Hi AD Data Converter Engineers,
I am having an issue very similar to the one reported by Beverly on Oct 4, 2016. She asked:
"How do I resolve FMC_12V Overcurrent state using the ADS7-V2 with a AD9164-FMCB-EBZ installed?"
to which Biao. H replied, on 13 October 2016:
"1. Try to upgrade the FPGA firmware to the latest version.
2. NCO test mode should work with external 12V power supply."
I was able to upgrade the ADS7-V2 firmware, but this did not resolve the problem. I am able to work with my DAC evaluation board (AD9162-FMCC-EBZ) in external/ standalone NCO test mode, using the ACE program. Unfortunately, I need to evaluate the AD9162 with a special waveform (signal vector), thus requiring the use of the ADS7-V2 and the DPG program.
When I connect the AD9162-FMCC-EBZ to the ADS7-V2 board (moving the 12 VDC power from the DAC to the FPGA board), ACE does NOT recognize the DAC. When I use the DPG software, the program sees both the AD9162-FMCC-EBZ and the ADS7-V2... but throws up the (red) FMC_12V overcurrent LED on the ADS7-V2. No LEDs light up on the AD9162-FMCC-EBZ. When I check the 12V test point on the AD9162-FMCC-EBZ board, I read ~ 1 volt. Needless to say, I cannot load a signal vector, or get the AD9162-FMCC-EBZ to work with ACE (when it is connected to the ADS7-V2 board).
Please advise on how to resolve this issue, I need to evaluate the AD9162 with our preferred test signals ASAP.
