Testing DVB-T & DVB-H

2 Maggio 2006.

In addition to the more common test modes such as:

  • Internally generated test TS
  • Carrier blanking
  • Single carrier generation

The digital DVB-T modulator MO-170 includes other novel features:

  • Addition of white Gaussian noise with selectable C/N
  • Controlled insertion of errored bits to emulate a given BER before or after the Viterbi decoder
  • Simulation of fixed and mobile multipath channels with up to 6 taps of variable amplitude, delay, phase and Doppler frequency.
  • DVB-H is also possible as an option.

These and other features present in the MO-170 simplify the set-up of complex test systems and allows measurements over real conditions without having to spend a fortune.
