Timing Chart Interval Descriptions
*1: There is an approximate error of 100

s in the delay time entered for Judgement Result EOM for the
setting value. t1 is the reference value for when the setting value is 0.0000 s.
*2: t2 is the reference value for when trigger input for during measurement is disabled.(p. 117), (p. 228)
*3: • When the panel number is read by the panel load function, the response time is as shown in the table
below.
• When the trigger synchronous output function and trigger delay is enabled, wait times are included.
*4: Reference value for Measurement frequency: 100 kHz, Measurement speed: FAST,
Measurement range: HOLD (p. 399)
*5: With the conditions shown in the table below, the time is added.
• Since the speed of the rise (LOW HIGH) of the comparator/BIN judgment result differs depending on the
configuration of the circuit connected to the EXT I/O, there is the likelihood of an incorrect judgment if the
level of the comparator/BIN judgment result acquired immediately after EOM output is used. To prevent this
from happening, a delay time (t1) between the comparator/BIN judgment result and the EOM can be set.
Furthermore, if the judgment result signal line of the EXT I/O is set to be reset simultaneously with the mea-
surement start signal, and a forced transition to the HIGH level is performed at the same time as TRIG, the
transition from LOW to HIGH does not occur when the judgment result is output after measurement ends.
As a result, the delay time between the judgment result and the EOM can be set to the minimum level. How-
ever, be careful because the judgment result confirmation interval is until the next trigger is accepted.
Furthermore, if the judgment result signal line of the EXT I/O is set to be reset simultaneously with the mea-
surement start signal, and a forced transition to the HIGH level is performed at the same time as TRIG, the
transition from LOW to HIGH does not occur when the judgment result is output after measurement ends.
As a result, the delay time between the judgement result output and EOM can be set to the minimum level.
As a result, the delay time between the judgement result output and EOM can be minimized. However, take
note that the evaluation result confirmation range is valid until the following triggers are accepted.
• During measurement, a trigger input from EXT /IO or communicating by interface may lead to a bigger dis-
persion of delay time between comparator or BIN judgement result output and EOM. As far as possible, try
not to control from external sources when carrying out measurement.
See "Setting the Delay Time from the Output of Comparator and BIN Judgment Results until Output of EOM (LOW) and
Resetting Judgment Results" (p. 115),(p. 226)
