Pollution Degree Description
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 r ated.
Pollution Degree 1. No pollution or only dry, 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.

RSA6100A Series & RSA5100A Series Quick Start User Manual37
Operation
Markers Display
Rectangular markers show absolute values in the readout. The readout of the selected marker appears in the upper left
corner of the display and in the Marker toolbar.
Diamond markers show delta values (relative to the reference marker). The delta readout of the selected marker appears
in the upper right corner of the display and in the Marker toolbar.
When you drag markers along a trace with either the touch screen or the mouse, the marker will seek the high points.
The marker stays within 20 trace points of the mouse position. If there are no peaks within the current range of trace
points, the marker finds the highest point.
When you attach the marker to the bitmap trace in the DPX spectrum display, the marker readout indicates the hit c ount
for pixels (maximum 65,536) along with frequency and power (see the following figure). You can position the marker
at any point in the graph.
If Option 200 is installed, markers attached to the DPX bitmap display the signal density in percent at the selected pixel,
rather then the hit count.

Real-Time Spectrum Analyzers and RSA5100A Series Real-Time Signal Analyzers Application Examples Manual.
Setting Up Triggering
The RSA6100A Series Real-Time Analyzers and RSA5100A Series Real-Time Analyzers offer real-time frequency domain
triggering (
external triggers. It uses a trigger event as a reference point in time for the seamless acquisition of the signal. This allows the
analyzer to store both pretrigger and posttrigger information.
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 a n 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.

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, you can c hose from two trigger types:
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
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.
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 it to trigger on a rising edge, Time Qualification allows you to screen rising-edge events based on how long the
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, or outside of these two values.
You can also time qualify Frequency Edge, Frequency Mask, DPX De

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

generate the trigger event. It allows you to trigger on weak signals in the presence of strong signals. This triggering is

Setting Up a DPX Density Trigger
The DPX Density trigger captures transients partially obscured by other higher-amplitude or more frequent signals. If you
can see it in the D PX bitmap, you can trigger on it. The DPX Density area measurement 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.
RSA6100A Series & RSA5100A Series Quick Start User Manual49

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 press
This action performs several tasks:

Controlling Acquisitions
When two or more displays are open, one display controls 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 fami ly controls the acquisition hardware, then the acquisition
rameters are optimized for all of the displays in that family.
