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 front panel only allows to output the signal but 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 through the Protective Earth lead of the power cord. To avoid electric 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 high voltage. Improper way of connection could result 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 avoid fire or shock hazard, observe all ratings and markers on the instrument and check your manual for more information about ratings before connecting the instrument.
Use Proper Overvoltage Protection.
Ensure that no overvoltage (such as that caused by a bolt of lightning) 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.

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 maintenance, 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.
To avoid dust or moisture from affecting the performance of the instrument, keep the surfaces of the instrument clean and dry.
Prevent Electrostatic Impact.
Operate the instrument in an electrostatic discharge protective environment to avoid damage induced by static discharges. Always ground both the internal and external conductors of cables to release static before making 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.

Frequency characteristic
Accuracy |
±(1 ppm[1] of the setting value + 10 pHz), 18 to 28 |
Note[1]: ppm denotes one part per million. For example, if the setting frequency is 1MHz and the actual output frequency is between 0.999 998 999 999 999 99MHz and 1.000 001 000 000 000 01MHz, the instrument is up to the specification requirement and the test passes.
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 applicable 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 setting.
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
