Info

1781R Video Measurement Set The 1781R is a wide bandwidth, multi-input analogue instrument which provides both waveform monitor and vectorscope functions. Precision measurements are facilitated by features such as cursors, a polar SCH phase display, and special differential phase and gain modes. VM700A Video Measurement Set The VM700A automatically monitors and measures the video signal, and provides digital waveform and vector displays for manual measurements. Spectrum displays and complete noise measurement capabilities are also available, as well as user programmable functions and hardcopy output.
About the Author Margaret Craig is an engineering manager in the Tektronix Television Division. Her experience includes circuit design for analogue waveform monitors and vectorscopes, as well as project leadership responsibilities. She holds a BSEE from Iowa State University.
