Safety Requirement

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 t o t he instrument and any product connecte d to it. To prevent potential haza rds, 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 should be used.
Ground The Instrument.
The instrument is grounded through the Protective Earth lead of the power cord. To avoid electric shock, it is e ssential t o connect the ea rth terminal of power cord to the Protective Earth terminal before connecting any inputs or outputs.
Connect the Probe Correctly.
If a probe is used, 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 an d markers on the instrume nt 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.
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 inspected by qualified
II DSG3000 User’s Guide
service personnel before further oper at ions. 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 av oid short circuiting t o the interi or of the device or electric s hock, 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 operat e the dev ice 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 the 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.
Proper Use of Battery.
If a battery is supplied, it must not be exposed to high temperature or in contact 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.
Do Not Overload the Output.
In order to avoid damage to the inst rument, the reverse DC voltage on the RF o utput connector cannot excee d 50 V; the reverse power must be less than +40 dBm (10 W) in the frequency range from 1 MHz to 6 GHz.
Handling Safety.
Please handle with care during transportation to avoid damage to buttons, knob interfaces and other parts on the panels.

external, this connector is used to input the external modulating signal.
14. LF Output Connector
used to output LF signal.
15. RF Output Connector
used to output RF signal and RF sweep signal. When the backlights of RF and MOD go on, this connector is used to output RF modulated signal.
To avoid damage to the instrument, the reverse DC voltage on the RF output connector cannot exceed 50 V, the rev erse power must be less than +40 dBm (10W) in frequency r ange from 1

6. Power Input Connector, Fuse and Switch
The AC power supply specific ation of this signal generator is 100-24 0 V, 45-440 Hz. The power consumption of the instrument cannot exceed 60 W. When the signal generator is connected to AC power supply via this connector, the instrument selects the correct voltage range automatically and users do not need to select the voltage range manually.
The fuse specification of this signal generator is AC 250 V, T2A. If the fuse needs to be replaced, please refer to “To Replace the Fuse
”.
It is used to turn on or off the signal generator.

of LF output is “Ext”, this connector is used to input the external trigger signal. You can set the polarity of trigger signal by pressing Trig Slope to select “Pos” or “Neg”
8. Signal Valid Output Connector
modified, after a certain response and processing time, the internal circuit of the instrument outputs RF signal with specified frequency and amplitude via the RF output connector at the front panel. During this process, the [SIGNAL VALID] connector outputs a pulse sync signal, indicating that the RF output signal is valid. — High Level (+3.3 V): indicates that the RF
signal is in configuration;
— Low Level (0 V): indicates that the RF signal
9. Sweep Output Connector
[SWEEP OUT] connector outputs a signal (0 V
to +10 V) while the RF output connector at the front panel outputs the swe ep signal a ccordin g to the current setting. Each sweep corresponds to
an output cycle.
— When the sweep type is step, this output
— When the sweep type is list, the default of
signal is related to t he choice of sweep shape which can be set to “Triangle” or “Ramp”.
