Showing Results for Tektronix TDS3VID

All TDS3000 Series oscilloscopes come standard with NTSC, PAL and SECAM (All Fields or All Lines) triggering capability. The TDS3VID application module extends this basic video triggering by adding the following features.

• Video QuickMenu - This Video QuickMenu function allows you to display a bottom and side menu that contains video functions useful for displaying and measuring broadcast standard waveforms, including trigger source, when to trigger, video graticule and video autoset
• Video Autoset - The autoset function automatically adjusts the vertical, horizontal and video trigger settings to display a video waveform triggered on all lines and fields. You can then manually adjust controls to optimize the display. This function is available in the Video QuickMenu and in the Acquire menu
• Custom Video - Using the custom video function allows you to specify custom horizontal scan rates in order to trigger on non-broadcast video waveforms, such as those used by computer monitors and medical equipment displays. This following figure shows the TDS3000 scope triggering on a scan rate of 26.2 kHz
• Line Count Trigger - Sometimes it is necessary to view a single line of the video waveform. For example, the programming information in the NTSC signal is sometimes found on Line 20. Line Count triggering allows you to trigger on any particular line by scrolling through the line numbers and selecting the one you want
• Field Holdoff - The field holdoff function provides the capability to specify a number of fields to wait before re-enabling triggering. This allows you to trigger on a single field (for example, field 1 or field 3 of NTSC) instead of both field 1 and field 3
• Video Graticules - The video graticule function provides the capability for the user to change the standard oscilloscope graticule to either IRE or mV depending on the signal format. Video graticules make it easier to measure and analyze video waveforms
