Burst Complete When specified, the burst complete event (BCOMP event) produces a 1 µs
pulse following completion of a group of readings. The number of readings
in a group is specified by the NRDGS or SWEEP command. The BCOMP
event can be used to synchronize an external scanner to the multimeter when
making multiple readings per scanner channel. The following program is
similar to the preceding program except that it uses the BCOMP event and
makes 15 readings on each scanner channel. Connections for this example
are shown in Figure 21.
