Other Parts Discussed in Thread: DAC38RF82, TSW14J57EVM
Hi everyone,
My intended application is to generate two synchronized waveforms through the DAC38RF82EVM 's two channels.To do this I load a 100kHz sine wave to channel 1 and a square wave with 50% duty cycle to channel 2 in HSDC Pro.Below are the two waveforms in csv form and my HSDC Pro and DAC GUI configuration screenshots.
The DAC38RF82 I use works in dual dac mode with real inputs LMF=821 while using the onboard VCXO (CMODE4). I started with an example cfg file from another post,
7181.6144MSPS_8x_10M_ref_LMF_841.cfg
then changed the configurations in the DAC GUI quick start page, and follow the instructions in that thread of loading another cfg file using the low level tab instead of clicking on the "Reset DAC and JESD Core & SYSREF Trigger".
But the output results are really weird.The square wave did not turn up as expected and the two channels were not phase aligned.
I haven't used any DAC evaluation boards before, so I'm not sure what's wrong.
I will appreciate any help,thanks!
