11-10 Status Structure Model 2700 Multimeter/Switch System User’s Manual
Serial poll programming example
This example is written specifically for the KPCI-488.2 GPIB card and QuickBasic/
VisualBasic with the appropriate IEEE libraries. Other types of cards and/or languages
may have different function calls that are equivalent to the initialize(), transmit(), send(),
srq, and spoll() calls used below.
SRQ when buffer fills with 500, 1000, 1500, and 1750 readings
The following program will store 2000 readings in the buffer. When the buffer fills with
500 readings (quarter full), an SRQ will occur and a message will be displayed on the
computer to indicate that event. An SRQ and message will also occur when the 1000th
(half full), 1500th (three-quarter full), 1750th (buffer notify), and 2000th (full) reading is
stored.
