TSW14J56EVM: TSW14J56EVM, DAC37J82EVM Programming

BobL

Part Number: TSW14J56EVM

Comrades, I program the TSW14J56EVM and the DAC37J82EVM appropriately and generate a 375MHz tone. The tone outputs for a couple of minutes then stops. The TX CLK LED on the TSW stops flashes, so data is no longer being sent to the DAC. Is this normal or should the FPGA board continuously send the data?

BobL,

Make sure both boards are sourced from a power supply capable of providing at least 4A each.

Regards,

Jim

I think it was a power supply issue, so I swapped out the supply for a 5A. Now I get an "Error 1097 occurred at Call Library Function Node in TSW1400.iv lib:14J56revD_Firmware Details.vi->TSW1400.iv lib:Frame.vi" when trying to select the DAC board in the Pro software. Ideas? I tried rebooting the PC without success.

Was still a supply issue! Used two seperate power supplies and things seem to be working now! Thx!
