Defines the demodulator sampling rate, the number of samples that are sent to the host \
computer per second. A rate of about 7-10 higher as compared to the filter bandwidth \
usually provides sufficient aliasing suppression. This is also the rate of data \
received by LabOne Data Server and saved to the computer hard disk. This setting has \
no impact on the sample rate on the auxiliary outputs connectors. Note: the value \
inserted by the user may be approximated to the nearest value supported by the \
instrument.
