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.
Applications include: broadcast monitoring, evaluation, cellular site evaluation, IoT, WiFi, Bluetooth, R&D, education, production test & maintenance.
The Siglent SSA3075X-R is a powerful and flexible tool for RF signal and network analysis. With a frequency range up to 7.5 GHz, this analyzer delivers reliable automatic measurements and multiple modes of operation, with other optional functions also offered pre-compliance, research and development, education, production, and maintenance.
