Saelig Introduces 4th Generation AIM-TTi PSA2704RT 2.7GHz Spectrum Analyzers

ROCHESTER, N.Y. - July 15, 2026 - PRLog -- Saelig Company, Inc. has announced the release of the AIM TTi PSA Series 4 Handheld Spectrum Analyzers. A significant technical leap forward for the popular PSA family, this next-generation series introduces real-time signal capture alongside classic swept and fast-swept FFT modes. The Series 4 allows field engineers and bench technicians to instantly and reliably identify transient, intermittent, and frequency-hopping signals that escape conventional swept analyzers.

Never miss a transient event with the Series 4RT - up to 80,000 FFTs per second for true real time performance.  Offering a 10.8MHz real-time bandwidth and a frequency range of up to 2.7GHz, the RT analyzer boasts a 100% Probability of Intercept (POI) for transient signals lasting as briefly as 37.5µs. This capability provides a gap-free, continuous observation window of the spectrum.

To assist operators in translating massive amounts of live RF data into actionable intelligence, the Series 4 features a comprehensive suite of highly visual display formats. Users can dynamically toggle between full, combined, or split-screen layouts incorporating Live Traces, Waterfall plots, and 3D Heatmaps. For complex signal tracking, the system supports advanced multi-mode zero-span configurations, allowing concurrent rendering of amplitude versus time, amplitude depth versus time, and frequency deviation versus time. These visualization modes are augmented by AM/FM audio demodulation, seven distinct detector modes, and programmable Frequency Mask Triggering to automatically capture and log elusive spectral anomalies.

Engineered for field mobility and harsh operational environments, the PSA Series 4 delivers exceptional analytical precision within a compact (7.6" x 3.6" x 1.9"), ultra-lightweight enclosure weighing just 1.28lbs. Despite its portable footprint, the device achieves benchtop performance, with a Displayed Average Noise Level (DANL) as low as -131dBm and a 1.4:1 typical VSWR, granting engineers an expanded dynamic measurement range from -120dBm up to +17dBm.

The user interface revolves around a bright, 4.3" backlit color touchscreen driven by an optimized menu architecture that supports effortless one-handed operation. Typical applications include: interference analysis, antenna alignment and optimization, signal-strength mapping, covert transmitter detection, spurious-emission checks, EMC site and pre-compliance survey, WiFi setups, etc.

Made by AIM-TTi, one of Europe's leading test equipment manufacturers, Series 4 Spectrum Analyzers are available now from their USA technical distributor Saelig Company, Inc. Fairport, NY.  For  additional information, please contact Saelig at 1-888-7SAELIG
