Video Measurement Set

Option 11

PAL Video Measurements

Recognized with eight technical Emmy awards and one Oscar for outstanding contributions to the television industry, Tektronix world class core competencies have enabled it to design and deliver the most comprehensive solutions in the industry.

The VM700T is a product of this core competency. Recognized as the defacto industry standard that keeps pace with evolving customer needs, the VM700T is a total solution for your baseband video and audio1 monitoring and measurement needs. Features such as an extremely fast and fully automatic measurement mode as well as full manual operation provides the first time user as well as the seasoned professional an unequaled value for their test and measurement investment.

Automatic video measurement set

The VM700T Auto mode makes standard video transmitter measurements quickly and automatically, including those specified in CCIR Rep. 624-1,Rec. 567, and Rec. 569. Both vertical interval and full field measurements can be made and compared with

user-definedlimits. A dual limit verification system is employed to generate a caution or alarm message when either limit is violated. Reports can be generated and printed automatically at operator scheduled times or triggered from a conditional event.

Graphic displays of measurements

Measure mode provides virtual real time graphic displays of measurement results automatically. Vertical interval or full field measurements including noise spectrum, group delay, K-factor,differential gain and differential phase are presented as clever, easy to understand interactive digital displays. Such displays are indispensable when extremely fast measurement update rates (up to 30 times a second) are required to provide instant feedback of critical adjustments and analysis of signal variations. User definable limits are visually integrated into each graphic display and can be used to trigger a measurement report or a user definable macro function. Such a function can, for example, dial out through a

modem to report measurement results or control a signal router. A relative to reference mode allows normalizing to a signal source or eliminate signal path errors from the desired measurement. Up to 2 video references can be stored in NVRAM. Additionally, after downloading to a PC through the VM700T FTP driver, the video reference can be uploaded to another VM700T for reuse. A running averaging mode can be used to reduce the effect of noise. When additional measurement data is required a user can custom configure measurement parameters and report format.

A powerful Test Signal search capability quickly and automatically locates and identifies valid test signals required for a selected measurement, eliminating the annoying and time consuming task of manually locating

test signals.

Digital waveform monitor/ vectorscope

The VM700T Waveform mode application provides real time graphics displays of the video signal allowing many additional measurements to be made manually. Easy to use measurement cursors are available to measure time, frequency and amplitude parameters of a video signal. These cursors allow a very quick and precise location of the 10%, 50% and 90% points on any transition. Cursor mode also employs an automatic calculation in the wave shape in the center of the display. The parameters calculated are sine peak- to-peakamplitude, frequency, and offset from blanking level. This is very useful for frequency response measurements with the Multiburst signal.

The waveform display can be expanded around any point both vertically and horizontally. Since the data is digitized, the display remains bright and easy to ready at all expansion factors. The scales automatically expand with the waveform, so all units are correct as displayed. A channel difference mode (A-B,A-C,B-A,

B-C,C-A,andC-B)is also provided. A screen memory selection enables Envelope mode, which is useful for looking at teletext, Jitter, or other changes over time.

Vector mode provides the normal vectorscope display. The vectors may be rotated or expanded, with the rotation angle and gain values displayed numerically on the screen.

A unique “Find ColorBars” feature searches all video for ColorBars and displays the vectors if found. The vectors can be referenced to either the selected channel’s burst or the burst of one of the other two channels or continuous subcarrier. The phase difference between the selected channel and the reference is always displayed.

Select Line in both Waveform and Vector modes can be used to quickly specify any line for

display or automatic measurement if it is the proper signal.

Picture mode

The signal source can be quickly verified using the picture display. Additionally, a “bright-up”line select mode allows a user to select any video line for use in Measure mode or for viewing in Waveform or Vector mode.

User programmable functions

Function mode is an extremely powerful feature that allows a user to store a sequence of user operations as a macro function for later “playback.”

For example, a set of measurements (complete with hardcopy commands) to be made on a transmitter demodulator video output, could be stored as a function labeled “DEMOD.” The function “playback” could then be initiated manually, remotely or completely automatically as a user specified timed event. Function files can be stored as a text file on a PC for editing, copying or uploading to another VM700T. Other function capabilities include controlling of external serial devices such as video/audio routers, switchers, signal generators, telephone modems and many other devices which support RS232 communications.

Hardcopy

All information on the screen may be printed in high resolution graphics on printers supporting PostScript®,Hewlett-Packard® LaserJet™, DeskJet™, and ThinkJet™, or24-pinEpson® graphics via the Centronics compatible parallel port or standardRS-232Cinterface.

Automatic measurement results in text format can be printed on most ASCII printers using the parallel or serial ports.

Remote Operation

The VM700T has a powerful and fully documented remote control language. The VM700T can

thus be operated from a remote terminal via RS-232Cto monitor unattended transmission systems. In addition, all files can be uploaded to a main computer, and downloaded to other VM700Ts. Two different protocols are supported: FTP (File Transfer Protocol) and TELNET. The user can also select a “no protocol” mode of theRS-232Cinterface when dealing with low baud rates. However, file transfers can only take place with FTP.

Specifications

The performance requirements cited in this section are valid only within the following environmental limits:

Temperature range of 0 to 50 degrees Celsius, with a minimum warm-uptime of 20 minutes. The following tables list each measurement and its performance requirement.

The range specifies the extremes between which a measurement can be made.

All measurement accuracies specified are valid only with nominal input signals of 1 volt pk-pk(± 6 dB) with an unweightedsignal-to-noiseratio of at least 60 dB on the incoming signal and a termination accuracy of ± 0.025% (Tektronix PN011-0102-01
