Appendix 3 Common Questions
A8
To observe the voltage wave-
form on 600 V power lines
Use a voltage measuring input module and the Model
9322 Differential Probe or Model 9665 (10:1) or 9666
(100:1) attenuating probes.

Probe", "2.5 Connecting Atten-
uating Probes", and "3.10.15
Probe Attenuation Selection" in
the Input Module Guide
To perform frequency analy-
sis
Measure using the FFT function. We recommend using
an input module equipped with an anti-aliasing filter func-
tion (Models 8938, 8947, 8957 and 8960).
"Chapter 3 FFT Function" in the
Analysis Supplement
To record data without gaps,
or over a long term
Measure using the Real-Time
Saving function.
With the Memory and Recorder functions, data is saved
after each recording length, causing measurement to be
interrupted. With the Real-Time Saving function, data
can be stored continuously without gaps.

Real-Time Saving" in the In-
struction Manual

What is the basic setting pro-
cedure in order to view a
waveform?
To display a waveform, set the following: (1) timebase
(horizontal), (2) voltage axis range and zero position
(vertical), and (3) trigger [Off].
To use automatic setting for
measuring when the time-
base and the measurement
range are unknown
Press the FUNCTION MODE key to select the FN mode
on the Waveform screen (DISP key), and select F4
(Auto Setup).
The proper range is selected automatically, and record-
ing starts. Make other settings as occasion demands.
"3.3.5 Automatic Range Setting
(Auto-Ranging Function)" in the
Instruction Manual
To set up simply when the
measurement configuration is
already determined
Measurement configuration settings can be saved to
storage media as an auto-setup file (STARTUP.SET), so
the settings can be loaded automatically at power-on.
(Auto-Setup Function)
Also, the settings data can be save to the instrument
and it can be automatically loaded.

Settings File (Auto Setup Func-
tion)" in the Instruction Manual
What happens to measure-
ment configuration settings
when power is turned off?
When power is turned off, measurement configuration
settings are preserved within the instrument. When
power is turned back on, those measurement configura-
tion settings are recalled.
"3.6 Turning the Power On and
Off" (
⇒ p. 46) in this manual
What is the longest possible
recording length with the fast-
est timebase setting?
Recording time is determined by the [Shot]. The fastest
available timebase setting is [5 µs/div]. The recording
length can be increased by optional internal memory
expansion and by limiting which channels are used, so
the maximum time cannot be definitively specified.
A recording length of 10,000 divisions at 5 µs/div is
equivalent to 0.05 seconds recording time.
"4.2.4 Setting the Recording
Length (number of divisions)" in
the Instruction Manual
To observe phenomena such
as waveform anomalies prior
to a trigger event
From the Trigger Settings screen, enable Pre-Trigger
recording. (Set the position of the trigger point as a per-
centage of the recording length, where 0% represents
the recording start point and 100% represents the
recording end point)
"6.5 Pre-Trigger Settings" in the
Instruction Manual
If “Storage Off” appears
Verify that an input module is installed for the selected
channel.
If installed: On the Status Settings screen, verify that the
channel to be used for measurement is enabled [On].
If not installed: Select an installed module.
