The device for setting TVs "PNT-59" was produced since 1959. It is intended for visual viewing of the frequency response of radio television devices and is a combination of a quad-band sweep frequency generator, a marker generator and an oscillographic device. Using the device "PNT-59" you can view the frequency characteristics of video amplifiers, intermediate frequency amplifiers of video and audio channels, frequency detector, high frequency amplifiers, PTP blocks, PTK and VHF FM, monitor the matching of the antenna cable with the TV input and antenna, determine the impedance high frequency coaxial cable. GCH frequencies: (0.4 ... 15), (27 ... 60), (55 ... 102), (174 ... 232) MHz. U out = (50 ... 250) mV. Sensitivity 0.4 mm / mV. Since 1963, a complete analogue of the device has been produced, under the name of the frequency characteristics meter "X1-7", and since 1971 the upgraded version "X1-7A". According to him there is no information, but most likely it is also an analogue of previous devices.
