The software was No-OS, and I created the original board.
I saw the attached image, but the Q_DATA side level of Rx Framer is abnormally small.
(The top of the image is I and the bottom is Q.)
I am confirming that the RF input is correct data.
Do you know what the cause is?
IQ_SIGNAL2.png is the waveform when it gets out normally once every several hundred times.
From initCalMask, trackingCalMask of headless.c
When commenting out RX_QEC, normal waveform is output.
uint32_t initCalMask =
// LOOPBACK_RX_LO_DELAY |
// LOOPBACK_RX_RX_QEC_INIT |
// TX_LO_LEAKAGE_INTERNAL |
// TX_QEC_INIT |
// RX_LO_DELAY |
uint32_t trackingCalMask =
// TRACK_RX1_QEC |
// TRACK_TX1_LOL |
// TRACK_TX1_QEC |
// TRACK_ORX1_QEC |
