Why IQ is swapped when framer input loopback to deframer output by setting 0x667c[D4]=1?
SG output 735MHz CW, inject to 9025 RX(RX LO is 733MHz),BB get +2MHz CW.
setting 0x667c[D4]=1.
I see 9025 TX output is 786MHz CW(TX LO is 788MHz), DAC input is -2MHz CW?
Is it that IQ is swapped when framer input loopback to deframer output by setting 0x667c[D4]=1?
How can i do that IQ is not swapped when framer input loopback to deframer output?
please help me
Please let me out.
Thanks in advance.
