Commands by Subsystem 3

'because this is greater than the maximum sample rate by 5 times,

'only 400 points (or 1/5 the points) can be gathered on a single

'trigger. 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 have not 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.
