No. The only thing that effects the sample rate is the decimation or
interpolation rate.

The bandwidth across the USB is multiplied by the number of channels
enabled. The sample rate within a single channel is set by the
interpolation or decimation rate.

On receive the complex sample rate is:
u.converter_rate()/u.decim_rate()
On transmit the complex sample rate is:
u.converter_rate()/u.interp_rate()
