How long will recording con-
tinue when the recording
length is set to [Cont] with the
Recorder function?
When trigger criteria are met, recording starts and con-
tinues until you press the STOP key. Up to 5,000 divi-
sions of data (with Model 9715 Memory Board installed)
from measurements prior to the stopping of recording is
retained in internal memory.
When Auto Print or Auto Save is enabled, the data ac-
quired by the instrument is printed or saved on each such
occasion.
About memory capacity and re-
cording length:
"4.2.4 Setting the Recording
Length (number of divisions)";

(Cont)" in the Instruction Manual
What is the difference
between the Memory and
Recorder functions?
Which function is selected determines how the timebase
is set. The sampling method for each function is also dif-
ferent.
Because the purpose of the Memory function is acquisi-
tion of instantaneous waveforms, if you set a slow time-
base for long-term recording, the sampling period may
be unsatisfactorily lengthened. On the other hand, the
Recorder function samples and records maximum and
minimum values at the specified sampling rate regard-
less of the timebase setting. As a result, however, only
slow timebase settings are available.

If channel waveforms are
overlapping and hard to see
Channel waveforms can be displayed separately by
shifting the zero position of each waveform, or by sepa-
rating the waveform traces on the Sheet Settings
screen.

The grid lines (graticule)
causes waveforms to be hard
to see,
or you want to display the grid
To remove the grid, set the [Grid Type] on the Environ-
ment Settings screen of the System screen to [Off].
The grid is displayed when [Dotted Line] or [Solid Line]
is selected.
(Default setting: [Dotted Line])

Waveform traces are too thick
Waveform traces appear thick when noise is present on
the signal. Enable the low-pass filter to suppress the
noise.

Settings" in the Input Module
Guide
Logic waveforms are not dis-
played
On the [Logic] page of the Sheet Settings and Channel
Settings screens, set the channels to be displayed to
[On].
If “Storage Off” is displayed:
Set the logic channel to [On] on the [Use Ch] page of the
Status Settings screen.

A waveform is continuously
acquired even when trigger
criteria have been set
Is the Trigger Mode set to [Auto]? (Continuously
acquires waveforms)
Select [Single] to record only once when trigger criteria
are satisfied, or select [Repeat] to record repeatedly.

Cursor values and waveforms
are overlapped and hard to
see
Press the DISP key to display waveforms and numerical
values separately.
