11.2 Timing Chart
372
In analyzer mode, if a trigger signal is input from the EXT I/O or is pressed in the screen, the
judgment results are output from the signal line for comparator result output of the EXT I/O.
Furthermore, if the panel number is selected with the panel load signal when a trigger signal is input from the
EXT I/O, the measurement condition of that panel number is loaded and then measurement is performed.
The following provides an example of measurement timing when the trigger setting is or .
(In the timing examples, the valid edge of the TRIG signal is set to falling (ON).)
• If the trigger setting is set to STEP, INDEX and EOM transition to LOW every time the measurement for
each point ends, and then transition to HIGH when there is trigger input.
ERR also transitions to LOW each time measurement completes if a measurement error occurs.
• Whether the judgment results of comparator measurement are reset at the time of the measurement
start signal or updated at the point in time when measurement ends can be selected on the instrument
or by a communication command.

Resetting Judgment Results" (p. 226)

Signal line Description
INDEX The transition to HIGH is performed when measurement of the first sweep point starts after trigger signal input
and the transition to LOW is performed when the analog measurement of the last sweep point ends.
(The HIGH level is maintained during sweep measurement.)
EOM The transition to HIGH is performed when measurement of the first sweep point starts after trigger signal input.
Measurement of the last sweep point ends and the transition to LOW is performed after judgment result output.
(The HIGH level is maintained during sweep measurement.)
