The Tektronix WFM2300 Waveform Monitor provides a solution for video installation and maintenance applications in a convenient, portable form factor. It features a high-brightness, low-power consumption LED-backlit display and can operate on an internal battery as well as DC input. Standard configuration provides multi-format support for HD-SDI (SMPTE 292), SD-SDI (ITU-R BT.601), and Dual Link (SMPTE 372) signal formats. The monitor offers automatic format detection, and with Option 3G supports Level A and Level B SMPTE 425/424 formats. The SMPTE 297 compliant optical interface (Option SFP) offers an input and output connection through an SFP transceiver module.

The Eye and Jitter measurements available for input A on the WFM2300 performs SDI physical layer measurement on the SDI signal. Option 3G is required to support 3G-SDI inputs. The cable simulator/stress capability helps the engineer to perform cable margin testing to ensure that the signal can be transmitted from point A to point B.

Audio monitoring support for up to 16 channels of Embedded AES/EBU Audio provides a variety of audio level bar monitoring, multi-channel surround sound display 1, and flexible Lissajous display. Option DBE allows Dolby E audio stream monitoring, peak level audio bar display, and metadata information display. Also, an internal speaker or headphone port can be used for easy compliance verification of digital audio without the need for an additional piece of equipment.

The WFM2300 offers 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. The intuitive user interface provides backlit buttons and online help. 32 user-configurable presets allow users to recall commonly used configurations tailored to your personal work practices. These presets can be transferred to and from other units (same model) using the USB port. An Ethernet port allows for easy download of screenshots and the Error Log.

This "See and Solve" monitor simplifies video monitoring tasks such as calibration, error detection, and content correction, allowing the user to detect errors at a glance and troubleshoot them efficiently. It offers sharp CRT-like trace quality for clear waveform monitoring with the look and feel of an analog display. 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.

The WFM2300 portable platform offers the physical-layer signal measurements suitable for Installation and Maintenance applications. It provides unique capabilities such as reporting jitter levels above 1 UI and providing various jitter filters from 10 Hz to 100 kHz for SD/HD/3G-SDI signals. An easy-to-interpret gauge provides direct readout for jitter measurements. Users can configure timing jitter, alignment jitter, or other jitter filter to effectively isolate the sources of jitter. The SDI Status display summarizes key signal parameters such as signal strength, cable loss, and estimated cable length measurements. With FlexVu, users can display the jitter value and cable parameter measurements to help quickly diagnose and resolve problems related to SDI timing jitter or cable attenuation. The infinite persistence mode of the waveform monitor can also be used to more easily view the eye opening of the physical-layer signal. In addition, the WFM2300 can also perform automated eye amplitude, automated rise/fall time, automated overshoot measurement, and provide jitter waveform display to view jitter related to line and field rates. All of these capabilities help engineers in the field to detect and diagnose signal quality problems quickly and efficiently.

In modern broadcast facilities, there are a wide variety of video and audio signal formats that require multiple tools to monitor the signal. The WFM2300 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 and provides monitoring of eye and jitter measurements. 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 WFM2300 to test a signal path, or to add an additional cable length and interfering signal to a signal path to provide simple margin testing.

In a broadcasting facility, it is important to ensure the health of the signal so that the clock and data are decoded correctly and the health of the SDI system is maintained. CRC detection within the SDI signal can be used to count the CRC errors if present in the system. The measurement, however, may take minutes or hours to ensure that the signal is error free.

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.

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.
