Interference Troubleshooting

has Never Been so Easy

The H500 and SA2500 will quickly scan the RF environment, classify

the known signals, and help you locate the unknown signals with their

field-proven signal hunting tools. Featuring real-time DPX™ Live RF

spectrum display technology, the H500 and SA2500 offer practical solutions

for discovering transient events that slip past conventional spectrum

analyzers. With field-ready, rugged hardware featuring outstanding

displayed average noise level (DANL), spurious free dynamic range

(SFDR), phase noise, and easy LAN networking capability in a handheld

unit, the H500 and SA2500 are a great choice for general-purpose spectrum

measurements and ideal signal-hunting tools.

Evolving digital RF communication standards pose an unprecedented

challenge to the surveillance and security community. Identification of

unknown signals and determining their precise location has traditionally

been accomplished using a combination of lab-grade spectrum analyzers,

handheld spectrum analyzers, oscilloscopes, and offline analysis

capabilities using PCs. When lab equipment is used in the field, several

limitations appear. Such instruments are not meant for field use, can

be easily damaged, are not portable, and require AC power. Signal

classification using these systems often requires a lot of prior knowledge

about these signals, particularly when they are digital. With such systems

the unknown signals can be difficult or impossible to identify.

Scan

By scanning the RF spectrum users can spot which signal emitters

are in the area. Signals with significant power are usually candidates

for further analysis, as are signals that are present infrequently. By

color-coding events based on the rate of occurrence, the DPX™ Live RF

spectrum display provides unparalleled insight into the behavior of signals.

Performing 10,000 spectrum updates per second, transients as brief as

DPX Spectrum Mask captures and logs spectrum violations with options of warning alarm,

pausing test, export screen, and result save

125 μs can be “frozen” in the frequency domain. This offers tremendous

improvement over swept analysis techniques.

Signals that are present in the spectrum today but were not there yesterday

are of particular interest. Reference signals can be stored and deviations

from this reference can be quickly identified using the trace math feature.

The H500 and SA2500 make analysis easier by quickly logging signals that

are weak, bursting, hopping, time multiplexed, or intentionally random. It

takes advantage of the FFT-based spectrum analysis capability to allow

users to see the true shape of the signal, even when it is bursting. Masks

canbeautomatically created from traces captured earlier. You can compare

this mask to the current trace and if a mask violation occurs, the trace is

logged. Finally, when the spectrogram is paused, you can scroll through the

spectrogram’s time axis and view the results.
