Safety Requirement
General Safety Summary
Please review the f ollowin g 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 for use within the
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.
If a probe is used, do not connect the ground lead to high volt age 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 o vervolt age (such as that caused by a thunde rstorm) 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.
Do Not Insert Anything into the Holes of Fan.
Do not insert anything into the holes of the fan to avoid damaging the instrument.

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 i nspected by qualified service
personnel before further operations. Any maintenan ce, adjustment or replacement
especially to circuits or accessories must be performed by RIGOL authorized
personnel.
Keep Well Ventilation.
Inadequate ventilation ma y cause increasing of temperat ure or da mages to t he 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 elect ric shock, please
do not operate in a humid environment.
Do Not Operate in an Explosive Atmosphere.
In order to a void damages to the device or personal i njuries, it is imp ortant to operat e
the device away fr om an exp losive a tmosphere.
Keep Product Surfaces Clean and Dry.
To avoid the infl uence of dust and /or moisture in air, please keep the su rface of device
clean and dry.
Electrostatic Prevention.
Operate in an electrostatic discharge protective area environment to avoid damages
induced by static dischar ges. Alwa ys ground both th e internal an d external con ductors
of the cable to release static before connecting.
Proper Use of Battery.
If a battery is supplied, it must not be e xpose d to high temperature or in cont act with
fire. Keep it out of the reach of children. Improper change of battery (note: lithium
battery) may cause explosion. Use RIGOL specified battery only.

1. Cycle Period
Press this softkey and use the numeric ke yboard or knob to set the cycle perio d of
the new waveform. The set ting r ange is from 20 ns to 1 Ms. Note that the time of
the last point that can be defined should be less than the cycle period.
2. High VLimit
Press this softke y and use the numeric key board or k nob to set the hi gher level of
the new waveform. The upper limit of this level is +5 V (50 Ω), and the lower limit
is the minimum which is greater than current setting of the “Low VLimit”.
3. Low VLimit
Press this softkey and use the numeric keyboard or knob to set the lower level of
the new waveform. The lower limit of this le vel is -5 V (50 Ω), a nd the u pper limit
is the maximum which is lower than current setting of the “High VLimit”.
4. Init #Points
When creating a new waveform, the waveform editor will automatically create a
waveform with two points. By default, point 1 is located at 0 seconds and point 2
at half of the spe cified cycle period. In ad dition, the voltages of the two points are
equal to the specified “Low VLimit”.

5. Interp
Press this softkey to enable or disable the interpolation between the defined
waveform points.

not to define the point voltage as the High VLimit or Low VLimit values.
6. Edit Points
Define a waveform by specifying the time and voltage of each waveform point.
Press this softkey to enter the “Edit Points” interface.
PointID: Set the ID of the point to be edited. The default is 1. You can use
the numeric keyboard or knob to modify this parameter.
Time: Set the ti me of the current point. This setting is limited by the time of
the previous and the next points. Note that the time of point 1 is fixed at 0 s.

voltage value is li mited by the “High VLimit” and “Low VLimit” specified in
the initialization. Note that the wavef orm editor wi ll automatically conne ct the
last point to the voltage level of the first point to create a continuous

Insert Point: Insert a waveform point at the middle position of the currently
edited point a nd the next edited point.
Delete Point: Delete the current point from the waveform and connect the
remaining points using the current interpolation method. Note that point 1
cannot be deleted.
7. Edit Block
Define a waveform by editing the time and voltage of the start and end points
and automatically setting the points between them through linear interpolation.
Press Interp to select “Linear”, and then press this softkey to enter the “Edit
Block” interface.
X1: Set the start point (Time) of the block. Note that this value should be
equal to or less than the “Init Points” and X2.
Y1: Set the voltage of the start point in mV or V.
X2: Set the end poi nt (Time) of the blo ck. Note that this value should be less
than or equal to the “Init Points” And be greater than or equal to X1.
Y2: Set the voltage of the end point in mV or V.
Execute: Edit the points within the start and end points according to the
current setting.

8. Save
The currently created waveform is stored in the volatile memory. When creating a
new waveform, the previous waveform in volatile memory will be overwritten.
Press this softkey to enter the file storage interface (refer to “Store and Recall”).
Users can store the edited waveform into internal memory (C Disk) or external
memories (D Disk or E Disk) of the instrument.
Tips
Users can store the waveform edited by PC software into the local memory of
the instrument through the following two methods:
Use SCPI commands (more information, see “

of this
generator).
For waveform with greater than 16 kpts:
:TRACe:DAC VOLATILE16,<flag>,<len>,<binary_block_data>
For waveform with less than 16 kp t s:

To Set Frequency Deviation
Press Deviation to set the frequency deviation of the modulating waveform
frequency relative to the c arrie r waveform frequency.
The frequency deviation must be less than or equal to the carrier waveform
frequency.
The sum of frequency devi ation and ca rrier fre quenc y must be less than or equal
to the sum of upper limit of current carrier frequenc y and 1 kHz.
When external source is selected, frequency deviation is controlled by the ±6 V signal
level of the [Mod In] connector at the rear panel. For example, if the frequency
deviation is set as 1 kHz, +6 V signal level corresponds to a 1 KHz increase in
frequency. Lower external sig nal level generates less deviation, and negative signal
level will reduce the frequency below the carrier waveform frequency.
