Among other applications, the channel simulator feature can be successfully used
to simulate the following scenarios:
•
Pre-echoes in a SFN or, in general, any power delay profile found in
practice in single transmitter (MFN) and multiple transmitter (SFN) networks.
•
Static channels corresponding to roof-top fixed and portable reception. In
particular, good 6-ray approximations can be generated for the F1 and P1
channels defined in Appendix B of document ETSI EN 300 744. Other
6-path profiles are those defined in Appendix K.2 of document ETSI TR
101 290.
•
Mobile channels with pure Doppler shift. An example of this is the 0 dB
echo profile proposed in Appendix K.3 of document ETSI TR 101 290.
The channel simulator may be used in conjunction with the C/N ratio generator to
evaluate the performance of a DVB-T system for a pre-defined multipath channel as a
function of the amount of additive noise present in the channel.
The wide selection of test options available in the MO-170 makes it the perfect
companion for anybody interested in checking and validating a variety of critical
aspects throughout the DVB-T system, such as in-band noise measurements, power
budgetting, receiver performance, test and verification of DVB-T measuring systems,
or simulation of real-word channel impairments.
