A measure of the contaminants that could occur in the environment around and within a product. Typically the internal environment inside a product is considered to be the same as the external. Products should be used only in the environment for which they are rated.

Pollution Degree 1. No pollution or only d ry, nonconductive pollution occurs. Products in this category are generally encapsulated, hermetically sealed, or located in clean rooms.

Pollution Degree 2. Normally only dry, nonconductive pollution occurs. Occasionally a temporary conductivity that is caused by condensation must be expected. This location is a typical ofﬁce/home environment. Temporary condensation occurs only when the product is out of service.

Pollution Degree 3. Conductive pollution, or dry, nonconductive pollution that becomes conductive due to condensation. These are sheltered locations where neither temperature nor humidity is controlled. The area is protected from direct sunshine, rain, or direct wind.

Pollution Degree 4. Pollution that generates persistent conductivity through conductive dust, rain, or snow. Typical outdoor locations.

Basic Concepts

Real Time Analyzers

Tektronix real-time analyzers have a frequency mask trigger. The frequency mask trigger allows you to set up a spectral mask to captu acquiring, and then capture precisely the intermittent RF event of interest.

DPX™ technology allows you to view the RF signal as a live display. You can view very short transient signals, multilevel signals, and time-varying events. You a lso have the ability to m easure and trigger on signal density values in the DPX display.

The analyzers allow you to view the captured signals in a wide variety of time-correlated displays. This is useful for device troublesho the DPX display has a unique method for processing, storing, and displaying the data.

Measurement Displays

The analyzer window can show one or any combination of general purpose and application-speciﬁc displays.

This example shows a DPX Spectrum Split display. A DPXogram display appears on the top and a DPX Spectrum display appears on the bottom.

The acquisition data source can be a l ive acquisition or a saved acquisition data ﬁle. The sharing of acquisition data between displays allows you to view the same data in multiple ways. For example, you can display a power versus frequency (spectrum) display and a spectrogram diagram at the same time. Because the data source is shared among the different displays, the displays are correlated. That is, a point or set of points within one display is associated with a point or set of points in every other display in the application window.

Operation

Navigating Displays

The analyzers use multiple displays to keep operations simple, and yet provide advanced functionality when needed. Some of the display categories include:

General Signal Viewing displays. These displays show graphs for basic signal parameters such as amplitude, phase, and frequency plotted against frequency or time. Examples of these displays include: Spectrum, DPX, Spectrogram, Time Overview, and Phase vs Time.

Analog Modulation. These displays show graphs and measurements for Analog Modulation, Frequency Modulation, and Phase Modulation.

General Purpose Digital Modulation displays. Available with Option 21. These displays show the results of demodulating signals and analyzing them in multiple domains. Examples of these displays include: Constellation, EVM vs Time, Eye, Symbol Table, and Trellis diagrams.

RF Measurements displays. Available with Option 11. These displays show the results of automated measurements on RF signals. Examples of these displays include: ACPR, MCPR, Phase Noise, and CCDF.

OFDM Analysis. Available with Option 22. These displays provide OFDM analysis for WLAN 802.11a/j/g and WiMax

802.16-2004 signals.

Pulsed RF displays. Available with O ption 20. These displays show the results of advanced analysis for pulsed RF signals. Examples of these displays include: Pulse Statistics, Pulse Table, and Pulse Trace.

Audio Analysis. Available with Option 10. These displays measure basic time- and frequency-domain parameters of analog audio signals modulated on a carrier (AM, FM and PM modulation) or unmodulated (non-carrier) audio signals (Direct).

WLAN Analysis. Available with Options 23, 24, and 25. Each of these options provide OFDM analysis of WLAN802.11 standards. All three options combined provide analysis for WLAN802.11a/b/g/j/p/n/ac signals.

Advanced Techniques

This section contains advanced operating techniques. For examples of practical applications, see the SPECMONB Series Real-Time Spectrum Analyzers Application Examples M anual.

Setting Up Triggering

The analyzers offer real-time frequency domain triggering and frequency edge triggering in addition to power-level triggers, line trigger of the signal. This allows the analyzer to store both pretrigger and posttrigger information.

To set up triggering, ﬁrst select the Event (source and trigger type). Next, continue to set other optional trigger settings, such as Time Qualiﬁed aspects and deﬁne speciﬁc actions to be taken upon recognition of a trigger event (such as Save data, save picture, etc ).

The analyzer has two triggering m odes:

Free Run mode. In Free run mode, the instrument initiates acquisitions without considering any trigger conditions. It

is a fast and easy way to see the signals. Free Run is usually adequate for the Spectrum display unless you need to specify a particular time at which to collect the data record.

Triggered mode. In Triggered mode, the instrument initiates an acquisition when a trigger event is recognized. The

conditions that deﬁne a trigger event depend on the selected trigger source. There are several source selections available for choosing the signal to monitor for a trigger event.

, runt trigger, and external triggers. It uses a trigger event as a reference point in time for the seamless acquisition

Operation

Once you select the Triggered mode, you must select the source. The trigger sources are:

RF Input

Trig In

Trig2In

Gated

Line

Once you select the trigger source, you can set additional parameters to specify the trigger event. If you specify the RF Input as the trigger source, y ou can chose from the following trigger types:

Power Triggering. Power triggering triggers the instrument on time-domain signal characteristics. The incoming data is

compared to a user-selected level in dBm. You can select the time-domain bandwidth and trigger on the rising o r falling edge.

Frequency Edge Triggering. Frequency Edge triggering triggers the instrument on time-domain signal characteristics.

The incoming data is compared to a user-selected level in Hertz. Frequency edge trigger is similar to Power triggering, except you also need to set a power threshold to avoid triggering on the apparent frequency ﬂuctuations that occur at low amplitude. You can select the time-domain bandwidth and trigger on the rising or falling edge.

Frequency Mask Triggering. Frequency Mask Triggering allows you to trigger the instrument when a signal in the

frequency domain violates the mask. You can draw a mask to deﬁne the conditions within the real-time bandwidth that will generate the trigger event. It allows you to trigger on weak signals in the presence of strong signals. This triggering is also useful for capturing intermittent signals.

DPX Density Triggering. This trigger type enables the instrument to capture any signal you can see in the DPX display,

including difﬁcult to see signals hiding beneath other signals that have a higher amplitude or a greater repetition rate. Using

Operation

the Trigger On This™ feature, you can draw a box around the area of interest in the graph, set a Density threshold, and the instrument

will trigger when the measured Density exceeds your threshold.

Runt Triggering. Runt triggering deﬁnes a trigger event based on a pulse amplitude that crosses one threshold but fails

to cross a second threshold before recrossing the ﬁrst.

In addition to deﬁning the trigger event, you can deﬁne the following parameters by selecting the Advanced tab in the Trigger control panel:

Position and Delay parameters that deﬁne where a trigger occurs within the acquired data record and whether to delay the trigger for a set amount of time.

Whether a single event can trigger an entire sweep, or each segment of the sweep requires a new trigger event in swept acquisition mode.

Time Qualiﬁed Triggering. Time Qualiﬁed triggers allow you to trigger the instrument based on when signal transitions

occur in time. You can apply time qualiﬁcation to the basic trigger types. For example, if you select the Power type and conﬁgure i signal stays high after it exceeds the trigger threshold. You may wish to trigger only on pulses that last longer than a speciﬁed time or shorter than a speciﬁed time. You can set Time Qualiﬁed to accept only pulse widths between two speciﬁed values, o

The DPX Density trigger enables you to capture transient events that may be partially obscured by other higher-amplitude or more freq is used to select the region of interest in the display and to measure its current density. You set a density threshold, and the instrument triggers when the density measurement exceeds your threshold.

The quickest way to set up a DPX Density trigger is to use a mouse and right-click on a signal of interest in the DPX graph, or p This action performs several tasks:

Controlling Acquisitions

When two or more displays are open, one display c ontrols the acquisition system. The acquisition requirements for the selected display set the acquisition hardware parameters. While the acquisition parameters are optimized for the selected display, they might not be ideal for other displays. In this case, the other displays might be unable to maintain optimum performance and consequently might be unable to produce results. (This also happens when you analyze recalled data: measurements attempt to deliver results, but may not be able to comply with all their settings.)

You can specify which display controls the hardware acquisition parameters by clicking anywhere in that display. When there are multiple displays, the highlighted display controls the hardware acquisition parameters.

In this example, there are two displays, a Spectrum display and a DPX Spectrum display. The highlighted title bar on the Spectrum display indicates that it is the selected display.

The check mark indicator in the upper left corner of the display indicates that acquisition hardware is optimized for the Spectrum display.

Some displays do not control the acquisition hardware. These displays just show the captured data. Some displays share the same parameters. If any of one of these displays in such a family controls the acquisition hardware, then the acquisition parameters are optimized for all of the displays in that family.

8. Specify whether table corrections are applied to all acquired data or only to traces in the Spectrum, Spectrogram, Spurious and Amplitude vs Time displays.

Corrections applied to data are performed in real time using the digital ﬁlter capabilities of the instrument. While this has the advantage of correcting the data for use in all measurements, digital ﬁltering is limited in its ability to apply corrections that change rapidly in amplitude over small frequency ranges, as may occur when switching between two antennas. When this happens, the ﬁlters may result in an amplitude correction that appears to ring in its response, resulting in poorly corrected data. For that reason, the instrument offers trace-only correction for spectrograms, spectrum, spurious, and amplitude vs. time displays. These trace corrections are similar to those applied in traditional spectrum analyzers, and should be used when discontinuities occur in the amplitude/frequency correction table.
