Frequency Domain Analysis:
The FSIQ7 excels in accurately measuring intermodulation and harmonics. Its high third-order intercept and ultra-low noise floor yield a dynamic range exceeding 110 dB, ensuring reliable results even for sophisticated measurements. It is optimized for adjacent-channel power ratio (ACPR) measurements across mobile radio systems, particularly WCDMA, where a maximum ACPR of 75 dB can be attained at input levels as low as -12 dBm. With an RMS detector supporting all bandwidths up to 10 MHz, precise measurements of channel and adjacent-channel power can be seamlessly obtained regardless of signal statistics.
Time Domain Analysis:
The FSIQ7 is designed for modern TDMA systems, featuring advanced burst analysis capabilities with gate functions and triggered delay. Its quick 1 µs sweep time, combined with a range of bandwidth options up to 10 MHz, minimizes instrument impact on measurements. Efficient marker functions and editable gated sweeps provide options for conducting RMS, average, and peak measurements over any desired time frame.
Modulation Domain Analysis:
In the modulation domain, the FSIQ7’s integrated vector signal analyzer is versatile for both digital and analog modulations. Users can access settings for 18 different mobile radio standards—including GSM, NADC, IS95, and WCDMA—streamlining the measurement process and enhancing reliability. Results can be presented through vector and constellation diagrams, I/Q signal displays, and detailed tables that include demodulated bit sequences. Key metrics such as error vector magnitude (EVM), phase and frequency errors, and I/Q offsets are provided as numeric values for clarity. The FSIQ7 also offers a comprehensive suite of 13 digital demodulators suitable for various modulation techniques, ensuring compatibility with user-defined systems and enabling precise, long-term measurements.
