9-6 Triggering
Measure action
The measure action block of the trigger model is where a measurement is performed. How-
ever, if the repeating filter is enabled (see Figure 9-3), the instrument samples the specified num-
ber of reading conversions to yield single filtered reading. Only one reading conversion is
performed if the digital filter is disabled, or after the specified number of reading conversions
for a moving average filter is reached.
Output triggers
Model 6514 can send out an output trigger (via the rear panel TRIGGER LINK connector)
right after the measure action and/or when operation leaves the trigger layer. An output trigger
can be used to trigger another instrument to perform an operation (e.g., select the next output
step for a source).
