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.
