Buffered mode
is a means of acquiring a limited contiguous set of data at high rate, so as to
preserve the full time resolution. Up to 65535 readings of thirty-two channels each can be
buffered in the F3200E and sent up to the host computer as a series of blocks of data. The data
display on the host computer will inevitably lag behind the actual measurements because the
communications channels cannot keep up with the acquisition rate, but all the data is captured
and can be saved and analyzed at your convenience.
The maximum measurement rate is determined by the requested number of readings and the rate
at which the internal buffers can be unloaded to the host computer. Typical values are greater
than 50 kHz for 10000 readings and greater than 160 kHz for 1000 readings if the F3200E is
connected via Ethernet.
