Portable equipment for the verification of television receivers characterized in that it is constituted by a first tunable high-frequency generator for the supply of frequencies in the high and intermediate frequency bands of television receivers; a second generator of modulation voltages in the form of synchronization pulses and of different image samples; and a third tone generator; also providing an oscillator modulated in frequency or without modulation alternatively for the supply of a frequency corresponding to the difference between the sound and image carrier eg 5 5 mc/s and a modular one to alteratively modulate the high frequency generator with one or several of the signals produced in the voltage and tone generators by coupling all these elements in a suitcase.
