Video Measurement: Oscilloscope or Waveform Monitor

Question: What scope do you recommend for use with HD video?  SD digital video?

Answer: Several Tektronix scopes (www.tek.com/oscilloscopes) offer video debug capability.

Our TDS3000C allows you to trigger on all lines or individual lines, odd, even or all fields on NTSC, PAL, and SECAM video signals.  The optional TDS3VID application module adds a video quickmenu, autoset, hold, line count trigger, video picture mode, vectorscope mode, HDTV format trigger graticules, and more. 

Our MSO/DPO4000 and MSO/DPO3000 scopes offer a fast waveform capture rate and intensity-graded view of the signal, providing the same information-rich display as an analog oscilloscope, but with much more detail and all the benefits of digital scopes.  Standard features such as IRE and mV graticules, holdoff by fields, video polarity, and an Autoset smart enough to detect video signals, make these scopes easy-to-use for video applications. They also allow you to trigger on all lines, odd, even, or all fields on NTSC, PAL, and SECAM video signals.  The video functionality on these scopes can be further extended with the optional DPOxVID video application module which adds triggers for HDTV and custom video, specifically 480p/60, 576p/50, 720p/30, 720p/50, 720p/60, 875i/60, 1080i/50, 1080i/60, 1080p/24, 1080p/24sF, 1080p/25, 1080p/30, 1080p/50, 1080p/60, and custom bi-level and tri-level sync video standards.

If your needs are related to content production, and not to design debug, you may be more interested in our waveform monitors, from our Video Test product line. The WFM5000 and WFM4000 waveform monitors offer uncompromised monitoring quality with sharp CRT-like traces, patented Gamut displays, Picture thumbnail, Display freeze and an Error log for 10,000 events for efficient content compliance verification. These models offer key features like Auto detect HD or SD input signals, 2 passive SDI loop through inputs, DVI-I display output, TandemVu™ display, Picture thumbnail, Picture display, Patented Gamut displays, Vector Display, Video Session Display, Alarm Status Display, 10,000 event Error Log.

If you are looking to do more than basic content monitoring, the WFM6120 / WFM7020 / WFM7120 family provides Tektronix’ superior video waveform monitoring and analysis capabilities required in Content Creation, Content Delivery, Research & Development, and Manufacturing applications. Precision and leading-edge capabilities such as Physical Layer Measurement, Digital Data Analysis, CaptureVu, A/V Delay Measurement and Simultaneous Input display make Tektronix the brand of choice for applications that require deep signal analysis and unquestionable accuracy.

I know that we’ve given you quite a few product options.  If you have additional questions, please give our Customer Care Center a call at 1-800-833-9200.  One of our application specialists can answer your specific questions and help you find the right solution.
