Safety Notice

Please review the following safety precautions carefully before putting the instrument into operation so as to avoid any personal injuries or damages to the instrument and any product connected to it. To prevent potential hazards, please use the instrument only specified by this manual.

Use Proper Power Cord

Only the power cord designed for the instrument and authorized by 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 essential to connect the earth terminal of power cord to the Protective Earth terminal before any inputs or outputs.

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.

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.

II

Do Not Operate Without Covers

Do not operate the instrument with covers or panels removed.

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 service personnel before further operations. Any maintenance, adjustment or replacement especially to circuits or accessories must be performed by RIGOL authorized personnel.

Do Not Operate in an Explosive

Atmosphere

In order to avoid damages to the device or personal injuries, it is important to operate the device 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 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.

Protect the Input Terminals of

Do not bend or hit the input terminals and the connected devices, (such as filter, attenuator, etc.) as such stress may cause damages to devices and the instrument. Do not mix the use of 50Ω and 75Ω connectors and/or cables.

Do Not Overload the Input

To avoid damaging the instrument, the signals at input terminal must be less than 50V DC voltage components and 30 dBm (1 W) AC (RF) components.

Appropriate Use of Power Meter

If you are not sure of the characteristics of signal under measure, follow these recommendations to ensure safe operations: if a RF power meter is available, use it to measure the power level of this signal first; or add a rated external attenuator between signal cable and input terminal of the instrument.

Maximum attenuation, reference level and maximum span frequency should be selected, so as to make the signals displayed within the screen.

Know About the Specification

Conditions of the Instrument

For maximum performance of the instrument, use the analyzer under specified conditions.

Proper Use of Battery

The battery 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.

2.1.1 FREQ

Sets the frequency parameters of the analyzer. The analyzer sweeps within a specified frequency range, and the sweep is restarted every time you change this parameter.

The frequency range of a channel can be expressed by either of two groups of parameters: Start Frequency and Stop Frequency; or Center Frequency and Span. If any such parameter is changed, the others would be adjusted automatically in order to ensure the coupling relationship between them.

2.1.1.1 Center Freq

Sets the center frequency of the sweep. When pressed, the frequency mode is switched to Center Freq and Span in order to enter the desired parameter data. In this mode, parameters you specified are always shown at the lower right and the left side of the display grid.

Key Points:

 The start and stop frequencies vary with the center frequency when the span is constant.

 Changing the center frequency horizontally shifts the current sweep channel.

 In Zero Span mode, the start frequency, stop frequency and center frequency are always equal. If one is changed the others are updated to match.

 You can modify this parameter using the numeric keys, knob, or direction keys.

2.1.1.4 CF Step

Sets the step magnitude of center frequency. Changing the center frequency in a fixed step continuously switches the channel to be measured.

Key Points:



The CF step type could be “Manual” or “Auto”. In Auto mode, the CF step is 1/10 of span if it is in Non-zero span mode or equals the RBW while in Zero span mode; in Manual mode, you can set the step using the numeric keys.

 After you set an appropriate CF step and select Center Freq, pressing the

Forward or Reverse key from the Channel menu or using up and down direction keys to switch between measurement channels in a specified step in



RIGOL order to sweep the adjacent channels manually.


For more details, please refer to “Parameter Input”.

Application

CF step lends itself to detect the harmonic waves and bandwidths that are beyond the current span.

For example, for each order of harmonic of a 100 MHz signal, we can set both the center frequency and CF step to 100 MHz, and press Reverse continuously to show the harmonics sequentially at the center of the frequency display.

2.1.1.5 Signal Track

Tracks signals with unstable frequency and less than 3 dB transient variation in

amplitude by placing the Marker1 (see Marker Measurements) onto the measured

signal to track the variation continuously.

The system tracks a signal according to the following steps:

Key Points:

 When Signal Track is On, the system will execute peak search after every sweep, and set the frequency of current peak to center frequency, displaying signal at the center of screen all the time.

 When Signal Track is On, an icon

is shown at the left of screen. The signal will always stay at the screen center unless its amplitude changes by more than 3 dB between sweeps.

 If no marker is active, pressing this key will activate Marker 1 and execute a peak searching automatically; meanwhile the center frequency is used as the frequency of marker 1.

 In Continue sweep, the system tracks continuously; in Single sweep, only one track is done; in Zero Span, Signal Track is invalid.

2.1.2 SPAN

Sets the span value of the analyzer. The changing of this parameter will affect others parameters associated with the FREQ function, and restart the sweep.

2.1.2.1 Span

Sets the frequency range of the sweep. When pressed, the frequency mode is switched to Center Freq and Span in order to enter the desired parameter data. In this mode, parameters you specified are always shown at the lower left and the right side of the display grid.

Key Points:

 The start and stop frequency are changed with the span automatically.



In manual span mode, the span can be set down to 100 Hz (the only way into the zero-span mode is to press the Zero Span menu option) and up to the full span described in the specification.

 Modifying the span in non-zero span mode may cause an automatic change in both CF step and RBW if they were in Auto mode, and the change of RBW may influence VBW (in Auto VBW mode).

 Any variation in the span, RBW and VBW may cause a change in sweep time.

 In non-zero span mode, neither “Video” trigger nor “1/Δtime” readout function is valid.

2.1.2.2 Full Span

Sets the span of the analyzer to the maximum.

2.1.2.3 Zero Span

Sets the span of the analyzer to 0 Hz. Both the start and stop frequency will equal the center frequency and the horizontal axis will denote time. The analyzer here is measuring the time domain characteristics of amplitude, located at the corresponding frequency point.

Key Points:

As opposed to the Non-zero span, the screen shows the time domain characteristics of the fixed frequency component, and following functions are invalid in Zero span mode:

 FREQ: Peak->CF, Signal Track and Channel setting;

 SPAN: Zoom In and Zoom Out;

 Marker->: Mkr->CF, Mkr->Step, Mkr->Start, Mkr->Stop, MkrΔ->CF and

MkrΔ->Span;

 Marker: Readout  Frequency, Period and 1/ΔTime (valid in Delta marker type)

2.1.2.4 Zoom In

Sets the span to the half of its current value (down to the minimum).

2.1.2.5 Zoom Out

Sets the span to twice the current value (up to the maximum).

2.1.2.6 Last Span

Changes the span to the previous span setting.



RIGOL

2.1.3 AMPT

2.1.3.5 Scale Type

Sets the Scale Type of Y-axis to Lin or Log, the default is Log.

Key Points:

 In Log scale type: the Y-axis denotes the logarithmic coordinates, the value shown at top of the grid is the reference level and the grid size is equal to the scale value. The unit of Y-axis will be automatically switched into the default

“dBm” when the scale type is changed from Lin to Log.



In Lin scale type: the Y-axis denotes the linear coordinates, the value shown at the top of the grid is the reference level and the bottom of the grid shows 0 V. The grid size is 10% of the Reference level and the Scale/Div is invalid. The unit of

Y-axis will be automatically switched into the default “Volts” when the scale type is changed from Log to Lin.



Other than as mentioned above, the unit of Y-axis is independent of the Scale

Type.

2.1.3.6 Units

Sets the unit of the Y-axis to dBm, dBmV, dBuV, Volts or Watts. The units dBm, dBmV, and dBuV are for Log scaling; Volts and Watts are for Linear scaling. The default is dBm.

2.2.1 BW

Sets the RBW (Resolution Bandwidth) and VBW (Video Bandwidth) parameters of the analyzer.

2.2.1.1 RBW

Sets the desired resolution bandwidth in order to distinguish between signals which are close in frequency.

Key Points:



Reducing the value of RBW will increase the frequency resolution, but may also cause sweeps to take longer (Sweep Time is effected by a combination of RBW and VBW when it is in Auto mode).

 RBW decreases with the span (non-zero span) in Auto RBW mode.

2.3.2 Trace

As the sweep signal is displayed as a trace on the screen, you can set parameters about the trace using this key. The analyzer allows for up to four traces to be displayed at one time, and each trace has its own color (Trace 1 - Yellow, Trace 2 - purple, Trace

3 – light blue and Trace 4 - green). All traces can be set freely except Trace 4 (a math operation trace that can only be obtained using the other three traces).

2.3.2.1 Select Trace

Selects Trace 1, Trace 2 or Trace 3 in order to set parameters associated with each.

The default trace and type is Trace 1 and Clear Write.

2.3.2.2 Trace Type

Sets the type of the current trace or disables it. The system calculates the sample data using a specific operation according to the selected type and displays the result. Trace type contains Clear Write, Max Hold, Min Hold, Video Avg, Power Avg, Freeze and

Blank. Every type has its own parameter icon that shown on the left of screen. Take

Trace 1 as an example and see the following icons.

1. Clear Write

The trace continuously displays the points during the sweep of the analyzer.

2. Max Hold

Maintains the maximum for each point of the trace, and updates each trace point if a new maximum is generated in successive sweeps.

3. Min Hold

Maintains the minimum for each point of the trace, and updates each trace point if a new minimum is generated in successive sweeps.



RIGOL

4. Video Avg

Displays the trace after a logarithmic mean is calculated for each point of the trace in successive sweeps. Traces in this type will be smoother.

5. Power Avg

Displays the trace after an averaging of each point of the trace in successive sweeps. Traces in this type are smoother than others.

6. Freeze

Stops updating trace data in order to observe the trace and read the measurement data. This type is generally used by traces from the storage devices or remote interface as default.

7. Blank

Disables the trace display and all measurements under this trace.

2.3.2.3 Average Times

Sets the number of times to average the selected trace.

Key Points:

 More averaging may reduce the noise and influence of other random signals, potentially displaying more stable signal characteristics. The larger the number of times to average, the smoother the trace will be.

Readings

Figure 2-24 Schematic of the marker

Key Points:

 The analyzer allows for up to four groups of markers to be displayed at one time, but only one pair or one single marker is active every time.

 You can use the numeric keys, knob or direction keys to enter the desired frequency or time when any marker type menu is active, so as to view the readout of different points on the trace.

One of the marker types, which is used to measure the values of X (Frequency or Time) or Y (Amplitude) at certain point of the trace. When selected, a marker will appear with its own digital ID such as “1” on the trace.

Key Points:

 If no active marker existed currently, a one will be enabled automatically at the center frequency of current trace.

 You can use the knob, direction keys or numeric keys to move the marker. The readouts of the marker will be displayed on the upper right of the screen.



The readout resolution of the X-axis corresponds to the span and sweep points.

For higher resolution, adding sweep points or reducing the span.


RIGOL


2.5.1.3 Delta

One of the marker types, which is used to measure the delta values of X (Frequency or

Time) and Y (Amplitude) between the Reference point and certain point on the trace.

When selected, a pair of markers appears on the trace, which are the Reference

Marker (marked as a combination of the marker number and letter “R”, such as “1R”) and the Delta Marker (marked as the marker number, such as “1”).

Key Points:

 The Reference Marker will be activated at the position of current marker, or else both the reference marker and Delta Marker will be simultaneously activated at the center frequency location if no marker is active at the present.

 The location of the Reference Marker is always fixed (both in the X-axis and the

Y-axis), while the Delta Marker is active. You can use the numeric keys, knob or direction keys to change the location of Delta Marker.

 The delta of both the frequency (or Time) and the amplitude between the two markers that displayed at the upper right of the screen.

 One way to enable a certain point as the reference is to open a “Normal” marker and locate it onto a point and then switch the marker type into “Delta”, creating a new reference, then you can modify the location of the delta point to achieve the delta measurement; the other way is to open a Delta Marker and place it onto a point, then reselect the Delta menu to locate the marker you opened onto this point.

 If you activate the Noise Mkr function under the Marker Fctn key, the result of the noise measurement will be corrected automatically and normalized to 1 Hz.

The application of Delta marker

Measuring the signal-noise ratio of single spectrum signal, for example, separately place the Reference and Delta Marker onto the signal and noise, the amplitude shown in the measurement result is the signal-noise ratio.



RIGOL

2.5.1.4 Delta Pair

One of the marker types. When selected, a pair of markers will appear on the trace, which are the Reference Marker (marked as a combination of the marker number and letter “R”, such as “1R”) and the Delta Marker (marked as the marker number, such as

“1”).

Key Points:

 You can use the knob, direction keys or numeric keys to set the location of the

Reference Marker (selecting Ref) and the Delta Marker (selecting Delta).

 This is different from the Delta type marker in that you can modify both the

Reference and Delta Marker. Additionally, both the X and Y value of the Reference

Marker are stable in “Delta” type during the sweep, but the Y value of the

Reference Marker is updating along with the sweep in “Delta Pair” type.

2.5.1.5 Span Pair

One of the marker types. When selected, a pair of markers will appear on the trace, which are the Reference Marker (marked as a combination of the marker number and letter “R”, such as “1R”) and the Delta Marker (marked as the marker number, such as

“1”).

Key Points:

 You can use the knob, direction keys or numeric keys to set the location of both the Reference Marker and Delta Marker at the same time.

 If Span is selected, setting the Span Pair will keep the center position of the two markers and move them towards the two sides (value increasing) or the middle

(value decreasing).

 If Center is selected, setting the Span Pair will keep the relative distance of the two markers and move their center position towards the left (value decreasing) or right (value increasing).

 This is different from the “Delta” type marker, in that you can modify both the

Reference Marker and Delta Marker at the same time.

2.5.1.7 Mkr Trace

Selects a trace to be used on the current marker from 1, 2, 3, Math or Auto. When

Auto is selected, the system searches the desired trace in the order of Clear Write,

Max Hold, Min Hold, Video Avg, Power Avg, Freeze, and then selects one of them in sequence of the trace number 1, 2 and 3 if more than two traces are found.

2.5.1.8 Readout

Selects a desired readout type of X-axis for the marker from Frequency, Period, ΔTime and 1/ΔTime. Note this setting will cause a change in the type of readout but not in actual value. The type you select may also affect the marker readout shown on the active area and the upper right of screen.

1. Frequency

In this type, a Normal marker shows the absolute frequency and a Delta marker shows the frequency difference between the Delta Marker and Reference Marker.

The default readout in non-zero span mode is Frequency.

2. Period

In this type, a Normal marker shows the reciprocal value of frequency and the other types show the reciprocal value of frequency difference. When the frequency difference is zero, the displayed value is infinite (with 10 Ts displaying).

Note this type is invalid in Zero span mode.

3. ΔTime

In this type, a Normal marker shows the time difference between where the marker is located and the start of the sweep, while a Delta marker shows the sweep time difference between the Delta Marker and Reference Marker.

The default readout in Zero span mode is ΔTime.



RIGOL

4. 1/ΔTime

In this type, the reciprocal value of sweep time difference between the Delta

Marker and Reference Marker will be shown. When the time difference is zero, the displayed value is infinite (with 100THz displaying). Note this type is available only in Zero span mode when a Delta type marker is selected and suitable for the frequency measurement of a video signal.

2.5.1.9 Marker Table

2.5.4.6 Cont Peak

Enables or disables the Cont peak search, the default is Off. When enabled, the system will always execute a peak search automatically after each sweep in order to track the signal under measurement.

The difference between the Cont peak and the Signal Track

The Cont peak focuses on the searching for the maximum in the current channel, while the Signal Track always searches for the signal that has the same amplitude as the one which was located at the current marker before the Signal Track was enabled, and uses the frequency of this signal as the center frequency.

2.5.4.7 Search Para

Defines the conditions of peak search for various peak searching. A real peak should meet the value of both “PK Excursn” and “PK Thresh”.

1. PK Excursn

Sets the excursion between the peak and the minimum amplitude on both sides of it. A real peak should always be beyond the excursion you specified.

2. PK Thresh


RIGOL

5. Prompt Message:

The instrument may give common prompts, error prompts, or state prompts according to the current status to assist in proper use of the analyzer or to show warnings that some fault might happen to the instrument.



5.2 Messages

Messages fall into three types on the basis of the tips purpose: Information Message,

Error Message, and Status Message. To get accurate measurements and specific working status of the analyzer, you should be familiar with these messages.

1. Information Message: to give a clue that the current task has finished or the analyzer has entered a specified state. The messages are always marked with an

icon and displayed on the screen for several seconds and then hidden automatically, or you can press any key to clear the display of this massage.

Message number: 1 - 199.

2. Error Message: to warn you that the current operation cannot be executed and has been ignored or paused for some reason. These messages are always marked with an icon and displayed on the screen for several seconds and then hidden automatically, or you can press any key to clear the display of this error massage.

Error Messages based on the cause of the error are divided into Command Error,

Execution Error, Device Specific Error, or Query Error. Each of the errors corresponds to a specific bit pattern in the Standard Event Status Register (see

IEEE 488.2,11.5.1). When you find there is an error generated in the Standard

Event Status Register, send command SYSTem:ERRor? in Remote Mode to get the information on this error and find the cause of it.

(1) Command Error: indicates a command error is detected by the Parser while in Remote control (see IEEE488.2,6.1.6), possible reasons are:

 The Parser detects a syntax error; (see IEEE488.2,7.1.2.2)

 An unrecognized header or a parameter that is of the wrong type for its associated header is received. (see IEEE488.2,10)

Message number: -199 to -100.

(2) Execution Error: indicates an execution error is detected by the Execution

Control Block, possible reasons are:

 A parameter following a header was evaluated by the device as outside of its legal input range or is otherwise inconsistent with the device’s capabilities.

 A valid program message could not be properly executed due to some



device condition.


(3) Device Specific Error: indicates a device specific error is generated when the commands cannot be correctly executed due to current settings of the hardware and software of the device.

Message number: -399 to -300 (defined in SCPI standard) and 300 to 1000.

(4) Query Error: indicates a query error is generated when the output queue controller (see IEEE488.2,6.5.7) fails to follow the Message Exchange

Control Protocol under any of the conditions below: ( see IEEE488.2,6.1.10)

 When trying to read the output queue, the queue has no data or is being suspended.

 Data in the output queue has been lost.


3. Status Message: to warn you that the analyzer is now in a certain condition and should be paid attention to. The messages are always marked with an icon and displayed on the screen until the ESC key has been pressed or the *CLS command is used. The messages are stored in corresponding status register, and can be queried by sending Status: or SYSTEM:ERROR[:NEXT]?.

Message number: 200 to 299.

5.2.2 Error Message

5.2.2.1 Command Error


0

-100

Everything is OK.

Command error.

-101

This is a generic syntax error for devices that cannot detect more specific errors. This code indicates only that a Command Error as defined in IEEE 488.2,11.5.1.1.4 has occurred.

Invalid character.

A syntactic element contains a character which is invalid for that type; for example, a header containing an ampersand, SETUP&. This error might be used in place of errors -114, -121, -141, and perhaps some

-102

-103

-104

-105

-108

-109

others.

Syntax error.

An unrecognized command or data type was encountered; for example, a string was received when the device does not accept strings.

Invalid separator.

The parser was expecting a separator and encountered an illegal character; for example, the semicolon was omitted after a program message unit, *EMC 1:CH1:VOLTS 5.

Data type error.

The parser recognized a data element different than one allowed; for example, numeric or string data was expected but block data was encountered.

GET not allowed.

A Group Execute Trigger was received within a program message (see

IEEE 488.2, 7.7).

Parameter not allowed.

More parameters were received than expected for the header; for example, the *EMC common command only accepts one parameter, so receiving *EMC 0, 1 is not allowed.

Missing parameter.

Fewer parameters were received than required for the header; for example, the *EMC common command requires one parameter, so receiving *EMC is not allowed.

Suffix error.

This error, as well as errors -131 through -139, are generated when parsing a suffix. This particular error message should be used if the device cannot detect a more specific error.

Invalid suffix.

The suffix does not follow the syntax described in IEEE 488.2, 7.7.3.2, or the suffix is inappropriate for this device.

Suffix too long.

The suffix contained more than 12 characters (see IEEE 488.2, 7.7.3.4).

Suffix not allowed.

A suffix was encountered after a numeric element which does not allow suffixes.

Character data error.

This error, as well as errors -141 through -149, are generated when parsing a character data element. This particular error message should be used if the device cannot detect a more specific error.

Invalid character data.

Either the character data element contains an invalid character or the particular element received is not valid for the header.

Character data too long.

The character data element contains more than twelve characters (see

IEEE 488.2, 7.7.1.4).

Character data not allowed.

A legal character data element was encountered where prohibited by the device.
