|
Sample rates between 301000 Hz and 900000 Hz (inclusive) are not supported.
|
|
They cause an invalid configuration of the RTL chip.
|
|
rsamp_ratio = 28.8 MHz * 2**22 / sample_rate
|
|
If bit 27 and bit 28 of rsamp_ratio are different, the RTL chip malfunctions.
|
|
|
|
The RTL chip has a configurable 32-tap FIR filter.
|
|
RTL-SDR currently configures it for cutoff at 1.2 MHz (2.4 MS/s).

Casual test of ADC errors:
|
|
* DC offset in order of 1 code step
|
|
* I/Q gain mismatch in order of 4%
|
|
* I/Q phase mismatch in order of 1% of sample interval
