Mode Setup
The Mode Setup menu is used to set parameters that are related to the working modes.
Open the global parameter setting menu for the selected working mode under
Mode.
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 change the center frequency in any working mode, then the global center frequency will change with it.
Global CF
Sets the global center frequency. It is only available when you turn on the global center frequency.
Mode Preset
Resets the parameters of the current mode to the factory default settings.
EMC Standard (Only Available for EMI Mode)
Sets the EMC standard to "None" or "CISPR".
When "None" is selected, the filter type is set to Gauss. At this point, the filter bandwidth is -3 dB. The instrument will switch to "CISPR" standard automatically when "Quasi Peak", "CISPR Average" or "RMS Average" detector is selected. The filter type is set to EMI. At this point, the filter bandwidth is -6 dB.
When "CISPR" is selected, for Meter 1, the detector is, by default, positive peak; for Meter 2, the detector is, by default, quasi peak; for Meter 3, the detector is, by default, CISPR average.

f stop
); or Center
Frequency/Span (
f center
/

Center Freq
Sets the center frequency (that corresponds to the horizontal center of the graticule) of the current channel. Press this key or touch the specified menu item on the screen to set the frequency entry mode to Center Frequency/Span. The center frequency and span values are respectively displayed at the lower left and right side of the graticule.
Remarks:
When you modify the center frequency, the start and stop frequency will be modified automatically if the span remains to be unchanged.
Modifying the center frequency indicates that the frequency is changed along the current channel horizontally, and the adjustable range should be within the frequency range specified in the technical specifications of the analyzer.
In zero span mode, the values of start frequency, stop frequency, and center frequency are the same, so once one of the parameter values is modified, the other two values will be modified automatically.
You can use the numeric keys, the knob, and the arrow keys on the front panel to modify this parameter; also you can modify it on the touchscreen. For details,

Remarks:
If an active marker currently exists, when Signal Track is enabled, the instrument will search for and mark the point (whose amplitude variation is less than 3 dB) near the marker. Then, set the frequency at this point to be the center frequency to keep the signal at the center of the screen.
If no marker is currently active, when Signal Track is enabled, the instrument will activate Marker1, execute a peak search automatically, and set the frequency value at the current peak to be the center frequency to keep the signal always displayed at the center of the screen.
In continuous sweep, the system tracks the signal continuously; in single sweep, the instrument only performs a single signal track.
The signal tracking function is only applicable to the swept analysis. The signal tracking function is invalid in the following conditions:
—
In zero span mode;
—
When the tracking generator is enabled;
—
When the trace is not updated;
—
When the continuous peak search is enabled;
—
In advanced measurement mode.

SPAN
Sets the span of the analyzer. Changing this parameter will change the frequency parameters, and after the span is changed, the sweep restarts.
Span
Sets the frequency range of the current channel. Press this key or touch the specified menu item on the screen to set the frequency entry mode to Center Frequency/Span.
The center frequency and span values are respectively displayed at the lower left and right side of the graticule.
Remarks:
When you modify the span, the start and stop frequency will be modified automatically, with the center frequency remains to be unchanged.
In non-zero span, the span can be set to a minimum of 10 Hz. When the span is set to a maximum value, the spectrum analyzer enters the full span mode.
You can set the span to 0 Hz manually; you can press the Zero Span menu item or run the SCPI commands to enter the zero span mode.
When you modify the span in non-zero span mode, both CF step and RBW will be changed automatically if they are in Auto mode. Besides, the change of RBW will change the value of VBW (in Auto VBW mode).
Any variation in span, RBW, or VBW would cause a change in the sweep time.

Zero Span
Sets the span to 0 Hz. The values of start frequency and stop frequency are the same as that of the center frequency. The X-axis is time. The analyzer measures the time-domain characteristics of the amplitude at the center frequency point of the input signal.
Remarks:
The zero span mode displays the time-domain characteristics of the signal's fixed frequency components. Great differences can be found between the zero span and the non-zero span. The following functions are invalid in zero span.
"Signal Track" under FREQ;
"Mkr -> CF", "Mkr -> CF Step", "Mkr -> Start", "Mkr -> Stop", "Mkr Δ -> CF", and "Mkr Δ -> Span" under Marker To;
AMPT
Sets the amplitude parameters of the analyzer. You can modify these parameters to make the signals under test be displayed with minimal errors in the current window, easy for you to observe.
Ref Level
Sets the maximum power or voltage that can be displayed in the current window.
Remarks:
As the RF link is limited by the maximum mixer level, when the attenuation is reduced, the reference level will be reduced to meet the limitation of the mixer level; when the attenuation is increased, the reference level will remain unchanged.

Attenuation
Sets the RF front-end attenuator to allow high-level signals to pass through the mixer with low distortion, and low-level signals to pass through the mixer with low noise.
Remarks:
The attenuator consists of fixed attenuator and variable attenuator. The attenuation of the fixed attenuator is 20 dB, and the attenuation range of the variable attenuator is from 0 dB to 30 dB. Therefore, the input attenuation ranges from 0 dB to 50 dB.
When the set attenuation amount is greater than 20 dB, fixed attenuator is preferred to be used by default.

Scale Type
Sets the scale type of the Y-axis to Lin or Log. By default, it is Log.
Remarks:
In Log scale type, the Y-axis denotes the logarithmic coordinate. The top line of the graticule is the reference level, and the scale per division represents the scale value. When the scale type is changed from Lin to Log, the unit of Y-axis will automatically switch to the default unit (dBm) in Log scale type.
In Lin scale type, the Y-axis denotes the linear coordinate. The top line of the graticule is the reference level, and 0 V is at the bottom of the graticule. Each vertical division of the graticule represents one-tenth of the reference level. The scale setting function is invalid. When the scale type is changed from Log to Lin, the unit of Y-axis will automatically switch to the default unit (Volts) in Lin scale type.
The scale type does not affect the unit of Y-axis.
If the "Normalize" function is enabled, "Log" is selected to be the scale type by default, and the scale type is grayed out and disabled.
Scale/Div
Sets the logarithmic units per vertical grid division on the display. This function is only available when the scale type is set to "Log".
Remarks:
The amplitude range to be displayed can be adjusted by setting the scale.

In non-zero span mode, the analyzer selects the shortest sweep time based on the current RBW and VBW settings if "Auto" is selected.
Decreasing the sweep time can speed up the measurement. However, an error may be caused if the set sweep time is less than the minimum sweep time in
Auto coupling. At this point, "UNCAL" is shown in the status bar on the screen.
In zero span mode, the Sweep Time Mode menu is disabled and grayed out.
When the system exits the zero span mode, the auto sweep coupling mode will restore to its previous state.
When RBW is smaller than 1 kHz, the spectrum analyzer starts to perform FFT sweeps. At this time, the Sweep Time menu is disabled and grayed out.
Sweep Time Rule
Sets the sweep type to "Norm" or "Accy". The sweep will be faster if "Norm" is selected; while in "Accy" type, a higher measurement precision can be obtained.
When RBW is smaller than 1 kHz, the spectrum analyzer starts to perform FFT sweeps. At this time, the Sweep Time menu is disabled and grayed out.

Detector Type
Sets the detector for the current measurement. The selected detector can be applied to the selected trace. The available trace detectors include Pos Peak, Neg Peak,
Normal, Sample, Average (RMS), and Average (Vol).
1.
Pos Peak
For each trace point, Positive Peak detector displays the maximum value of data sampled within the corresponding time interval.
2.
Neg Peak
For each trace point, Negative Peak detector displays the minimum value of data sampled within the corresponding time interval.
3.
Normal
Normal detector (also called Rosenfell detector) displays the maximum value and the minimum value of the sample data segment in alternating sequence.
That is, for an odd-numbered data point, the minimum value of the sample data is displayed; for an even-numbered data point, the maximum value of the sample data is displayed. In this way, the amplitude variation range of the signal is clearly shown.
4.

Quasi Peak (Option)
Quasi-peak detection is a weighted form of peak detection. For each data point, the detector detects the peak in the corresponding time interval, and uses quasi-peak detector circuit (containing specific charge and discharge structure) and the time constants specified in CISPR Publication 16 to make weighted calculation to display the weighted results. The quasi-peak detection is used for
EMC test.
Note: The charge time for the quasi-detector is much shorter than the discharge time, which can not only reflects the amplitude of the signal, but also the time distribution of the signal.

When inactive trace is displayed, the trace will not be zoomed in or out based on the setting of X-axis, but will move up and down based on the changes of Y-axis values.
When the trace is shifted from inactive to active state, the trace is cleared, the average timer is reset, and a new sweep is restarted.
Math Function
Trace math functions perform mathematical operations between traces and, in some cases, user-defined offsets.
1.
Op1-Op2
Calculates the power difference between Operand 1 (Op1) and Operand 2 (Op2), and saves it to the destination trace. During the sweep, the following formula is executed for each point:

−
10
(Op2 10)

(2-10)
In the above formula, the parameter unit is dB. If a point in Op1 is a maximum trace value, the difference (the result of the subtraction) is also a maximum trace value; if the difference is less than or equal to 0, the resultant point is the minimum trace value.
2.
Op1+Op2
Calculates the power sum between Operand 1 (Op1) and Operand 2 (Op2), and saves it to the destination trace. During the sweep, the following formula is executed for each point:

Avg Mode
The average modes include "Log", "RMS", and "Scalar".
Log: In this mode, all filtering and averaging processes select the log unit
(dB). This average type is the most effective one for finding the low-level signal that is close to the noise amplitude. The formula is shown as follow:

In the above formula, the parameter unit is dB.
RMS: In this mode, all filtering and averaging processes work on the power
(the square of the amplitude) of the signal. This average type is best for measuring the true time average power of complex signals. The formula is shown as follows:

Avg State
Enables or disables the auto average function. When the auto average function is enabled, the instrument will select the best average type based on the current settings. When you select one of the average types manually, the instrument will apply the selected type, and the auto average function is disabled automatically.
4.
Limit
Sets the parameters of limit lines. After you press Preset, the limit line measurement function is disabled, but the data of the limit lines will be reserved.
The limit line data will only be deleted when the loading mode is Default. When you exit the measurement mode, the limit line data will not be deleted.
1) Test Limits
Selects whether the displayed traces are tested against the corresponding limit lines. For each displayed trace, the corresponding limit line is turned on, and a message will be displayed at the upper-left corner of the trace to indicate whether the test passes or fails.
2) Select Limit
Selects the current limit line. By default, it is Limit1.
3) Limit State
Enables or disables the display of the limit line. When the limit line is on, the measurement interface displays the limit line, and the corresponding traces are tested based on the current limit lines. Each limit line is displayed in a different color.
4) Edit Limit
When "Display State" of the limit line is set to "On", this menu is valid.
When you press this key to enter the editing menu, open the limit editing window. Then, the current limit line will be turned on. Close the peak table, and open the trace that corresponds to the limit line.
Type: Selects the type of the current limit line to be "Upper" or
"Lower". If the trace amplitude is greater than the amplitude of the upper limit line and smaller than that of the lower limit line, then the test fails.
X To CF: When "Fixed" is selected, the frequency of the current editing point will not be affected by the center frequency. When "Relative" is selected, the frequency of the current editing point is the difference between the frequency of the point and the current center frequency.
At this time, if the center frequency changes, then the position of the
2-40 RSA3000E User Guide

current editing point changes along with the center frequency.
Y To Ref: When "Fixed" is selected, the amplitude of the current editing point will not be affected by the reference level. When
"Relative" is selected, the amplitude of the current editing point is the difference between the amplitude of the point and that of the current reference level. At this time, if the reference level changes, then the position of the current editing point changes along with the reference level.
Margin State: Enables or disables the display of the margin. When you enable the display of the margin, the measurement interface displays the margin lines; when you disable the display of the margin, the margin is invalid.
Margin: Sets the margin for the current limit line.
Navigation: Selects the first line of the limit line table.
Frequency: Edits the frequency of the current point. When Rel Freq is selected, edit the frequency difference between the frequency of the current point and the center frequency.
Amplitude: Edits the amplitude of the current point. If the Rel Ampt is enabled, edit the amplitude difference between the amplitude of the current point and the reference level.
Append Point: Inserts an edit point.
Delete Point: Deletes the point that you are editing.
Build From: Sets a trace for building the limit line. The range is from
Trace1 to Trace6.
Build: Builds the limit line according to the selected trace.
Copy From: Copies the selected limit line into the current limit line.
The range is from Limit1 to Limit6.
Copy: Performs the limit line copy operation.
X Offset: Sets the frequency offset of the current limit line.
Y Offset: Sets the amplitude offset of the current limit line.
Apply Offset: Adds the X and Y offsets to each point of the current limit line, then resets the X and Y offset values to 0.
Tip: You can touch any point in the trace display window on the screen to edit the current point to be the limit line data point. You can also drag the point to adjust the position of the current edit point, that is, to change the frequency/amplitude of the current point.
5) Test Trace
Sets the trace for the current limit line test.
6) Delete Limit
Deletes the currently selected limit line. The data of the current limit line will be cleared and they will be restored to factory defaults.

Remarks:
RSA3000E offers 8 markers. Each time, one marker or one pair of markers can be turned on.
In the Marker menu, you can use the numeric keys, the knob, or the arrow keys to modify frequency or time; to view the readout of different points on the trace.
You can also use the touch screen to do the above things.
RSA3000E User Guide 2-67

Chapter 2 Functions of the Front Panel of GPSA
Selected Marker
RSA3000E provides 8 markers. By default, Marker1 is selected under "Selected
Marker". After you select a marker, you can set parameters such as the marker mode, the marker trace, and marker readout. The currently enabled marker will be marked on the trace selected under Marker Trace. The readout of the currently activated marker at the marker point will be displayed in the measurement result bar at the upper-left corner of the screen.
Marker Mode
Sets the type of the marker. The available marker modes include Position, Delta,
Fixed, and Off.
1.
Position
It is used to measure the X (Frequency or Time) and Y (Amplitude) values of a certain point on the trace. When "Position" is selected, a marker indicated by a number ("1") appears on the trace.
2.
Remarks:
If no active marker exists currently, a marker will be enabled at the center frequency of the current trace.
The readout resolution of the X-axis (frequency or time) is related to the span. To obtain a higher readout resolution, reduce the span.
Delta
It is used to measure the difference between "reference point" and "certain point on the trace": X (frequency or time) and Y (amplitude) value. When
"Delta" is selected, a pair of markers appears on the trace: Reference Marker
(marked by "X") and the Delta Marker
(m arked by "△").
Remarks:
If an active marker exists currently, then activate a reference marker at the current marker; otherwise activate both the reference marker and Delta marker at the same time at the center frequency.
When you change the position of the Delta marker, the position of the reference marker remains unchanged, but the frequency (or time) difference between the two markers will change along with it.
The frequency (or time) difference between the two markers and the amplitude difference between them are displayed in the measurement result bar at the upper-left corner of the screen.
2-68 RSA3000E User Guide

RIGOL
Application of the "Delta" Marker
It is used to measure the S/N ratio of the single spectrum signal.
Move the reference marker to the location where the signal resides, and move the Delta marker to the location where the noise resides. The amplitude displayed in the measurement results is S/N ratio.
3.
Fixed
When you select "Fixed" marker, you can directly or indirectly set the X-axis and
Y-axis values for the marker. Once specified, its position remains unchanged, and its Y-axis value does not change along with the trace. The fixed marker is generally used as the reference marker for the Delta marker. It is indicated by the sign "X".
4.
Off
Turns off the marker currently selected. Then, the marker information displayed in the screen and the functions concerning the marker will also be disabled.
Reference Marker
Sets the reference marker for the current marker. By default, the reference marker is the marker next to it.
Remarks:
Each marker can have another marker to be its reference marker.
If the current marker is a Delta marker, the measurement result of the marker will be determined by the reference marker.
Any marker cannot take itself to be the reference marker.
Marker Trace
Selects the trace that the current marker marks. It can be Trace1, Trace2, Trace3,
Trace4, Trace5, or Trace6. One marker can only mark one trace. The selected trace determines the position of the marker, the readout unit of the marker, and the final readout results.
Marker Trace Auto
Enables or disables the auto marking trace function.
Remarks:
When you enable the marker's auto marking trace function, the marker shifts from its off state to on state, and the marker's marking trace is automatically

Chapter 3 Functions of the Front Panel of
RTSA
RTSA contains the digital IF component that has a strong processing capability. In real-time mode, all signal samples are processed to produce measurement results or initiate a trigger. In most cases, like the frequency swept analysis, the real-time analysis produces scalar results, such as power or amplitude.
RTSA has the following features:
—
Seamless capture and analysis;
—
High-speed measurement;
—
Stable and consistent measurement speed;
—
Frequency mask trigger;
—
Diversified and advanced composite display
In general, the high-speed data stream in real-time mode can be used in the following two ways: to be served as the data source of composite spectrum display or be compared with the frequency mask to produce the frequency mask trigger.
This chapter describes in detail the function keys on the front panel and their associated menu functions in RTSA.
Note: The keys or menus that have the same functions as those in GPSA will not be described in this chapter. For details, refer to the relevant contents in Chapter 2.

Mask Type, the trigger mask is, by default, the one before switching the mask type.
(4) Trigger Criteria
Sets the condition that will cause the FMT trigger to occur. Both upper and lower masks use the same trigger criteria, and the trigger will occur when either mask meets the trigger criteria.
Enter: Two states are required to initiate a trigger event. The signal must be outside the mask and then passes into the mask. The trigger event occurs when the first non-violating waveform is detected.
Leave: Two states are required to initiate a trigger event. The signal must be inside the mask and then passes out of the mask. The trigger event occurs when the first non-violating waveform is detected.
Inside: Only one state is required to initiate a trigger event. The signal has at least one data point inside (above) the mask. The trigger event occurs when the instrument detects the first signal with a point violating the mask. A trigger event could occur on the first acquisition.
Outside: Only one state change is required to initiate a trigger event.
The signal has all data points outside (below) the mask. The trigger event occurs when the instrument has detected the first spectral waveform that is completely below (outside) the mask. A trigger event could occur on the first acquisition.
Enter-Leave: Three states are required to initiate a trigger event. The signal starts outside the mask and then passes into the mask. Next, the signal must pass outside the mask. The trigger event occurs at the second transition where the signal passes back out of the mask.
Leave-Enter: Three states are required to initiate a trigger event. The signal starts inside the mask and then passes out of the mask. Next,

Remarks:
The density is defined as the number of times a frequency and amplitude point is hit during an acquisition interval.
The Density view will also display a white trace. This trace shows the real-time spectrum for the latest acquisition interval. When using positive peak, negative peak, or average detectors, the white trace obtains detector data from all the data within the acquisition time; when using the Sample detector, the last FFT was used.
To display the signal status within a longer time range, you can display multiple
Density views on the screen. The latest Density view is displayed with the highest brightness. The longer the time from the latest Density view, the lower brightness of the Density view. Such display of the brightness is generally called persistence view.
The Density view is displayed combined with the persistence view. X-axis represents frequency, Y-axis represents amplitude, Z-axis represents number of hits, and T-axis represents time. This view displays four dimensional data on a two dimensional display, using color to represent Z-axis and brightness to represent T-axis.

When you select a trace that has not yet been acquired, both the trace window and Spectrogram window will remain blank until the trace is acquired. Then, once a trace is acquired in the Spectrogram window, the window will be updated for one time. The trace window will show the specified trace.
Any parameter change will clear out the spectrogram and restart an acquisition, unless in the idle state (single measurement or waiting for a trigger). The data will also be cleared on exit from the Spectrogram view.
In the Spectrogram view, zero time is the point where the first trace starts an acquisition, meaning that each subsequent trace point is at a positive time that represents when that point was gathered, relative to the start point. Each trace is time stamped as it starts, and this time is remembered for each trace. With the increase of the traces, the time difference for the successive traces get larger.

Selected Marker
RSA3000E series provides 8 markers. By default, Marker1 is selected under "Selected
Marker". After you select a marker, you can set parameters such as the marker mode and the marker trace. The currently enabled marker will be marked on the trace selected under Marker Trace. The readout of the currently activated marker at the marker point will be displayed in the measurement result bar at the upper-left corner of the screen.
Marker Mode
Sets the type of the marker. The available marker modes include Position, Delta, and
Off.
1.
Position
It is used to measure the X (Frequency) and Y (Amplitude) values of a certain point on the trace. When "Position" is selected, a marker whose name is Marker plus a marker number (such as "Marker1") appears on the trace.
2.
Remarks:
If no active marker exists currently, a marker will be enabled at the midspan frequency. If the current marker is found in the range where no trace is displayed, a marker will be enabled at the midspan frequency, and it will be displayed at the bottom of the trace display area.
The readout resolution of the X-axis is related to the span. To obtain a higher readout resolution, reduce the span.
Delta
It is used to measure the difference between "reference point" and "certain point on the trace": X (frequency) and Y (amplitude) value.
Remarks:
If an active marker exists currently, then activate a reference marker at the current marker; otherwise activate both the reference marker and Delta marker at the same time at the midspan frequency.
When you change the position of the Delta marker, the position of the reference marker remains unchanged, but the frequency difference between the two markers will change along with it.
The frequency difference between the two markers and the amplitude difference between them are displayed in the measurement result bar at the upper-left corner of the screen.
RSA3000E User Guide 4-31

Application of the "Delta" Marker
It is used to measure the S/N ratio of the single spectrum signal.
Move the reference marker to the location where the signal resides, and move the Delta marker to the location where the noise resides. The amplitude displayed in the measurement results is S/N ratio.
3.
Off
Turns off the marker currently selected. Then, the marker information displayed on the screen and the functions concerning the marker will also be disabled.
Reference Marker
Sets the reference marker for the current marker. By default, the reference marker is the marker next to it.
Remarks:
Each marker can have another marker to be its reference marker.
If the current marker is a Delta marker, the measurement result of the marker will be determined by the reference marker.
Any marker cannot take itself to be the reference marker.
Marker Trace
Selects the trace that the current marker marks. It can be Trace 1, Trace 2, and Trace
3. One marker can only mark one trace. The selected trace determines the position of the marker and the final readout results.

Remarks:
When you enable the marker line, a cross line is displayed at the amplitude point where the marker resides. The width of the horizontal line and the height of the vertical line are consistent with the length and height of the graticule in the waveform display area.
If the marker is not visible in the selected area, extend the marker line to the display area for better observation. This function is useful for the marker outside the display area. The marker extension line can better display the amplitude of the marker, making it easy for you to observe and compare.

BW
FFT Window
Sets the type of the FFT window function.
The following 4 window functions are available: Rectangular, Hanning, Gaussian, and
Flat Top.
You can select a proper filter type by referring to the following table according to the actual measurement requirements.
Characteristics Application Window
Function
Rectangular Its main lobe is relatively concentrated, but its side lobe is relatively high, with negative side lobes. This will result in high-frequency interference and leakage during transform, even
If you have a high requirement on the accuracy of the frequency readout of the main lobe, without needing to consider the accuracy of the amplitude, then the rectangular window is recommended.
Hanning
Gaussian worse, the negative spectrum. The frequency recognition accuracy is the highest, and the amplitude recognition accuracy is the lowest.
It is also called the cosine window.
Its main lobe is widened and lowered, and its side lobe is reduced significantly. In terms of leakage reduction, the Hanning window is superior to the Rectangular window.
However, the wide main lobe of the
Hanning window signifies the widened analysis bandwidth and reduced frequency resolution.
Compared with the Rectangular window, the leakage and fluctuation of the Hanning window are reduced, with more choices.
It is an exponential window. Its main lobe is wide and frequency resolution is low. It has no negative side lobe, and the attenuation of its first side lobe reaches -55dB. It is
The Hanning window is preferred under the following conditions: the signal under test has several frequency components; the spectrum is very complex; the test aim focuses more on the frequency point rather than the energy size; the signal under test is random or unknown.
For the time-varying exponential decay function, you can use the exponential window to improve the S/N ratio.
5-10 RSA3000E User Guide
Chapter 5 Functions of the Front Panel of VSA
Flat Top often used to truncate some non-periodic signals, such as the exponential decay signal.
The flat top window has few low pass band fluctuations in the frequency domain.

As there are minor errors in the amplitude, this window can be used in calibration.

(4) Trigger Criteria
Sets the condition that will cause the FMT trigger to occur. Both upper and lower masks use the same trigger criteria, and the trigger will occur when either mask meets the trigger criteria.
Enter: Two states are required to initiate a trigger event. The signal must be outside the mask and then passes into the mask. The trigger event occurs when the first non-violating waveform is detected.
Leave: Two states are required to initiate a trigger event. The signal must be inside the mask and then passes out of the mask. The trigger event occurs when the first non-violating waveform is detected.
Inside: Only one state is required to initiate a trigger event. The signal has at least one data point inside (above) the mask. The trigger event occurs when the instrument detects the first signal with a point violating the mask.
Outside: Only one state change is required to initiate a trigger event.
The signal has all data points outside (below) the mask. The trigger event occurs when the instrument has detected the first spectral waveform that is completely outside (below) the mask.
Enter-Leave: Three states are required to initiate a trigger event. The signal starts outside the mask and then passes into the mask. Next, the signal must pass outside the mask. The trigger event occurs at the second transition where the signal passes back out of the mask.
Leave-Enter: Three states are required to initiate a trigger event. The signal starts inside the mask and then passes out of the mask. Next, the signal must pass into the mask. The trigger event occurs at the second transition where the signal passes back into the mask.

Chapter 5 Functions of the Front Panel of VSA
Selected Marker
RSA3000E provides 8 markers. By default, Marker1 is selected under "Selected
Marker". After you select a marker, you can set parameters such as the marker mode and the marker trace. The currently enabled marker will be marked on the trace selected under Marker Trace. The readout of the currently activated marker at the marker point will be displayed in the measurement result bar at the upper-left corner of the screen.
Marker Mode
Sets the type of the marker. The available marker modes include Position, Delta,
Fixed, and Off.
1.
Position
It is used to measure the X (Frequency or Time) and Y (Amplitude) values of a certain point on the trace. When "Position" is selected, a marker indicated by a number ("1") appears on the trace.
2.
Remarks:
If no active marker exists currently, a marker will be enabled at the X-axis reference value of the current trace.
The readout resolution of the X-axis is related to the currently set X-axis width. To obtain a higher readout resolution, reduce the width.
Delta
It is used to measure the difference between "reference point" and "certain point on the trace": X (frequency or time) and Y (amplitude) value. When
"Delta" is selected, a pair of markers appears on the trace: Reference Marker
(marked by "X") and the Delta Marker
(m arked by "△").
Remarks:
If an active marker exists currently, then activate a reference marker at the current marker; otherwise activate both the reference marker and Delta marker at the same time at the X-axis reference value.
When you change the position of the Delta marker, the position of the reference marker remains unchanged, but the frequency (or time) difference between the two markers will change along with it.
The frequency (or time) difference between the two markers and the amplitude difference between them are displayed in the measurement result bar at the upper-left corner of the screen.
3.
Fixed
When you select "Fixed" marker, you can directly or indirectly set the X-axis and
Y-axis values for the marker. Once specified, its position remains unchanged,
5-36 RSA3000E User Guide
Chapter 5 Functions of the Front Panel of VSA
RIGOL
and its Y-axis value does not change along with the trace. The fixed marker is generally used as the reference marker for the Delta marker. It is indicated by the sign "X".
4.
Off
Turns off the marker currently selected. Then, the marker information displayed on the screen and the functions concerning the marker will also be disabled.
Reference Marker
Sets the reference marker for the current marker. By default, the reference marker is the marker next to it.
Remarks:
Each marker can have another marker to be its reference marker.
If the current marker is a Delta marker, the measurement result of the marker will be determined by the reference marker.
Any marker cannot take itself to be the reference marker.
Marker Trace
Selects the trace that the current marker marks. It can be Trace1, Trace2, Trace3, and Trace4. One marker can only mark one trace.
Marker X
Sets the frequency (when frequency-domain data source is selected) or time (when time data source is selected) of the marker to change the position of the marker on the trace. Press this key to modify the value to change the position of the marker.
Remarks:
If the marker mode of the specified marker is Position or Fixed, set the X value of the marker.
If the specified marker mode is Delta, set the X value of the delta marker relative to the reference marker.
When "Fixed" is selected for the marker mode and "I-Q" or "Constellation" is selected for the trace format, Marker X is used to determine the data points.
RSA3000E User Guide 5-37
RIGOL
Chapter 5 Functions of the Front Panel of VSA
Marker Y
When the marker type is set to "Fixed", you can press this key to set the Y value of the current marker.
Note: When "Fixed" is selected for the marker mode and "Constellation" is selected for the trace format, Marker Y is used to set the marker's in-phase component (real part) of the Y value.
Marker Y Imag
When "Fixed" is selected for the marker mode and "I-Q" or "Constellation" is selected for the trace format, Marker Y is used to set the marker's quadrature component
(imaginary part) of the Y value.
Couple Markers
Enables or disables the couple marker function.
Remarks:
When this function is enabled, moving any marker will enable other markers
(except the Fixed or Off marker) to move with it.
The fixed marker does not move along with other marker, but if the fixed marker moves, other non-fixed markers will move with it.
