Description of Normal Situations:
[1] The current in analog mode is above 6A under 45W power supply and above 1A under 5W. However,
in digital mode, the current will be reduced by 50%.
[2] The APC voltage should be above 2V at TP811.
[3] Check whether there is an appropriate TX LO signal at TP803.
[4] Check whether the gain is 16dB and the input signal is 0dBm at Q801.
[5] Check whether the gain is 15dB and the input signal is 0dBm at Q805.
[6] Check whether the gain is 11dB and the input signal is 0dBm at Q804.
[7] Check whether the gain is 10dB and the input signal is 0dBm at Q802 and Q803.
