Tektronix 1780R Video Measurement Set Manufacturer: Tektronix Model: 1780R Unit comes with items shown in pictures. Accessories: None Description The Tek 1780R Series Video Measurement Set offers features for precise evaluation of studio and transmission performance. This multi-function instrument is a wide bandwidth, multi-input, waveform/vector/SCH measurement package. The advantages of separate waveform and vector instruments are provided in a single rack width, 5.25 in. or 133.4 mm high package. In addition, specific measurements take advantage of the 1780R Series' shared waveform monitor and vectorscope internal processing. Separate, optimized waveform and vector display CRTs allow simultaneous monitoring of several video parameters.
