Portable spectrum analyzers track elusive signals

Staff - January 8, 2013

Outfitted with DPX waveform image-processing technology, as well as built-in mapping and signal classification, the H500 and SA2500 handheld spectrum analyzers from Tektronix scan, classify, and locate signals missed by conventional swept analysis. DPX provides a live RF view of the spectrum to allow regulators to efficiently manage and monitor spectrum in the field and hunt down elusive signals and interferers.
The field-portable analyzers offer frequency coverage from 10 kHz to 6.2 GHz, a real-time bandwidth of 20 MHz, and DANL (displayed average noise level) of –163 dBm. By color-coding events based on the rate of occurrence over thousands of spectrum captures per second, the instruments’ DPX waveform image processor provides insight into transients as brief as 125 µs on the H500 and  500 µs on the SA2500 with 100% probability of intercept.

Fully ruggedized to withstand shock and moisture, the H500 and SA2500 weigh just over 12 lbs and employ a hot-swap power system. Battery life is rated for 5 hours of continuous spectrum scanning.

The SA2500 costs $24,600; the H500 sells for $43,400.
