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.
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.
Change The Power Fuse.
If the power fuse needs to be changed, please return the instrument back to our
factory and the RIGOL authorized operator will change it for you.
Do Not Operate Without Covers.
Do not operate the instrument with covers or panels removed.
Avoid Circuit or Wire Exposure.
Do not touch exposed junctions and components when the unit is powered.

III
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.
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.

The power softkey is used to turn the generator on or off. When the power
softkey is turned off, the generator is in standby mode and the generator is in
power-off mode only when the power cable at the rear panel is pulled out.
Users can enable or disable the function of this softkey. When enabled, users
need to press this softkey to start the instrument after power-on; when
disabled, the instrument starts automatically after power-on.

sweep or burst output manually (only when Output1 is enabled).
Trigger2: in sweep or burst mode, it is used to trigger CH2 to generate a
sweep or burst output manually (only when Output2 is enabled).
Output1: enable or disable the output of CH1.
Output2: enable or disable the output of CH2.
CH1 CH2: execute channel copy (refer to the introductions in Channel
Copy).
10. Counter
Press Counter to turn the counter on or off. When the counter is turned on,
the backlight of the key is illuminated and the left indicator flickers. If the
counter interface is currently displayed, press this key again to disable counter
function; if the screen currently displays interfaces other than the counter
interface, press this key again to switch to counter interface (refer to the
introductions in Counter).
11. Numeric Keyboard
It is used to input parameters and consists of numbers (0 to 9), decimal point
(.), operators (+/-) and buttons (“Enter”, “Cancel” and “Del”). If a negative is
required, please input an operator “-” before the numbers. In addition, the
decimal point “.” can be used to switch units quickly and the operators “+/-”
can be used to switch between uppercase and lowercase (for the use method
of the numeric keyboard, refer to the introduction in Parameter Setting
Method).
12. Knob
During parameter setting, it is used to increase (clockwise) or decrease
(counterclockwise) the current highlighted number.
It is used to select file storage location or select the file to be recalled when
storing or recalling file.
It is used to switch the character in the soft keyboard when entering filename.
It is used to select built-in waveform when defining the shortcut waveform of
User.

13. Direction Keys
When using the knob and direction keys to set parameters, the direction keys
are used to switch the digits of the number.
During filename input, they are used to move the cursor.
14. Waveforms
Sine----Sine
Generate a Sine waveform with frequency from 1μHz to 160MHz.

th
order of harmonic.
Users can set the harmonic “Order”, “Type”, “Ampl” and “Phase”.
User----User-defined Waveform Key
Users can define the built-in waveform frequently used as shortcut (Utility
UserKey). And then, in any operation interface, press User to quickly open
the desired waveform and set its parameters.
15. Modes
Mod----Modulation
Generate the modulated waveforms. Provide various analog modulation and
digital modulation modes and can generate AM, FM, PM, ASK, FSK, PSK, BPSK,
QPSK, 3FSK, 4FSK, OSK or PWM modulated signal.
