Audio parameters of a Analog TV Transmitter system. It should also have the up gradation
facility for measuring digital parameters.
2. Features and Measurements required:
2.1 Analog Audio measurement functions: Instrument must have the facility to measure the
following Analog audio parameters of an Analog TV Transmitter(i) Level
(ii) Cross talk
(iii) Frequency
(iv) Total Harmonic distortion
(v) Noise
(vi) Wow and Flutter
(vii) Drift
(viii) Inter modulation Distortion
(ix) Narrow band selective level
(x) Spectral FFT analysis
2.2 Digital Audio measurement functions: Instrument must have the up gradation facility to
measure the following Digital audio parameters of a Digital TV Transmitter (DVB-T2
Standard):
(i) Carrier Level
(ii) Sampling Frequency
(iii) Jitter Analysis
(iv) Peak level
(v) Bit statistics
(vi) Status Analysis
