/* DIGITIZE - Used to acquire the waveform data for transfer over
* the interface. Sending this command causes an acquisition to
* take place with the resulting data being placed in the buffer.
*/
/* NOTE! The use of the DIGITIZE command is highly recommended
* as it will ensure that sufficient data is available for
* measurement. Keep in mind when the oscilloscope is running,
* communication with the computer interrupts data acquisition.
* Setting up the oscilloscope over the bus causes the data
* buffers to be cleared and internal hardware to be reconfigured.
* If a measurement is immediately requested there may not have
* been enough time for the data acquisition process to collect
* data and the results may not be accurate. An error value of
* 9.9E+37 may be returned over the bus in this situation.

* ------------------------------------------------------------------
* In this example we will do the following:
* - Save the system setup to a file for restoration at a later time.
* - Save the oscilloscope display to a file which can be printed.
* - Make single channel measurements.
