Hello ,

 

Our customer is evaluating of QDUC mode of AD9957.

Thogh I could run on QDUC mode with parallel input using AD9957/PCB, but I can not run BFI mode.

 

Q1.

I generated serial data file using MVG and the MVG output 2 files, the one is I data and another is Q data .

I tried to load the I/Q data to FIFO using "FIFO Control", but the "FIFO Control" indicate an error "The file you are trying to load is to large!".

How many bits of data  I can set for BFI on AD9957/PCB ?

Attached figure is the MVG settings to gen. 16QAM data.

 

Q2.

MVG output 2 files, the one is I data and another is Q data.

But the "FIFO Control" panel can load only one file at onece.

How do I load the I-data and Q-data files ?

 

 

Best regards,

ysuzuki
