The SSA3075X-R extends the Siglent SSA3000X series to add real-time spectrum analysis capabilities for intermittent and frequency-hopping signals used in commercial communications and 5G applications.
Saelig Company, Inc. has introduced the SIGLENT SSA3000X-R Real-Time Spectrum Analyzers (RTSA) which are powerful and flexible tools for complex RF spectrum and signal analysis. With a capability of 40MHz analysis bandwidth and 7.2μs 100% probability of intercept (POI), the analyzers can provide multi-dimensional data displays, advanced triggering, and RF data capturing, to assist with modern RF spectrum challenges such as frequency hopping, channel conflicts, spectrum interference, etc. These RTSAs also contain a standard tracking generator for network analysis, optional wideband digital modulation analysis, and EMI measurement. The SSA3050X-R model has a frequency range of 9kHz to 5.0GHz, while the SSA3075X-R has a range of 9kHz to 7.5GHz. The built-in tracking generators operate from 100kHz to 5.0GHz and 100kHz to 7.5GHz respectively, and a preamplifier is included as standard. Control is made easy with a 10.1” multi-touch screen, with an external mouse and keyboard also supported. A remote control is also possible via an attached PC or web browser.
Many real-world signals such as modulated communications signals, spurious interference, and pulsed or frequency-hopping transmissions are sporadic, non-recurring, or even random. Using traditional spectrum analyzers, which steadily sweep through the active spectrum, these signals can easily be missed. Real-time spectrum analysis (RTSA) uses overlapping FFTs and high-speed memory to provide a 100% probability of intercept to detect even intermittent signals. Real-time bandwidth, the maximum frequency span of overlapping FFTs, is a critical parameter for an RTSA to allow detailed analysis of a signal’s spectrum.
The SSA3000X-R analyzers can also perform in a swept or a real-time mode. A modulation analysis mode is also available for AM/FM, ASK/FSK/PSK/MSK/QAM vector signal modulation analysis and EVM evaluation, as well as data recording to a PC. An EMI measurement mode allows for pre-compliance and other RF testing. Reflection measurement VSWR and return loss measurement with Q value calculation can be accomplished using an external reflection bridge or coupler.
