NOTE
5.6 Testing Using EXT I/O
With the test conditions for testing by the comparator having been set (with
the trigger setting set to external trigger), when in this state a trigger signal
is input via the EXT I/O connector, or when on the screen the soft
key is pressed, then the decision result is output on the comparator result
output signal line of the EXT I/O connector.
When a panel number has been selected using the panel load signal at the
input of a trigger signal via the EXT I/O connector, the 3532-50 loads the
measurement conditions for the panel number and then begins measurement.
An example of testing timing is as follows:
You can use a communication command (:IO:RESult:RESet) to select whether
the judgment results for comparator measurement are reset when the start-of-
measurement signal is input or updated when measurement ends.
Note1: Reset at the same time as TRIG
