AFE7950: Programming and setup seems to work, not getting DAC output.

Part Number: AFE7950

Continuing from the previous post/question;

I have a programmable supply on both the AFE7950EVM, set at 5.5V (and it doesn't droop; at the test point even when drawing about 3 amps, it stays at 5.5V) and 12V going into the TSW14J57 board.

running through the tutorial ppt slides, I'm not getting any errors, and PLL2 Locked stays lit, but the TSW board D2 led only flashes during programming, and keeps flashing after running the S1 script. However, it goes out when i hit the "send" button in the DAC screen of the HSDC Pro software. I get no output from TXA on the AFE board, and the only connection I've made is from the SMA connector at TXA to a spectrum analyzer. I can measure frequency out to 7.5GHz and I'm not seeing anything.

I'm not getting any JESD errors and don't have to run the AFE.adcDacSync() command, though I've tried without and with running that.

D3 (PLL2 locked is on). The tutorial doesn't talk about it, but D4 on the AFEEVM (LMK locked) never comes on. not sure what thats for.

As I said, on the TSW board, after running S1 but *before* hitting the Send button in HSDC Pro, D2 is blinking, D3 is on and steady, D5 and D6 are on but dim?, D8 and D9 are on. The rest (D1, D4, D7) are off. On the AFE EVM board, *only* D3 (pll2 locked) is on.

As soon as I hit send (per the last post, I was told the tutorial was incorrect in stating that I should hit send before running the S1 script), on the TSW board, D1 (TX sync) flashes momentarily, and D2 turns off, and stays off. D3 remains on.

I get no signal on the TXA output. again, I have no other wires connected, on the coax from TXA to my spectrum analyzer.
