These issues both concern `read_data_one_channel`, which is why I summarize them both in one issue entry. For setting the data width, the command `WFMO:BYTE_NR 2` is sent to the scope....
On my system, the reply to ```SEL:%s?'%(self.channel_name(channel))``` in the method is_channel_selected is not '1' for an active channel, but '1\n'. Therefore, is_channel_selected, that compares this value to '1', always returns...
When connected via USB, supported oscilloscopes could easily be detected based on their USB device identifier. This would simplify the application of the package in interactive usage scenarios.
The time axis now goes to either the value of `DATa:STOP` or the record length, depending on which of the two is lower. Fixes #21
The construction of the time axis in PyTektronixScope is implemented as `self.x_0 + np.arange(self.data_start-1, self.data_stop)*self.delta_x`. This approach is correct in principle - `x0` is the result of `WFMO:XZE?` (time coordinate...
