This driver supports the newer RTO6 family scopes (and possibly others, untested).

\subsection{rs\_rtb2k}

A driver for RTB2000 and RTB2 oscilloscope.
Analog and digital channels are supported. An external trigger and a line trigger are available.
The function generator can be used with some restrictions.

Here is a list of notes on how to use it:
\begin{itemize}

\item The bit depth can be changed between 8 bits and 16 bits in the driver settings.

\item The selection lists with the sample rate and memory depth only work correctly with a fixed memory depth.

\item Entries in the selection list for the memory depth are rounded up, resulting in several identical entries.

\item When the oscilloscope is in Run mode and connected to ngscopeclient, data acquisition starts automatically.

\item When connecting the oscilloscope with line trigger to ngscopeclient, a trigger channel must be selected before changing the trigger. Otherwise, the program will crash.

\item The progress bar for downloading digital channels is only displayed for one channel.

\item If only the first logic probe is connected, only these 8 channels are displayed. The second logic probe is not recognized during operation.

\item The triggers for pattern and bus are missing.

\end{itemize}
