GND)
Signal Source: J1 (CLKIN), Set source to 500MHz, 2dBm output
PC USB Cable: XP2
Spectrum Analyzer: J3 (DAC1_P) or J8 (DAC2_P)
DPG2: P1 and P2
The only difference with this one is we used DPG3. We also did a 29 MHz single tone signal and followed the exact steps in the Quick Start Guide but we could not get the output from it. Have we missed out something in the setup? We are resorting in debugging the board and double checking it with the schematics. I hope someone can give us insights to go about this.
