1. 0150 008 Ethernet connection 1741C Analog Dual Standard Waveform Monitor User Manual Operating Basics Tutorial Timing a Studio Using the Traditional Method Your instrument supports multiple methods and techniques for timing a studio all of which require an external reference to your instrument Timing a studio involves adjusting the references going to different sources so that their output feeds have the same timing when they arrive at a common point such as a production switcher For analog composite systems the timing may need to be matched within a small part of a subcarrier cycle to prevent hue shifts when switching between sources Following are procedures for timing a studio using various methods Your instrument makes the traditional method of comparing Horizontal and Vertical timing easier by providing flexible tiles and a Freeze function To time a studio using the traditional method you store an input as a baseline and compare signals that you time against the baseline 1 Selecta tile in which to time the active input Select WFM 2 Apply the first input signal to the appropriate input terminate it properly and select it 3 Push and hold the WFM button From the Display Mode submenu select a display mode that is appropriate to the signal that you input 4 Apply the house reference signal to the external reference input terminating it properly 5 P
