Tektronix RSA5126B Real Time Spectrum Analyzer

Overview

The Tektronix RSA5126B 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.

Key Features

• Real-time processing up to 3,125,000 spectrums per second with 100% probability of intercept for signals as brief as 0.434 μs
• Swept DPX spectrum display with advanced processing including gap-free DPX spectrograms and real-time amplitude, frequency, or phase analysis
• Frequency range: 1 Hz to 26.5 GHz with multiple acquisition bandwidths (25, 40, 85, 125, or 165 MHz)
• Spurious-free dynamic range of 80 dB over entire acquisition bandwidth with HD options
• Wideband preselection filter providing image-free measurements across full analysis bandwidth
• DPX density trigger to capture single occurrences as brief as 0.434 μs and distinguish between continuous and infrequent events
• Advanced time-qualified, runt, and frequency-edge triggers operating on signals as brief as 20 ns
• Comprehensive measurements: channel power, ACLR, CCDF, OBW/EBW, spur search, EMI detectors, AM/FM/PM modulation analysis
• Optional modulation analysis including Phase Noise, pulse measurements, APCO P25 compliance testing, WLAN analysis, Bluetooth analysis, LTE measurements, and EMC/EMI pre-compliance
• Continuous acquisition capability: more than 5 seconds at 165 MHz bandwidth
