The familiar video waveform display can show SD/HD/3G-SDI signals in RGB, YPbPr, YRGB, or pseudo composite. Signal components can be displayed in either Parade or Overlay mode. Cursors within the waveform display allow precise measurement of Voltage and Time to be made. The vector display offers user-selectable graticules, color targets (75% or 100%), and color axis.

 

With several sweep rates and easy control of vertical gain and horizontal magnification, you can efficiently monitor and measure video waveform parameters.

 

Specialized displays provide summarized, yet comprehensive reports of alarms, session, and status of content. Powerful displays such as Video Status show a condensed view of error statistics, signal format, presence of ancillary data, and more. These Tektronix-exclusive displays simplify monitoring tasks by providing important content information at a glance.

 

Errors in the displays can automatically be logged in the Error Log and provided as a report.

Wide Variety of Interface Support

In modern broadcast facilities, there are a wide variety of video and audio signal formats that require multiple tools to monitor the signal. The WFM2200A is able to support SD/HD/3G-SDI, AES/EBU digital audio, composite black burst or tri-level sync reference signals and optical SDI (Option SFP), which provides a one-instrument solution for a wide variety of formats.
 

The SDI A input supports SD/HD/3G-SDI (Option 3G) video signals. For a Dual Link SDI signal, both the SDI A and MULTI IN inputs are used.
 

The MULTI IN input also supports SDI, AES/EBU and LTC signals so that the user can easily determine the type of signal present on a cable.
 

The AES OUT and SDI OUT connectors are test signal outputs that can be configured as loop through outputs. The individual outputs for Audio and Video in conjunction with the SDI A and MULTI IN inputs allow the user to evaluate the variety of Audio/Video equipment that may require the audio/video signal with separate path.
 

The REF IN connector is used for receiving the analog composite or tri-level sync signal to measure the timing or check the sync status between sync signal and SDI signals. It is also used as a Genlock signal source for the generator function. In addition, the analog reference signal connected to this connector can be displayed as a waveform to quickly check the quality of the sync signal.
 

The optical SDI interface (Option SFP) is supported with a transceiver SFP module. The transceiver module provides both an input and output that can be used simultaneously. The output can be configured as loop output or as a test signal output. The SFP status display shows the module model name, mode, temperature and other status of the SFP module.
 

The STRESS LOOP connectors are a bi-directional passive signal path that can be used with a SDI test signal generated by the WFM2200A to test a signal path, or to add an additional cable length to a signal path to provide simple margin testing.
 

Quickly Diagnose and Isolate an Installation Issue

Within a broadcast facility, to maintain the SDI system it is important to ensure the health of the signal so that the clock and data are decoded correctly. CRC detection within the SDI signal can be used to count the CRC errors if present in the system.
 

The cable stress loop adds an additional 20 meters of Belden 1694A cable to the signal path. The use of the stress loop with CRC detection simplifies how to determine the cable margin of a system so that the user can quickly check they do not reach the “digital cliff” where the transmission error rate significantly increases.
 

Alarms, Quality Statistics, and Logging – Thorough and Fast Content Verification

The Tektronix WFM-2200A offers a variety of displays designed to show status at a glance, in addition to the status bar continually displayed at the bottom of the screen.
 

A comprehensive overview of the video content status is presented in the Video Session display. Offering a time-based summary of information, this screen is ideal for presenting evidence of compliance after content screening. Information on input format and session time is presented, along with statistics on Error Detection and Handling (EDH) / Cyclic Redundancy Check (CRC) and gamut errors.
 

The Alarm Status display provides continuous information on the state of each condition currently being monitored by the instrument.
 

To support unattended monitoring and QC applications, as well as provide documentation for service-level agreements, these instruments maintain an error log of 10,000 events, which facilitates the detection and correction of problems. Log entries are recorded with date, time of day, and time code (VITC, LTC, ANC). The error log can be downloaded to a USB flash drive or through a network connection to .TXT or .HTM formats for easy record keeping and processing on spreadsheets or database software.
 

Picture Display – Quick Visual Confirmation and Precision Content Adjustment

For a qualitative view of the content, a full-color Picture display is offered, which can be displayed as a full-screen presentation. This display is compatible with all input formats and features automatic adjustment for aspect ratio and number of active lines.
 

You can select bright-up conditions that show the location of RGB or composite gamut errors on the Picture display. The Line Select mode shows the location of the line currently selected within the Picture display.
 

Users can choose from several Safe Action and Safe Title graticules on the Picture display which help editors and operators easily identify incorrectly positioned video content such as graphics, titles, or logos.
 

Graticule choices include the Safe Action and Safe Title graticules defined in SMPTE RP218, ITU, and ARIB standards, plus two sets of completely flexible, user-definable graticules. These graticules facilitate editing tasks and reduce the need for format conversions.
 

Patented Tektronix Gamut Displays – Efficiently Detect and Allow Correction of Gamut Problems

The Tektronix-patented Diamond, Split Diamond, and Arrowhead displays simplify the process of verifying gamut compliance and are ideal for colorists, editors, and operators to visualize whether the content is RGB or Composite Gamut compliant with a single glance. Plus, they are designed to help isolate the Out-of-Gamut component just as easily. For SDI component content that is destined for broadcast in composite systems, the unique Tektronix Arrowhead display can be used to monitor Composite Gamut compliance without the need for a separate encoder. Within this display, a separate upper and lower luma-only gamut limit can be applied. Each of these displays offers user-selectable gamut thresholds so that operators can set monitoring limits appropriate to their specific operation and include a preset for EBU-R103. You can also select bright-up conditions to see the location of gamut errors on the Picture display. In addition, gamut monitoring is fully integrated with the powerful alarm logging and reporting capabilities of the instrument.
