9.3 Pre-Measurement Settings
244
If the timebase of the whole waveform is
set extremely slow (such as 1 hour/div)
and the timebase of the measurement
waveform is set fast (such as 100
s/div),
a whole measurement cannot be recorded
if the recording (time) is set too short.
Be especially careful when manually set-
ting the timebase for the whole waveform.

Setting a Recording Length
CURSOR
Move the cursor to the
[Shot]
item.
F1 to F8
(Switch Display: F8)
Select the setting method for recording length.
When selecting [Fixed] or [User]
CURSOR
Move the cursor to the
[Fixed]
or
[User]
item.
F1 to F8
(Switch Display: F8)
Select the length of waveform to be acquired (re-
cording length).
When selecting [Time]
CURSOR
Move the cursor to the
[Day]
(or Hour, Minute,
Second) item.
F1 to F8
(Switch Display: F8)
Select the amount for recording waveforms.

Set the timebase for the whole waveform
CURSOR
Move the cursor to the
[Auto]
or
[Manual]
item.
F1 to F8
Select whether the timebase should be automat-
ically set to suit measurement waveform settings.
When selecting [Manual]
CURSOR
Move the cursor to the
[Timebase]
item.
F1 to F8
Set the time per division (timebase) of the hori-
zontal axis.
When selecting [Auto]
The timebase for the whole waveform is set according to the time-
base and recording length settings of the measurement waveform,
and the amount of space available on the storage media. The mini-
mum amount of space required on the save destination storage me-
dia is as follows. Measurement with the [Auto] setting is disabled if
insufficient storage space is available. In this case, choose [Manual]
and set the timebase for the whole waveform manually.
• Model 8860-50 (9715-50) with 32 MW internal memory: at least
32 MB available space
• Model 8861-50 (9715-50) with 64 MW internal memory: at least
64 MB available space
• Models 8860-50 and 8861-50 other than the above: at least 128
MB available space
Fixed
(Fixed recording length)
Select from the fixed recording lengths(de-
fault setting)
User
(Arbitrary)
Set an arbitrary recording length in units of
divisions
Time
Specify the amount of time to record.
10, 20, 50, 100, 200, 500 ms/div
1, 2, 5, 10, 30, 50, 100 s/div
1, 2, 5, 10, 30 min/div
1 h/div
Shot: When [Time] is selected
The displayed recording time and maxi-
mum recording length are linked to the set
recording length.
Recording length may be limited by the
available space at the save destination,
the number of channels used, and the
timebase of the whole waveform (when
manually set).
To set the maximum recording length
for the available space at the save des-
tination
Click the [Set Maximum] button to set the
recording length to suit available storage
space.
