Overview
The new test receiver, even the basic version, features a wide range of innovative measurement functions, allowing comprehensive, in-depth signal analysis. In addition to measuring general parameters (Fig. 1) such as bit error ratio (BER), more thorough analysis includes:
- I/Q constellation diagrams (Fig. 2) with user-selectable number of symbols to be displayed, range: 1 to 999 999 999 symbols
- Frequency spectrum, including automatic shoulder attenuation measurement to FCC recommendation (Fig. 3)
- Complex channel transmission function (Fig. 4)
- Received echo signals (ghost pattern, Fig. 5)
- Histogram I (Fig. 6) with user-selectable number of symbols to be dis-played, range: 1 to 999 999 999 symbols
- Modulation error ratio (MER), error vector magnitude (EVM), phase jitter and signal-to-noise ratio (Fig. 7)
- Linearity analysis from amplitude distribution histogram and CCDF referred to the RF signal (Fig. 8 and Fig. 9)
- History function: long-term monitoring of transmission parameters (Fig. 10)
- Alarm monitoring window (Fig. 11)
- and alarm statistics (Fig. 12)
- Permanent MPEG2 transport stream demodulation (independent from the selected measurement task)
- Integrated noise generator
