Display Information Display Information This section describes instrument displays and their respective pop-up menus. NOTE. All pop-up menus are displayed by pressing the speciﬁed button for three seconds. To hide a pop-up menu, press the speciﬁed button again. Waveform Display The WFM button displays the Waveform (WFM) display, which is the voltage versus time display used to view a waveform.
Page 30 Display Information To choose how the signal components are displayed in the active tile, use the Display Style menu setting (SDI inputs only) to select: Parade style - has all the components shown one beside the other. Overlay style - has all the components drawn at the same location so that they appear one on top of the other. The Waveform pop-up menu Filter selection allows you to select ﬁlters to be applied to the video.
Page 31: Vector Display
This is a Tektronix proprietary display and is for SDI signals only. To select which scaling should be used in the active tile for either the Vector or Lighting display, use the menu to select 75% or 100% scaling.
Page 32: Timing Display
Pressing the MEAS button displays a Tektronix proprietary display that simpliﬁes measuring the timing difference between two signals as the timing is corrected. Using the Tektronix Timing display enables you to easily compare and correct the timing between two signals.
Page 33 Display Information Save Offset allows you to measure the timing between inputs or to match multiple signals. To select the deﬁnition for the zero timing offset, use the Relative To: menu entry to select one of the following: Rear Panel, which means the timing offset will be shown as zero when the two signals are timed down at the rear of the instrument.
Page 34: Picture Display
Display Information For a case where multiple relationships would display, consider an input of 1080p/23.98 Hz with a reference of NTSC/59.94 Hz: The different rates result in timing relationships between the signals that repeat once for every four ﬁelds of the input and ﬁve frames of the reference (shown right).
Page 35 Display Information VChip, CC-Display, Teletext, and Safe Area Graticule Characteristics: 1. VChip Area: Displays detected VChip ratings from any of these systems: MPAA (US), TV (US), Canadian English, and Canadian French. VChip information is labeled CA (Content Advisory). 2. Safe Graticules: SMPTE, BBC, and ARIB B-4 standards for safe area graticules allow for selection of up to two Safe Area and two Safe Title graticules.
Page 36 Display Information NOTE. See Monitoring Closed Captioning (CC), Teletext, and Safe Area Compliance in the Quick Start User Manual. PICT Pop-up Menu The Picture pop-up menu enables you to optionally display elements of the video signal outside the active video, turn on display of Close-Caption (CC) text overlaid on the picture, and turn on up to four save area graticules, and otherwise control the PICT display.
Page 37: Audio Display
Display Information Audio Display Pressing the AUDIO button brings up the Audio Display. The Audio display provides level meters and a phase display for monitoring audio signals. The Audio display always shows the level meters and correlation meters.

Page 38 Dolby Guardband thermometer is displayed on the Audio display so that you can monitor whether or not guardband limits are being exceeded. NOTE. The surround display is described under Monitoring Surround Sound in the WVR6020, WVR7020, and WVR7120 Quick Start User Manual. NOTE.
Page 39 Display Information UNLOCKED. The instrument is not locked to an incoming signal on the indicated input channel. Data cannot be decoded and all data and other errors are ignored. This means that if an AES input is selected, nothing recognizable is present on the input, or if embedded audio is selected, the VIDEO input is unrecognizable.
Page 40: Ltc Waveform Display
Display Information To add a multi-channel surround sound display to the audio tile, set Aux Display to Surround Sound in the Audio pop-up menu.
