RIGOL Technologies introduces the new RSA5000 real-time spectrum analyzers to complement the DSA800-TG family of low-cost spectrum analyzers. The devices are based on the new Rigol-developed Ultra-Real technology as a complete platform, which also allows to perform real-time measurements. The RSA5000 series features a compact, elegant design, touch-screen operation and a wide range of applications, and can also be used as a scalar network analyzer thanks to the additional 3.2 / 6.5 GHz tracking generator. RIGOL's RSA50xx-TG real-time spectrum analyzer provides a cost-effective alternative for users with demanding analysis tasks and limited budgets at the same time. This fully featured instrument features fully digital Intermediate Frequency (IF) technology for accurate and high-resolution measurements from 9 kHz to 3.2 GHz and 6.5 GHz respectively.
The modular RSA5000 series includes the functions:
- RTSA – Real-time spectrum analyzer up to a maximum bandwidth of 40 MHz
- GPSA – Spectrum Analyzer with outstanding performance
- EMI – Pre-compliance tests according to CISPR specifications (with the software S1210)
- VSA – Digital Demodulation (option planned in Q2 / 2018)
The real-time bandwidth is 25 MHz by default and can be optionally extended to 40 MHz. Thus, the device can be flexibly adapted to customer requirements. Due to the very fast FFT calculation, the device can achieve a 100% detection probability with correct amplitude (POI – Probability of Intercept) of 7.45 μs. The device can still detect smallest signals up to 25 ns. Thus, it is possible to detect signals that cannot be measured with a normal spectrum analyzer.
Due to the resulting high information content, different measurements such as a density representation of the frequency, a spectrogram or time range can be displayed, even simultaneously. The versatile frequency mask trigger (FMT) can also detect difficult signals. Using different filter types and six different RBW widths, the device can be optimally adjusted to the respective application. Further details include the FFT rate of up to 146.484 FFT/s, an integrated FMT and power trigger as well as interfaces for USB, LAN, HDMI and GPIB (optional).
A spectrum analyzer is used to represent signal amplitudes as a function of frequency and provides the user with a choice of IF filters to reduce the displayed bandwidth and isolate a dedicated signal from the surrounding noise. The RSA5000 Spectrum Analyzer's digital IF technology significantly reduces the amplitude variations over time and frequency compared to analog filters. The effective measuring speed is more than twice as fast as with the DSA800 series.
With add-on options such as the EMI filter & quasi-peak kit, preamp, and expandable measurement capabilities, the RSA5065-TG is ideal for pre-compliance testing of assemblies, devices, and components while capturing rapidly changing signals. This means that the customer can already carry out very cost-effective pre-tests in-house before the products are passed on to the usually very cost-intensive EMC final test to external, certified test laboratories. During product development, in-house pre-tests ensure that the product meets EU standards for EMC, which are mandatory in all EU countries and other European countries.
The RSA5000 has a 10.1″ capacitive multi-touch display with 800 x 480 pixel resolution and receives its input signals via a 50 Ω Type N socket. Connections to a PC are possible via Ethernet LAN and USB as well as optionally via GPIB. The optional tracking generator of the RSA5000-TG provides -40 to 0 dBm output power with ± 3 dB output flatness from 1 MHz to 6.5 GHz for VSWR measurements or scalar analysis.
