16.1 Waveform Parameter Calculation
────────────────────────────────────────────────────
・Data recording starts when trigger condition are met.
・When trigger mode selected AUTO, unit waits for about 1
second for trigger conditions to be met. After this interval, data
recording starts, regardless of trigger state.
・Press the START key and LED light.
・When the pre-trigger is set, the trigger will not be registered fo
r
a certain period after the start of measurement. (During this
interval,
Pre-trigger standby is shown on the display.)
・When the trigger can be registered, the indication
Waiting for
trigger is shown on the display.
Meeting the trigger condition
Storing measurement data
・Displays "Storing".
Waveform displays after data corresponding to recording leng
th
have been stored in memory.
・When the STOP key is pressed twice during measurement, th
e
8826 is forcibly stopped. (Parameter calculation are not
executed.)
・Result to printer ：ON →Prints the evaluation results.
・Result save ：ON →Saves the evaluation results.
・Auto print ：ON →Prints the measurement data.

・Displays "Calculating".
・Depending on the results of the waveform parameter
calculation, a GO (pass) or NG (fail) result is returned.
【 When the evaluation result is GO 】
・Outputs GO signal.
【 When the evaluation result is NG 】
・Outputs NG signal.
・The calculation value for that channel is marked with an "

"
(on the display and the printout).
Measurement is repeated until the stop conditions are met.
（When COMP setting: ON）

・End of measurement.
・Each time when trigger conditions are met, data are recorded
and memory contents are overwritten.
【 End of measurement in REPEAT and AUTO trigger modes
】
・When the STOP key is pressed once during measurement, the
8826 acquires measurement data in an amount corresponding
to the set recording length, and the measurement is stopped.
