4.8 Start and Stop Operation (MEM)
See Section 4.3, "STATUS Settings",
Chapter 9, "Input Channel Settings",
Chapter 10, "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, unit waits for about 1
second for trigger conditions to be met. After this interval, data
recording starts, regardless of trigger state.
Displays "Storing".
When roll mode is set to ON, the waveform is displayed
(scrolling) immediately at the start of recording
Using the
VIEW
key to display the time (from measurement
started time).
When the
STOP
key is pressed twice during measurement, the
8841/42 is forcibly stopped. Then the waveform data until the
STOP
key is pressed is displayed and saved. When the auto
saving is set to ON, the data until a forced termination is
automatically saved. (Auto printout is not executed.)
Waveform displays after data corresponding to recording length
have been stored in memory.
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
8841/42 acquires measurement data in an amount corresponding
to the set recording length, and the measurement is stopped.
(Waveform display, auto printout, and auto save are executed.)
When the time axis range is set to the slow range (not more
than 10 ms/DIV), the waveforms measured until the
STOP
key is
pressed are displayed.
When the time axis range is set to the fast range (greater than
10 ms/DIV), waveforms are not displayed. (Waveforms are
displayed only if measured data having recording length equal
to the previous setting exist.)
