3.11 BUS DATA TRANSMISSION TIMES
A primary consideration is the length of time it takes to
obtain a reading once the instrument is triggered to make
a conversion. The length of time will vary somewhat de-
pending on the selected function and trigger mode. Table
3-15 gives typical times.
3.12 SCANNER PROGRAMMING
