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 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 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 lectr ic 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. Imp roper w ay of connection could resul t 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 avoi d fi re or s hock haza rd, observe all ratings an d ma rkers on the i nstrume nt and
check your manual for more information about ratings before connecting the
instrument.
Use Proper Overvoltage Protection.
Ensure that no over voltage (such as that caused by a bolt of lightning ) can rea ch 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.
II VSA User's Guide
RIGOL
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 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 av oid dust or mois ture from affecting the performance of the instrument, ke ep the
surfaces of the instrument clean and dry.
Prevent Ele c tr o static Imp a ct.
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. Alwa ys g rou nd 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 childre n. Imprope r cha nge 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.

RSA5000 provides four workin g modes: GPSA, R TSA, VSA (option), and EMI (option).
Press Mode to select the working mode.
Note: In different working modes, the functions of the keys on the front panel may
be different. Press Help to dis play the help information of the current working mode.
If you need help information for other modes, please exit the help interface firs t.
Then select the desired wor king mode and obtain the corresponding help
information.
1. GPSA
GPSA adopts two analysis methods: swept SA and FFT. It can not only carry out
frequency domain analysis, but also time domain (zero span) analysis.
Select GPSA. In this working mode, you can press Meas to select multiple
measurements. For details, refer to relevant chapters in Chapter 2 of
User's Guide
2. RTSA
RTSA provides the analysis function for the real-t im e signal, which can captu r e
the complex signal seamlessly.
Select RTSA. In this working mode, you can also press Meas to select multiple
measurements. For details, refer to relevant chapters in Chapte r 2 of
User's Guide
3. VSA
VSA mode provides the standard v ector signal a nalysis measurement function. I f
you need this function, please purchase this option (or der No . RSA5000-VSA),
and install it according to instructions in "Install the Option".
4. EMI
EMI mode provides the EMI precompatibility measurement function. If you need
this function, please purchase this option (order No .

Mode Setup
The Mode Setup menu is used to set parameters related to the working modes.
Open the global parameter setting menu for the selected working mode under
Mode.
1. Global CF Mode
Turns on or off the global center frequency. In any working mode, if you enable
the global center frequency mode, then the global center frequency will be set
to the center frequency of the current mode. When a different working mode is
selected, the global center frequency will be set to the center frequency of the
previous working mode, that is, the one that is before switching the working
mode. If you chan ge the center f requency in any working mode, then the global
center frequency will chang e with it.
2. Global CF
Sets the global center frequency. It is only available when you turn o n the global
center frequency.
3. Mode Preset
Resets the parameters of the current mode to be the factory default settings.
Install the Option
RSA5000 pr ovides various options (for option information, refer to "Accessories
and Option List") to expand the function o f the spectrum analyzer. If you need to
purchase the option, please contact RIGOL sales representative. After you have
purchased the option suc cessfully, perform the following operations to install the
option.
1. Acquire the license of the option
Log in to the RIGOL officia l webs i te (www.rigol.c om), click License
