Optimized inexpensive mobile Ethernet-probe of qualitative parameters DVB-T/T2 signal
For installation and adjustment of transmission DVB-T/T2 equipment in SFN mode, measurement parameters of DVB-T/T2 transmitters, coverage mobile measurement, as professional receiver for retransmission.
Extended possibilities DVB-T/T2 transmission equipment signal measurement:
- Measurement accuracy is approximated to accuracy of more expensive stationary hi-class measurement equipment and is exceeded middle-class analogs. For example, MER measurement is up to 39 dB (in analogs – up to 34 dB).
- Shoulder distance measurement up to 45 dB measurement (not available in analogs). It’s important when use transmission equipment with channel filter with critical mask.
- Spectral irregularity measurement in RF frequency band (not available in analogs).
- Crest-factor (CCDF) measurement (not available in analogs).
- Coverage measurement (optional).
- Pulse response measurement.
- Signal demodulation from RF-input and decoding in MPEG-2, MPEG-4 from RF-input and ASI-input with possibility to view TV-programs on PC.
Basic technical characteristics:
- Real-time demodulation and measurement DVB-T/T2 signal parameters;
