■ Warning Item for the Measurement

● When you measure a part of a high voltage, be careful not to touch a

hand 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

“Bad example” Prohibition

When measuring the floating potential, a differential method of measurement is recommended ( refer to the figure below ).

“Good example”

USING THE PRODUCT SAFELY

■ Input / Output terminals Maximum input to terminal is specified to prevent the product from being damaged. Do not supply input, exceeding the specifications that are indicated in the "Rating" column in the instruction manual of the product. Also, do not supply power to the output terminals from the outside. Otherwise, a product failure is caused.

■ Calibration Although the performance and specifications of the product are

checked under strict quality control during shipment from the factory, they may be deviated more or less by deterioration of parts due to their aging or others. It is recommended to periodically calibrate the product so that it is used with its performance and specifications stable. For consultation about the product calibration, ask us or your local dealer.

■ Daily Maintenance

When you clean off the dirt of the product covers, panels, and

knobs, avoid solvents such as thinner and benzene. Otherwise, the paint may peel off or resin surface may be affected. To wipe off the covers, panels, and knobs, use a soft cloth with neutral detergent in it. During cleaning, be careful that water, detergent, or other foreign matters do not get into the product. If a liquid or metal gets into the product, an electric shock and fire are caused. During cleaning, remove the power cord plug from the outlet.

Use the product correctly and safely, observing the above warning and caution items. Because the instruction manual indicates caution items even in individual items, observe those caution items to correctly use the product.

If you have questions or comments about the instruction manual, ask us or E-Mail us.

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 is triggered, 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 the oscilloscope will acquire the signal until the acquisition memory of the scope is filled up and then it will re-arm the trigger and then capture again. This could result in a number of events not being captured or captured at a less-than-desired resolution (depending on the horizontal scale and sampling rate). However, the segmented memory function would effectively allow you to capture more of the

Normal memory acquisition period Rearm time Next trigger

signal than you would otherwise. The diagrams below illustrate this point. Normal acquisition mode example:

Segmented memory acquisition example:

As shown above, the memory is divided into segments to increase the number of events that can be effectively captured with the same

acquisition memory. Also notice that the scope doesn’t need to

rearm 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.

Progress Indicator

Progress Indicator Indicates the number of segments that have to

Background

Basic RS-232 protocol uses single-ended data transmissions. The signal voltage levels can be high (±15V) and employ active low signaling. High speed variants of RS-232, such as RS-422 and RS-485 use differential signaling and commonly employ low voltage differential signals with active high signaling.

Universal Asynchronous Receiver/Transmitter (UART) or RS-232 driver/receiver ICs commonly used for embedded applications typically use active high signaling with standard IC signal levels.
