Programming
5-12.
Triggering
a Measurement
5-13.
The calculator must trigger each measurement when the 5328A is programmed for single
measurement mode, "'SO". Two trigger methods are available. The program code "T" offers the
simplest way to trigger a measurement. However, the bus command Group Execute Trigger (GET)
may also be used. The counter responds more quickly to GET; also, GET can trigger the counter
simultaneously with other devices on the bus.
Using the progarm code "T"':

If the counter is programmed for multiple measurements, "S1', the counter will start each
measurement without a trigger command (see Figure 5-1). When the counter is also programmed
to wait to output, "S2", it will start
anew measurement as soon as the calculator reads the previous
one. In the continuous cycle mode, ''S3", the counter does not wait to output, but starts a new
measurement. This mode is useful for the user to visually monitor a series of readings.
