Saelig Company Inc. has introduced the SIGLENT SSA3000X-R Real-Time Spectrum Analyzers (RTSA), which are powerful and flexible tools for complex radio frequency (RF) spectrum and signal analysis. With a capability of 40 MHz analysis bandwidth and 7.2 μs 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 wide band digital

The SSA3050X-R model has a frequency range of 9 kHz to 5.0 GHz, while the SSA3075X-R has a range of 9 kHz to 7.5 GHz. The built-in tracking generators operate from 100 kHz to 5.0 GHz and 100 kHz to 7.5 GHz respectively, and a preamplifier is included as standard. Control is made easy with a 10.1 in multi-touch screen, with an external mouse and keyboard also supported. 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 uses overlapping Fast Fourier Transforms (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 voltage standing wave ratio 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, internet of things, Wi-Fi, Bluetooth, R&D, education, and production test and maintenance.
