4.7 Start and Stop Operation (FFT)
See Section 4.3, "STATUS Settings (FFT)", Quick Start Chapter
6, "Input Channel Settings", Quick Start Chapter 7, "Trigger
Functions".
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".
When the printer is enabled, the recording waveform is printed
at the same time it is displayed.
When the
STOP
key is pressed twice during measurement, the
8855 is forcibly stopped.
The FFT calculation result display, auto-print, and automatic
storage is not performed.
After capturing measured data, the FFT analysis is carried out
and then the result is displayed.
Auto printout and auto save are executed.
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
8855 acquires measurement data in an amount corresponding to
the set recording length, and the FFT analysis is carried, and
then the measurement is stopped. (FFT analysis result, auto
printout, auto save are executed.)
When the
STOP
key is pressed twice, the measurement is
stopped forcibly. (FFT analysis result, auto printout, auto save
are not executed.)
