Safety Requirement

General Safety Summary

Please review the following safety precautions carefully before putting the instrument

into operation so as to avoid any personal injuries or damages to the instrument and

any product connected to it. To prevent potential hazards, please use the instrument

only specified by this manual.

Use Proper Power Cord.

Only the power cord designed for the instrument and authorized by local country

could be used.

Ground The Instrument.

The instrument is grounded through the Protective Earth lead of the power cord. To

avoid electric shock, it is essential to connect the earth terminal of power cord to the

Protective Earth terminal before any inputs or outputs.

Connect the Probe Correctly.

Do not connect the ground lead to high voltage since it has the isobaric electric

potential as ground.

Observe All Terminal Ratings.

To avoid fire or shock hazard, observe all ratings and markers on the instrument and

check your manual for more information about ratings before connecting.

Use Proper Overvoltage Protection.

Make sure that no overvoltage (such as that caused by a thunderstorm) can reach the

product, or else the operator might expose to danger of electrical shock.

Do Not Operate Without Covers.

Do not operate the instrument with covers or panels removed.

Use Proper Fuse.

Please use the specified fuses.

Avoid Circuit or Wire Exposure.

Do not touch exposed junctions and components when the unit is powered.

Do Not Operate With Suspected Failures.

If you suspect damage occurs to the instrument, have it inspected by qualified service

personnel before further operations. Any maintenance, adjustment or replacement

especially to circuits or accessories must be performed by RIGOL authorized

personnel.

III

Keep Well Ventilation.

Inadequate ventilation may cause increasing of temperature or damages to the device.

So please keep well ventilated and inspect the intake and fan regularly.

Do Not Operate in Wet Conditions.

In order to avoid short circuiting to the interior of the device or electric shock, please

do not operate in a humid environment.

Do Not Operate in an Explosive Atmosphere.

In order to avoid damages to the device or personal injuries, it is important to operate

the device away from an explosive atmosphere.

Keep Product Surfaces Clean and Dry.

To avoid the influence of dust and/or moisture in air, please keep the surface of device

clean and dry.

Electrostatic Prevention.

Operate in an electrostatic discharge protective area environment to avoid damages

induced by static discharges. Always ground both the internal and external conductors

of the cable to release static before connecting.

Handling Safety

Please handle with care during transportation to avoid damages to buttons, knob

interfaces and other parts on the panels.

DS2000 Series Overview

DS2000 is a high-performance and low bandwidth digital oscilloscope developed on

the basis of the Ultra Vision technique. DS2000, featuring rather deep memory depth,

ultra-wide dynamic range, superb waveform capture rate and all-round trigger

functions as well as hardware waveform record function and good display effect, is an

invaluable debug instrument in various fields (such as communication, cosmonautics,

national defense, embedded system, computer, research and education) and is the

one with the most complete functions and most outstanding specification among the

digital oscilloscopes with lower than 200 MHz bandwidth.

Main features:

200 MHz, 100 MHz and 70 MHz bandwidth.

Ultra Vision technique.

2 GSa/s maximum real-time sample rate.

50,000 wfms/s (dots display) waveform capture rate.

Real-time hardware waveform recording, waveform playback, record open

(constant on) and waveform analysis functions. Up to 65,000 frames of waveform

can be recorded.

56 Mpts maximum memory depth (option) and 14 Mpts standard memory depth.

256 degree gray scale display.

Low noise, 500 μV/div to 10 V/div ultra-wide vertical dynamic range.

8.0 inches, WVGA (800*480) 160,000 color TFT LCD, with ultra-wide screen, vivid

picture, low power consumption and long service life.

Adjustable brightness of analog channel waveform.

Auto setting of waveform display (AUTO).

16 kinds of trigger functions including multiple protocol triggers.

Standard parallel decoding and multiple serial decoding options.

Auto measurements of 24 waveform parameters and measurement functions

with statistic.

Precise delayed sweep function.

Built-in FFT function.

Pass/Fail test function.

Multiple waveform math operation functions.

Standard configuration interfaces: USB Device, USB Host, LAN and GPIB

(optional).

Support USB storage device and PictBrige printer.

Conform to LXI-C instrument standards. Enable quick, economic and efficient

creation and reconfiguration of test system.

Support remote command control.

Embedded help enables easier information access.

Support multiple languages and Chinese/English input.

Novel and delicate industrial design and easier operation.
