4.2 Details of Measurement Setting
This section explains various setting for "
Configure
" tab.
Set the speed for inputting and storing the waveform of the input signal.
Time axis range setting expresses the time for 1 division.
The sampling period is 1/100th of the set value for the time axis range.
(100 samples/DIV)
Selecting external sampling will synchronize sampling with the external
signal. (1 kHz or less)
Setting Procedure
1. Press the
DISPLAY
key to select the
"
Configure
" tag. Press the
ENTER
key
to display the menu.
2
.
Move the cursor to "
Time/DIV
", and
press the
ENTER
key.
3. Use the
CURSOR
key to select a value,
then press the
ENTER
key to set the
time axis value.
The currently selected time axis value is shown in red.
If the time axis is set to 20ms or less (a faster range), the waveform will not appear until the set
data recording length has been loaded.
If the time axis is set to 50ms or more (a slower range), the waveform up to 10DIV will be
displayed and measurement continued. When the averaging process is enabled, the waveform will
not appear until the entire set data recording length has been loaded.
The 8730-10, 8731-10 accepts up to 1kHz signals for external sampling. The number of samples
per DIV is 100. For details, see 8.4.3.
When using external sampling, note that the pre-trigger is fixed to 0%. This setting cannot be
edited. For pre-trigger details, see 4.4.3.
