Siglent SSA5083A — 9 kHz to 13.6 GHz microwave spectrum analyzer
The Siglent SSA5083A is a flagship microwave spectrum analyzer covering 9 kHz to 13.6 GHz through a 2.92 mm input. With -105 dBc/Hz phase noise, a -165 dBm/Hz noise floor and a standard 20 dB preamplifier, it resolves close-in signals and weak spurs with ease. A 12.1-inch multi-touch display drives a full measurement platform — with optional real-time, modulation, Bluetooth, noise-figure and phase-noise analysis — and it is field-upgradeable to the full 26.5 GHz.
Product overview
The SSA5083A is Siglent's flagship microwave spectrum analyzer, covering 9 kHz to 13.6 GHz through a 2.92 mm input. With −105 dBc/Hz phase noise, a −165 dBm/Hz displayed average noise level and a standard 20 dB preamplifier, it resolves close-in signals and weak spurs that lesser analyzers miss — the basis for reliable signal-purity and spectral measurement. The SSA5083A is field-upgradeable to the full 26.5 GHz range (F5).
A large 12.1-inch multi-touch display with HDMI output drives a full measurement platform: optional 25/40 MHz real-time analysis, analog & digital modulation, Bluetooth, noise figure, phase noise, EMC and advanced measurements all activate as licences, so the SSA5083A grows with the most demanding RF and microwave work.
Built for the bench and for automation, the SSA5083A offers a +23 dBm maximum input, a −170 dBm reference level, RBW from 1 Hz to 10 MHz and swept or FFT sweep, with LAN, USB and an optional GPIB interface plus a full SCPI command set. An optional high-accuracy OCXO reference and a 7.2 µs 100% probability of intercept in real-time mode round out a genuinely capable microwave analyzer for 5G, radar, satellite, aerospace and advanced R&D.

Bluetooth Analysis
Bluetooth is widely used in various devices and application scenarios as a wireless communication technology. The measurement application follows the Bluetooth® RF test specification issued by Bluetooth SIG to calculate the measurement results, and automatically detects the protocol version of the signal for Bluetooth BR/EDR/LE with one-click measurements to help you design, evaluate and manufacture Bluetooth devices with confidence. Together with the new SigIQPro signal generation software and a SSG5000X-V generator, it forms an economical and efficient SIGLENT Bluetooth signal generation and signal analysis solution, accelerating the process from signal generation to data to evaluation. The SSA5000A is helpful for users to troubleshoot flexibly in the laboratory and optimize RF design easily and quickly.
Phase Noise Measurement
A stable frequency source is a common need for many electronic devices and most RF equipment. Phase noise can be used to characterize the short-term frequency stability of these frequency sources. Siglent’s SSA5000A Spectrum analyzers now provide a one-button phase noise measurement. The SSA5000A features lower Display Average Noise Level (DANL) and phase noise ensuring the accuracy of your tests. The smaller resolution bandwidth avoids measuring both carrier power and noise power together, and the measurement results are automatically calculated and graphed. The use of a logarithmic scale for the horizontal coordinate gives both a wider frequency range and finer resolution when close to the carrier – smaller offsets tend to reflect the quality of the signal better than phase noise at larger frequency offsets.

Noise Figure Measurement
Accurate measurement of noise figure is crucial in product development and manufacturing. In the field of research and development, high test accuracy can ensure high repeatability between design simulation and real measurement and help to find the noise sources that are not considered in the simulation process. In the field of production and manufacturing, higher test accuracy means that the index margin can be set smaller when setting and verifying the technical index of the device. The higher the technical index of the final product, the more competitive it will be in the market. Quantifying those unknowns depends on flexible tools that provide accurate, reliable results. The noise figure measurement function of SIGLENT SSA5000A provides engineers with a simple tool, which can quickly and effectively measure the noise figure with high accuracy. Engineers can characterize noise figure and gain of connectorized devices and system blocks with graph, meter, and table layouts, and support the measurement of noise factor, Y-factor, effective temperature, and hot/cold power density.
