Figure 4-6 Using an external scanner
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
