An \f[C]rx\ stop\f[] followed by an \f[C]rx\ start\f[] will result in
the samples file being truncated.
If this is not desired, be sure to run \f[C]rx\ config\f[] to set
another file before restarting the rx stream.
.IP \[bu] 2
For higher sample rates, it is advised that the \f[C]bin\f[]ary output
format be used, and the output file be written to RAM (e.g.
\f[C]/tmp\f[], \f[C]/dev/shm\f[]), if space allows.
For larger captures at higher sample rates, consider using an SSD
instead of a HDD.

Synchronizing transmitters and receivers on a single chain will cause an
offset of 11 samples between TX and RX; these samples should be
discarded.
This is caused by different processing pipeline lengths of TX and RX.
This value might change if the FPGA code is updated in the future.

Running \f[C]tx\f[] without any additional commands is valid shorthand
for \f[C]tx\ config\f[].

The \f[C]wait\f[] command takes an optional \f[C]timeout\f[] parameter.
This parameter defaults to units of milliseconds (\f[C]ms\f[]).
The timeout unit may be specified using the \f[C]ms\f[] or \f[C]s\f[]
suffixes.
If this parameter is not provided, the command will wait until the
transmission completes or \f[C]Ctrl\-C\f[] is pressed.

Configuration parameters take the form \f[C]param=value\f[], and may be
specified in a single or multiple \f[C]tx\ config\f[] invocations.

The \f[C]n\f[], \f[C]samples\f[], \f[C]buffers\f[], and \f[C]xfers\f[]
parameters support the suffixes \f[C]K\f[], \f[C]M\f[], and \f[C]G\f[],
which are multiples of 1024.
.IP \[bu] 2
For higher sample rates, it is advised that the input file be stored in
RAM (e.g.
\f[C]/tmp\f[], \f[C]/dev/shm\f[]) or on an SSD, rather than a HDD.
.IP \[bu] 2
When providing CSV data, this command will first convert it to a binary
format, stored in a file in the current working directory.
During this process, out\-of\-range values will be clamped.
.IP \[bu] 2
When using a binary format, the user is responsible for ensuring that
the provided data values are within the allowed range.
This prerequisite alleviates the need for this program to perform range
checks in time\-sensitive callbacks.
