Description
Overview
The Tektronix RSA5126A is a real-time spectrum analyzer providing comprehensive signal analysis from 1 Hz to 26.5 GHz. It combines spectrum analysis, wideband vector signal analysis, and real-time signal processing in a single instrument, enabling rapid discovery and characterization of transient and frequency-agile RF signals with minimal signal duration detection.
Key Features
- Real-time processing up to 292,000 frequency transforms per second with 100% probability of intercept for signals as brief as 0.434 μs
- DPX spectrum display with live color visualization of transient signal behavior in the frequency domain
- Frequency range: 1 Hz to 26.5 GHz with multiple acquisition bandwidths (25, 40, 85, 125, or 165 MHz)
- Wideband preselection filter for image-free measurements across entire analysis bandwidth
- Complete signal statistics measurements including Channel Power, ACLR, CCDF, Occupied Bandwidth, AM/FM/PM, and Spurious
- Phase Noise and General Purpose Modulation Analysis measurement options
- Advanced triggering: time-qualified power, runt, density, frequency, and frequency mask triggers
- Gap-free spectral recording and replay of up to 60,000 spectral traces (with Option 200)
- Swept DPX spectrum processing enabling broadband transient capture over entire frequency range
Applications
- Wideband radar and pulsed RF signal analysis
- Frequency-agile communications monitoring
- Broadband satellite and microwave backhaul testing
- Transient signal discovery and analysis
- Design validation and troubleshooting
- Research and educational applications
