This appendix contains the operating instructions for the following option belonging to the COFDM modulator: MO-170
OP-170-E
White noise generator for C/N testing.
Fixed and portable channel simulation in SFN/MFN networks.
The MO-170 is a versatile professional DVB-T modulator providing a complete test suite, which can be used to perform measurements on the DVB-T signal chain at different points. In addition to the test modes typically found in other equipment, the MO-170 includes other novel features, such as the addition of white Gaussian noise with selectable C/N ratio and the simulation of fixed and mobile multipath channels with up to 6 taps of variable amplitude, delay, phase and Doppler frequency.
The MO-170 offers the possibility of simulating dynamic and static multipath channels with five echoes (plus the main path).
