- Rigol integrates two complementary software tools to its real-time spectrum analyzers of the RSA5000 range: the Vector Signal Analysis Software VSA and EMI Analysis Software applications.
Rigol offers the Vector Signal Analysis Software VSA dedicated to its RSA5000 spectrum analyzers with touch screen. It is a software application for demodulation and vector analysis of the signal in order to identify possible problems occurring in the time and frequency domains or concerning modulation.
Various functions such as RF envelope analysis of the I/Q waveform and digital modulation analysis are proposed. The FMT trigger is based on the signal processing technology called Ultra Real developed by the Chinese manufacturer for modulation acquisition and analysis. It allows measurements and signal analysis according to communication and wireless connection standards as well as binary error rate (BER) testing for known signal sequences.
This software application supports different types of modulation: FSK2, FSK4, FSK8, MSK, BPSK, QPSK, OQPSK, DQPSK, 8PSK, π/4-DQPSK, π/8-D8PSK, D8PSK, QAM16, QAM32, QAM64, ASK2, and ASK4. The results of the analyses can be displayed in various forms: signal amplitude in time domain, spectrum, eye diagram, constellation and vector diagram, error vector magnitude, quadrature error, amplitude error, and phase error.
Rigol also offers the EMI Analysis Software application for the analysis of electromagnetic interference (EMI) by its RSA5000 spectrum analyzer, which allows measurement reports to be made according to CISPR 16-1-1-1-1 standard without the need for additional PC software. It has built-in CISPR compliant bandwidths, detectors and band presets. The software allows automatic testing against regulatory limit values with user-defined margins and provides amplitude correction for antennas, LISNs (Line Impedance Stabilization Network), cables and preamps.
Both software applications are already installed in the newly launched RSA5000 spectrum analyzers. However, existing instruments can benefit from it through a software upgrade.
