The Tektronix RSA6106A is a Spectrum Analyzer designed to operate in a frequency range from 9 kHz to 6.2 GHz, at 4 kHz to 20 MHz Trigger Bandwidth Range with ±0.3% Span Accuracy. The RSA6106A is a high-performance spectrum analyzer with outstanding Trigger, Capture, and Analysis characteristics. With DPX® Spectrum Processing, the user can receive instinctive insights and understanding of complicated and varying RF signals, with displays based on the frequency of occurrence. The groundbreaking DPX is meant to demonstrate transients with 10.3 μs minimum event duration. Apart from general applications, the Tektronix RSA6106A Spectrum Analyzer can also be used for the analysis of the time-variant behavior of software-defined radio systems and cognitive radio signals. It is widely employed for the characterization of hopping and pulsed systems, as well as in the debugging of RF components and modules. The RSA6106A offers 20 dBm third-order intercept (@ 2GHz), excellent high-resolution sweep speed, -151 dBm/Hz at 2 GHz displayed average noise level, and frequency mask triggering to capture any change in the frequency domain. The RSA6106A offers several analysis capabilities, such as time-correlated measurements, modulation switching, bandwidth changes, and frequency hopping. With this model, the user will be able to make multiple measurements without recapturing signals. All signals are recorded in the RSA6106A deep memory. However, different record lengths are possible at various accusation bandwidths. At 110 MHz, a record length of up to 1.7 seconds can be achieved. However, it will be around 1.46 hours at 10 kHz bandwidth.
