Does ADI offer digital pre-distortion guidance/platform for high-speed DACs used in a trasnmit chain?
ADI offers a complete eval platform for evalualting DPD: Called the AD-MSDPD-EVB, it takes baseband I and Q data and generates an RF output signal up to +18dBm which can be passed to an external PA for transmit. Spectral purity is targeted up to MCGSM class 1 levels of performance when coupled with a suitable digital Predistortion algorithm.
The parts used in this TX path of this platform are the AD9122 DAC and ADL5375 I/Q modulator. More details can be found in the attached datasheet.
We are trying to configure MSDPD board .
We have installed SPI controller,MSDPD Softwares properly.
The system is detecting USB.
We are following the instructions of MSDPD_Gen1_Users_Guide_RevPrC.pdf, and setup is as there in the Pdf.
When we are opening MSDPD software, automatically it is invoking SPI controller but is giving an error "No Usb devices found. USB cable possibly Disconnected".
When we are trying to Program MSDPD , it is showing the error as "no connection could be made because target machine actively refused it 127.0.0.1:55000" .
Please find the attached images.
We have properly connected the USB connector with PC and MSDPD board and Power Source is also connected and it is on.
Please help us in fixing this issue.
