General Safety Summary
Please review the following safety precautions carefully before putting the
instrument into operation so as to avoid any personal injury or damage to the
instrument and any product connected to it. To prevent potential hazards, please
follow the instructions specified in this manual to use the instrument properly.
Use the BNC Output Connector Properly.
The BNC output connector on the f ront panel only allows to output the signal b ut not
to input the signal.
Use Proper Power Cord.
Only the exclusive power cord designed for the instrument and authorized for use
within the local country could be used.
Ground the Instrument.
The instrument is grounded th rou gh t he Protective Earth lead of the power cord. To
avoid e lectric shock, connect the earth terminal of the power cord to the Protective
Earth terminal before connecting any input or output terminals.
Connect the Probe Correctly.
If a probe is used, the probe ground lead must be connected to earth ground. Do not
connect the ground lead to hi gh volta ge. Imprope r way of connection could r esult in
dangerous voltages being present on the connectors, controls or other surfaces of
the oscilloscope and probes, which will cause potential hazards for operators.
Observe All Terminal Ratings.
To a void fire or shock hazard, obse rve all r atings an d markers on t he instru ment and
check your manual for more information about ratings before connecting the
instrument.
Use Proper Overvoltage Protection.
Ensure that no over voltage (su ch as that cause d by a bolt of lightni ng) can reach the
product. Otherwise, the operator might be exposed to the danger of an electric
shock.
Do Not Operate Without Covers.
Do not operate the instrument with covers or panels removed.
Do Not Insert Objects Into the Air Outlet.
Do not insert objects into the air outlet, as doing so may cause damage to the
instrument.
Use Proper Fuse.
Please use the specified fuses.

III
Avoid Circuit or Wire Exposure.
Do not touch exposed junctions and components when the unit is powered on.
Do Not Operate With Suspected Failures.
If you suspect that any damage may occur to the instrument, have it inspected by
RIGOL authorized personnel before further operations. Any maint enance,
adjustment or replacement especially to circuits or accessories must be performed
by RIGOL authorized personnel.
Provide Adequate Ventilation.
Inadequate ventilation may cause an increase of temperature in the instrument,
which would cause damage to the instrument. So please keep the instrument well
ventilated and inspect the air outlet and the fan regularly.
Do Not Operate in Wet Conditions.
To avoid short circuit inside the instrument or electric shock, never operate the
instrument in a humid environment.
Do Not Operate in an Explosive Atmosphere.
To avoid personal injuries or damage to the instrument, never operate the
instrument in an explosive atmosphere.
Keep Product Surfaces Clean and Dry.
T o a void dust or moisture from af fecting the pe rformance of the inst rument, keep th e
surfaces of the instrument clean and dry.
Prevent Electrostatic Impact.
Operate the instrume nt i n an el ectr ostatic dischar ge protectiv e e nvi ron ment to a void
damage induced by static discharges. Always ground both the internal and external
conductors of cables to relea s e sta t i c be fore makin g connections.
Use the Battery Properly.
Do not expose the battery (if available) to high temperature or fire. Keep it out of the
reach of children. Improper change of a battery (lithium battery) may cause an
explosion. Use the RIGOL specified battery only.
Handle with Caution.
Please handle with care during transportation to avoid damage to keys, knobs,
interfaces, and other parts on the panels.

Test Procedures
1. Make sure that the environment temperature is between 18℃ and 28℃ and
DG2000 has been warmed up for at least 30 minutes. Connect the channel
output terminal (take CH1 as an example; the test method is also ap plicable to
CH2) of DG2000 with the signal input terminal of the frequency counter using a
dual-BNC cable as shown in Figure 2-1.

2. Turn on the frequency counter and set its output impedance to 1MΩ.
3. Turn on DG2000. When the Shift key is illuminated, press Sine/Preset and
tap the Def icon, then a dialog box is displayed, tap "Apply" to restore DG2000
to the factory settin g.
4. Set DG2000:
a) Set the output waveform of CH1 to a sine waveform with 1MHz frequency
and 1Vpp amplitude.
b) Press Output1 or tap the channel output configuration status bar
to turn on the output of CH1 in the channel setting interface.
5. Record the reading of the frequency counter and judge whether the reading is
between 0.999 998 999 999 999 99MHz and 1.000 001 000 000 000 01MHz.
6. Set CH1 of DG2000 to output square, ramp and pulse waveforms (the
frequencies are 1MHz and the amplitudes are 1Vpp) respectively. Record the
