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 to t he
instrument and any product connecte d to it. To prevent potential hazards, please us e
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 e ssential t o connect the ea rth terminal of the 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
isobaric electric potential as the 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 the
instrument.
Use Proper Overvoltage Protection.
Make sure that no overvoltage (such as that caused by a t hunderstorm) can reach
the product, or else the operator might be exposed to the 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.
II DSG800 User's Guide
RIGOL
Do Not Operate With Suspected Failures.
If you suspect damage occurs to the instrument, have it inspected by RIGOL
authorized personnel before further oper at io ns. Any maintenance, adjustment or
replacement especially to circuits or accessories must be performed by RIGOL
authorized personnel.
Keep Well Ventilation.
Inadequate ventilation may cause an increase of instrument temperature which
would cause damage to the instrument. So please keep the instrument 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 shock, please
do not operate the instrument in a humid environment.
Do Not Operate in an Explosive Atmosphere.
In order to avoid damage to the device or personal injuries, it is i mportant to o perate
the device away from an explosive atmosphere.
Keep Product Surfaces Clean and Dry.
To avoid the influence of dust and/or moisture in the air, please keep the surface of
the device clean and dry.
Electrostatic Prevention.
Operate the instrument in an electrostat ic discharge protective environ ment to a void
damage induced by static discharges. Always ground both the internal and external
conductors of cables to release static before making connections.
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 batte ry only.
Handling Safety.
Please handle with care during transportation to avoid dam age to keys, knob
interfaces and other parts on the panels.

Point Trigger Mode. For example, when
input from the [TRIGGER IN] connector (as shown in the figure below) at
the rear panel. If the sweep mode is set to "Cont", the instrument starts to
sweep a point each time a TTL pulse signal with the specified polarity is
received. If the sweep mode is set to "Single", you need to press Single to
meet the single sweep condition; aft er that, the instrument starts to sweep
a point and then stops after the sweep period expires each time a TTL puls e
signal with the specified polarity is received.
To specify the polarity of the TTL pulse signal, press Trig Slope to select

When executing the s weep o perat ion, the priorit y order of the conditions is
Single Sweep Trigger Mode
both the trigger mode and point trigger mode are set to "Key" trigger:
In "Cont" sweep mode, you need to press Key Trig to meet the
trigger mode of the whole period and then press Key Trig again to
meet the trigger mode of the points within the swee p period; then, the
instrument starts to sweep.
In "Single" sweep mode, you need to press Single to meet the single
sweep condition and then press Key Trig twice to meet the sweep
period trigger mode and point trigger mode respectively; then, the
instrument starts to sweep.

To Set the Modulation Depth
The modulation depth denotes the extent of output amplitude variation and is

Press Depth to set the AM modulation depth.
1. When "Int" modulation source is selected
The AM modulation depth (
) and the amplitude difference (

When the modulation depth is 0%, the instrument outputs a carrier signal
with a single frequency point.
The greater the modulation depth is, the smaller the difference between the
output amplitude and carrier amplitude will be.
2. When "Ext" modulation source is selected

(4) If the USB storage device still cannot be used normally, please contact
RIGOL.
7. No response or incorrect response when a key is pressed:
(1) After starting the instrument, check whether all the keys are irresponsive.
(2) Press Syst Self-Test Key Test to enter the keyboard test interface.
Press the function keys at the front panel sequentially and check whether
some key gives no response or incorrect response when it is pressed.
(3) If the above failures o ccur, the keyb oard c onnecting wire might be l oose o r
the keyboard is damaged. Please do not disassemble the instrument and
contact RIGOL.
8. The instrument does not pass the performance specification test:
(1) Check whether the RF signal generator is within the calibration perio d (1
year).
(2) Check whether the RF signal generator is w armed up for at least 40 minutes
before the test.

RIGOL Chapter 5 Troubleshooting
(3) Check whether the RF signal generator is working under the specified
environment temperature.
(4) Check whether the test is being performed in a highly magnetic
environment.
(5) Check whether the power supplies of the RF signal generator and test
system have strong interference.
(6) Check whether the performanc e of the test device meets the requirement.
(7) Check whether the test device is within the calibration period.
(8) Check whether the test device is working under the required conditions of
the corresponding manual.
(9) Check whether all the connections are tight.
(10) Check whether the cables have internal damage.
(11) Make sure that the operations conform to the settings and processes
required by the performance verification guide.
(12) Check whether the error calculation is correct.
(13) Get a correct understanding of the definitions of "Typical Value" and
"Nominal Value".
— Typical Value: the performance specifications of this product under the
specified conditions.
— Nominal Value: the approximate quantity of the product during
application.

Chapter 6 Specifications RIGOL
Chapter 6 Specifications
This chapter lists the technical specifications and general specifications of the RF
signal generator. The technical specifications are valid when the instrument is within
the calibration period, is stored for at least two hours in 0℃ to 50℃ temperature
and is warmed up for 40 minutes. Unless otherwise noted, the specifications in this
manual include the measurement uncertainty.
Typical Value (typ.): the typical performance that 80 percent of the measurement
results can meet at room temperature (approxim a tely 25 ℃). This data is not
warranted and does not include the measurement uncertainty.
Nominal Value (nom.): the expected average performance or the designed
performance attribute (for example, the 50 Ω connector). This data is not warranted
and is measured at room temperature (approximately 25℃).
Measured Value (meas.): the performance attribute measured during the design
phase and used to be compared with the expected performance (for example, the
variation of the amplitude drift with time). This data is not warranted and is
measured at room temperature (approximately 25℃).
Note: Unless otherwise noted, all the values in this chapter are the measure men t
results of multiple instruments at room temperature.
