Press the
START
key and LED light.
When the pre-trigger is set, the trigger will not be registered for
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.
Data recording starts when trigger condition are met.
When trigger mode selected AUTO, instrument waits for about
1 second for trigger conditions to be met. After this interval,
data recording starts, regardless of trigger state.
Displays "Storing".
Waveform displays after data corresponding to recording length
have been stored in memory.
When the
STOP
key is pressed twice during measurement, the
8855 is forcibly stopped. (Waveform calculation are not
executed.)

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
8855 acquires measurement data in an amount corresponding to
the set recording length, and the measurement is stopped.
(Waveform display, Waveform calculation are executed.)
The maximum recording length allowing waveform processing calculation is
5000 divisions (20000 divisions for 128 M words, 80000 divisions for 512
M words).
