Using equipment: communication means. SUMMARY OF THE INVENTION: The device contains a test chart 1, the transmitter of electromagnetic radiation and interference in the test signal pulses, a receiver 3, a test signal generator 4, the delay unit 5 is controlled by the correlator 6, the control unit 7, two block memory 8 and 9, unit phase-locked loop 10, subtractor 11, a pulse selector lines and fields 12, dividing unit 13, an amplitude selector 14 and the indicator 15. The measuring accuracy of the measurement is improved by employing the correlation processing, provide a compensation of interference from the mouth oystva sweep investigated apparatus via the memory blocks and the block and subtracting You are a possible administration of the test signal in the video portion of a television receiving apparatus using galvanic connection to the input test signal generator or a video path of a television camera optical path using the test chart. 1 2-3-6-9-11-13-15, 7-5-6, 7-4, 7-8. 06.08.11, 8-7, 7-10, 14-12-10,7-13,7-9. 1 yl.
