The specification of power cord attached to the products is rated to
125VAC for all products which are designed to be used in theareas where commercial power supply voltage is not higher than
125VAC. Accordingly, you must change the power cord if you want
to use the product at the power supply voltage higher than 125VAC.
If you use the product without changing power cord to 250VAC
rated one, electric shock or fire may be caused.
When you used the product equipped with power supply voltage
switching system, please refer to the corresponding chapter in the
instruction manuals of each product.
● Power cord
(Important)

The attached power cord set can be used for thisdevice only.
If the attached power cord is damaged, stop using the product andcall us or your local dealer. If the power cord is used without thedamage being removed, an electric shock or fire may be caused.

● Protective fuse
If an input protective fuse is blown, the product does not operate. For a
product with external fuse holder, the fuse may be replaced. As for
how to replace the fuse, refer to the corresponding chapter in this
instruction manual.
If no fuse replacement procedures are indicated, the user is not
permitted to replace it. In such case, keep the case closed andconsult us or your local dealer. If the fuse is incorrectly replaced, afire may occur.

IIUSING THE PRODUCT SAFELY■ Warning item on Grounding
If the product has the GND terminal on the front or rear panel surface,
be sure to ground the product to safely use it.

■ Warnings on Installation environment● Operating temperature and humidity
Use the product within the operating temperature indicated in the“rating” temperature column. If the product is used with the vents ofthe product blocked or in high ambient temperatures, a fire may occur.
Use the product within the operating humidity indicated in the “rating”
humidity column. Watch out for condensation by a sharp humidity
change such as transfer to a room with a different humidity. Also, do
not operate the product with wet hands. Otherwise, an electric shockor fire may occur.
● Use in gas
Use in and around a place where an inflammable or explosive gas or
steam is generated or stored may result in an explosion and fire. Do
not operate the product in such an environment.
Also, use in and around a place where a corrosive gas is generated or
spreading causes a serious damage to the product. Do not operate
the product in such an environment.

USING THE PRODUCT SAFELY■ Warning Item for the Measurement● When you measure a part of a high voltage, be careful not to touch ahand to a measurement part directly. There is a risk of an electric shock.
● Be sure to connect the probe or the cable and the ground side of the input
connector to the ground potential (ground) of the substance measured.
Since the chassis of this instrument is connected to the ground of the
input block, connecting the earth lead of the probe to the potential
floating from the ground potential may result in the following: Electric shock A high current flows and damages the substance measured, this
instrument, and other connected device.
The following parts are connected to the chassis:
 Probe for each channel and ground side of the input BNC connector
 Grounding conductor of the accessory 3-core power cord
 Ground pin for an interface signal

3-2. Segmented Memory Acquisition (Option)
The advanced segmented memory utility allows the scope memory
to be divided into different segments. Each time the scope istriggered, it only acquires data for one segment of memory at a time.
This allows you to optimize the scope memory to only perform signal
acquisition during important signal events.
For example, for a signal with a number of pulses, normally theoscilloscope will acquire the signal until the acquisition memory of
the scope is filled up and then it will re-arm the trigger and thencapture again. This could result in a number of events not being
captured or captured at a less-than-desired resolution (dependingon the horizontal scale and sampling rate). However, the segmented
memory function would effectively allow you to capture more of the49

signal than you would otherwise. The diagrams below illustrate thispoint.
Normal acquisition mode example:
Normal memory acquisition period

Rearm time

Next trigger

Segmented memory acquisition example:
SegmentnSegment
n+1

Segment

Segment

As shown above, the memory is divided into segments to increase
the number of events that can be effectively captured with the sameacquisition memory. Also notice that the scope doesn’t need torearm the trigger between each segment, this makes the segmented
memory function especially useful for high speed signals. The time
between each segment is also recorded so that accurate signal
timing can also be measured.
The segmented memory function also supports automatic
measurements for each segment or statistics for all the captured
segments.

3-6-2-2. UART Serial Bus Configuration
The UART bus menu is designed to decode RS-232 and othercommon RS-232 variants such as RS-422, RS-485. The software
configuration is also flexible enough to decode the many proprietary
protocols based on RS-232.
Background
Basic RS-232 protocol uses single-ended datatransmissions. The signal voltage levels can behigh (±15V) and employ active low signaling.
High speed variants of RS-232, such as RS-422
and RS-485 use differential signaling andcommonly employ low voltage differential signals
with active high signaling.
Universal Asynchronous Receiver/Transmitter(UART) or RS-232 driver/receiver ICs commonlyused for embedded applications typically use
active high signaling with standard IC signal levels.
