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 count 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.

In an instrument with Option 200, markers attached to the DPX bitmap display the signal density in percent at the selected pixel, rather then the hit count.

Setting Up Triggering

The analyzers offer real-time frequency domain triggering (option 52) and frequency edge triggering in addition to power-level triggers, li acquisition of the signal. This allows the analyzer to store both pretrigger and posttrigger information.

The analyzer has two triggering modes:

Free Run mode

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.

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 chose from two trigger types:

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

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 D ensity, and Runt trigger events. For each trigger type, the instrument ﬁnds all events that meet the basic trigger criteria, then further tests them against your time qualiﬁcation parameters.

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.

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 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:

To optimize DPX Density trigger settings for your particular signals, open the Trigger control panel. Use the controls for changing the polarity of the trigger's threshold comparison (Higher versus Lower), the Threshold value, and the size and

on of the measurement box. Use the Frequency and Amplitude settings to locate the center of the box, and set the +/-

locati values to adjust the width and height of the measurement box.

For events that are partially masked by stronger signals, you will often need to adjust the density Threshold based on density measurements of the event of interest and of the obscuring signal. For example, if the density of the background

representing only the stronger signal is 7% and the density measurement including both signals is 9%, you would

If your expected signal is a continuous tone and you want to capture events when it hops to a different frequency or drops to a lower amplitude, move the Density measurement box to surround the peak of the signal, select Lower in the Density control, and set Threshold to 100%. The instrument will trigger when the signal is absent from the measurement box.

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 family controls the acquisition hardware, then the acquisition

rameters 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.
