Overview
R&S EFA-T, even the basic version, features a wide range of innovative measurement functions, allowing comprehensive, indepth signal analysis. As well as easuring general parameters (Fig. 1) such as bit error ratio (BER), more thorough analysis includes:
- I/Q constellation diagrams (Fig. 2): the number of symbols to be displayed is user-selectable, range: 1 to 999 999 symbols
- Calculation of I/Q parameters: amplitude imbalance, quadrature offset and carrier suppression, phase jitter, SNR and MER (modulation error ratio) (Fig. 3)
- Frequency domain displays, e.g. MER(f), I|Q(f) or interferer (Figs 4, 5 and 6)
- Amplitude, phase and group-delay/ frequency response displays (Fig. 7)
- Amplitude spectrum, including automatic shoulder attenuation measurement to ETR290 (Fig. 8)
- Long-term monitoring of dedicated parameters through the history function (Fig. 9), monitoring time is selectable from 60 seconds to 1000 days
- Linearity analysis from amplitude distribution histogram or CCDF (Figs 10 and 11)
- Received impulse response within the guard interval - including zoom function (Fig. 12)
