The correct choice depends on the way the hardware is connected, the most common form uses the setting `Direct Sampling (Q branch)`. There is a few caveats concerning this modification: * Bypassing the tuner also bypasses all available gain stages on the chip, so the "Device gain" setting will not have any effect in direct sampling mode.
