USING THE PRODUCT SAFELY

WARNING

CAUTION

■ Do not remove the product’s covers and panels

Never remove the product’s covers and panels for any purpose. Otherwise, the user’s electric shock or fire may be incurred.

■ Warning on using the product

Warning items given below are to avoid danger to user’s body and life and

avoid the damage or deterioration of the product. Use the product, observing the following warning and caution items.

■ Warning items on power supply

● Power supply voltage

The rated power supply voltages of the product are 100, 120, 220 and 240VAC. The rated power supply voltage for each product should be confirmed by reading the label attached on the back of the product or by the “rated” column shown in this instruction manual. The specification of power cord attached to the products is rated to 125VAC for all products which are designed to be used in the areas 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 this

device only.

If the attached power cord is damaged, stop using the product and call us or your local dealer. If the power cord is used without the damage 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 and consult us or your local dealer. If the fuse is incorrectly replaced, a fire may occur.

III

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 of

the 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 shock or 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.

● Installation place Avoid installing the product on inclined places or on places subject to vibration. Otherwise, the product may slip or fall down to cause damages or injury accidents.

■ Do not let foreign matter in

Do not insert metal and inflammable materials into the product from its vent and spill water on it. Otherwise, electric shock or fire may occur.

■ Warning item on abnormality while in use

In abnormal situations, such as “smoke”, “fire”, “abnormal smell” or “irregular noise” occur from the product while in use, stop using the

product, turn off the switch, and remove the power cord plug from the outlet. After confirming that no other devices catch fire, ask us or your local dealer.

USING THE PRODUCT SAFELY

■ 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”

At connecting as Bad Example, +90V and chassis are shorted, and damages substance a measured. Therefore do not make such connection. If the instrument is not grounded, a potential of the chassis is +90V. Ground a chassis, in order to prevent an electric shock accident.

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.

4-1-4. Set the Sampling Mode

Background

The DCS-9700 has two types of sampling modes: ET (Equivalent Time) and Sin(x)/x interpolation. Equivalent time sampling is able to achieve a sample rate of 100GSa/s when sampling periodic waveforms. Sin(x)/x interpolation uses a sinc interpolation formula to reconstruct a continuous signal between sampled points.

Sin(x)/x

One sample of data is used to reconstruct a single waveform. Sin(x)/x sampling should be used when the time base is relatively slow or if single shot events need to be captured.

Equivalenttime sampling

Sampled data is accumulated a number of times to reconstruct a single waveform. This increases the sampling rate, but can only be used for repetitive signals. This mode is usually used when the time base is too fast for real-time sampling.

Panel Operation

1. Press the Acquire key.

Acquire

2. Press the ET/sin(x)/x key on the bottom menu to toggle between equivalent time sampling (ET) and sin(x)/x interpolation.

The sampling rate will be shown on the bottom right-hand corner.

4-1-5. Set the Record Length

Background

The number of samples that can be stored is set by the record length. Record length is important in an oscilloscope as it allows longer waveforms to be recorded and/or allows higher sampling rates to be achieved when equivalent time sampling is used. There are two record length settings, Auto and Short. The Auto setting will set the record length to maximum record length available, dependent on the scope settings. The Short setting will set the record length to 1k. The maximum record length for the DCS-9700 depends on the number of active channels, which channels are active, and whether the normal or single shot triggering mode is used. The table below describes the record lengths that are available for each triggering mode.

4-2. Segmented Memory Acquisition

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 use the full potential of the scope one segment at a time. This effectively allows you to capture intermittent signal events while ignoring signal inactivity. The Advanced Segment Memory Utility is applicable for both analog and digital channels.
