Agilent InfiniiVision 6000 Series Oscilloscopes Programmer's Guide 163
' less than or equal to the maximum sample rate, the full 1000 points
' will be digitized in a single acquisition. Now, use 1 us/div
' (10 us across the screen). 1000 divided by 10 us equals 100 MSa/s;
' 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.
