  • Page 19: Rackmount Installation

    Installation Rackmount Installation Install your instrument into a standard instrumentation rack. The following procedure will help you do this for both the standard instrument configuration and for instruments configured with the remote front panel option. Your instrument ships with hardware for rackmounting and fits in a standard 19-inch rack.
  • Page 20 Installation 2. Screw-mount to the front rail as shown. 3. Install bar nut if the front rail mounting hole is not tapped. 4. For a deep configuration, rear mount as shown. Make sure that the stationary sections are horizontally aligned, level, and parallel.
  • Page 21 Installation To Install the Instrument 1. Pull the slide-out track section to the fully extended position. 2. Insert the instrument chassis sections into the slide-out sections. 3. Press the stop latches, and push the instrument toward the rack until the latches snap into their holes.

  • Page 22: Connecting A Display

    Installation To Remove the Instrument 1. Before removing the instrument, be sure to disconnect all cabling. 2. Loosen retaining screw and pull instrument outward until the stop latches snap into the holes. 3. Press stop latches (visible in the stop-latch holes) and carefully slide the instrument free from the tracks.

  • Page 23: Connecting Power And Powering On/Off

    Installation 1. Loosen the front-panel knurled retaining screw. 2. Grasp the front handles and pull the instrument out until all three slide sections latch. The instrument is firmly held in this position and you are now ready to connect power and signal cables to the instrument.

  • Page 24: Installing In A Video System

    Installation Installing in a Video System This instrument can operate almost anywhere in the distribution system due to its high impedance, bridging, and loop-through inputs. This section describes two types of connections and presents information on line termination. The following diagrams are for serial digital systems, but similar connections are common for the analog composite inputs on this instrument.
  • Page 25 Installation For monitoring serial digital signals around a routing switcher 1. Connect your serial sources through a patch panel to a serial router. 2. Connect the output of the serial router to a SDI loop-through input for comparison. 3. Connect the other SDI loop-through input to the patch panel to jumper the signal that you want to compare to signal connected in step 2.
  • Page 26 Installation The loop-through capability is especially useful with the EYE and PHY options because it allows inspection of the actual signal on the cable. However, the signal received by the instrument is also dependent on the quality of the downstream cabling and termination.

    Getting Acquainted With Your Instrument Getting Acquainted With Your Instrument Instrument Display This instrument uses FlexVu™, which is a flexible, four-tiled display that can show four tiles at one time or a single, full-screen sized tile. Each tile can display a different measurement, effectively creating four independent instruments. In order to allow the tiles to function independently, most of the controls affect only one tile at a time.

  • Page 59: Checking Chroma/Luma Delay (Lightning Display)

    Checking Chroma/Luma Delay (Lightning Display) Checking Chroma/Luma Delay (Lightning Display) The Lightning display can be used for interchannel timing measurements. If the color-difference signal is not coincident with luma, the transitions between the color dots will deviate from the center mark of a delay scale. The amount deviated represents the relative signal delay between luma and the color-difference signal.
  • Page 60 Checking Chroma/Luma Delay (Lightning Display) 10. Determine where transitions intersect the delay scales and derive the timing error in nanoseconds, as deflected from the center mark: The center mark of the nine marks spanning each green-magenta transition is the zero error point. Alignment to a mark towards black means the color-difference signal lags with respect to luma.

  • Page 61: Checking Gamut

    Checking Gamut Checking Gamut Signals that are legal and valid in one signal representation may not be legal in another representation. Specifically, signals which are legal in the Digital YCbCr representation may not be legal if transcoded to RGB or encoded to NTSC / PAL. Any signal that fails this test is considered out of gamut.

    Monitoring Audio Monitoring Audio Your instrument provides several methods for monitoring audio signals. It can measure levels, monitor phase, display phase correlation, and monitor surround-sound audio. You can specify meter ballistics and scales, set test and peak program indicator levels, and specify how phase is displayed. NOTE.

  • Page 118: Usage Notes

    Monitor Dolby-Based Surround Sound Usage Notes Your instrument determines the downmix based on several parameters within the Dolby metadata and the Dolby downmix selection. For example, if the Dolby Audio Status screen shows Extended Bitstream information indicating that the preferred downmix is Lt/Rt, the center channel is attenuated by -3dB and the surround channels are attenuated by -6dB before they are combined into the stereo downmix.

    Using Alarms Using Alarms Alarms can be configured so that your instrument automatically monitors parameters and reports when those parameter limits are exceeded. The procedures that follow describe how to configure response types for individual alarms, how to enable them, and how to monitor them. Configuring Alarms Alarms may need to be configured in the Configuration menu use.

  • Page 134: Application Example

    Application Example Application Example Timing a Studio 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.
  • Page 135 Using the Timing-Display Method The Tektronix Timing Display provides a quick, easy way to measure the timing of an input relative to the external reference: The rectangular display automatically scales to match the input signal. For progressive signals, the display represents one field;...
  • Page 136 NOTE. See Timing Displays for Simple Versus Complex Timing in the WVR6020, WVR7020, and WVR7120 User Technical Reference on the User Documentation CD that came with your instrument for more information about complex timing displays and their elements.
  • Page 137 Application Example NOTE. As you adjust timing, the circle representing the input timing may jump occasionally. This is because the color frame detection circuit can be temporarily disrupted as the signal shifts. The jump is often a multiple of the field time. The circle will settle back to the correct location in a second or so.
  • Page 138 When timing analog composite signals, adjust the system phase with the Vector display. The Vector display is described in Timing Displays for Simple Versus Complex Timing in the Display Information chapter of the WVR6020, WVR7020, and WVR7120 User Technical Reference manual found on your User Documentation CD.
  • Page 139 Application Example NOTE. If you have an input and reference combination that requires multiple timing indicator circles, then it can be misleading to compare timing offsets between multiple inputs. Because the timing display chooses the smallest of the possible timing offsets, if a large timing difference exists between two inputs, then they may not be matched. This problem will also occur using traditional timing methods unless one uses something similar to the SMPTE318 10 field flag to identify a specific sub-multiple of the reference.
