The WFM5000 and WFM4000 Portable Video Waveform Monitors provide an ideal solution for basic video and audio monitoring needs with an integrated LCD high-brightness display in a convenient 3RU, half-rack, short depth form-factor, suitable for space-constrained environments.

These versatile instruments provide options to accept power from a 12 VDC source, a battery, or a 100-240 VAC converter.

Both models come standard with support for 16 channels of Embedded Audio and 1 input for 2 channels of Digital AES audio.


Supports SD-SDI (ITU-R BT.601) monitoring only.

These instruments provide the reliability of the Tektronix waveform monitors family in a portable, basic monitoring product.

Tektronix Excellence

WFM5000 and WFM4000 offer 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.

Digital Audio and Video Monitoring in One Instrument

These instruments provide standard digital audio monitoring with Audio Bars, Lissajous Displays, and Front panel headphone port for easy compliance verification of digital Audio without the need for an additional piece of equipment

Ease of Use

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) via the front panel USB port.

The Passive loop-through inputs allow for transparent monitoring at any point of the signal path even if instrument power is off.

An Ethernet port allows for easy download of Screen shots and the Error log.

See and Solve with Tektronix Displays

The See and Solve displays in Tektronix video monitors simplify video monitoring tasks such as calibration, error detection and content correction allowing to detect errors at a glance and troubleshoot them efficiently.

Tektronix displays offer the sharpest CRT-like trace quality for clear waveform monitoring with the look and feel of an analog display. 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 in a condensed way 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.

The vector display offers user-selectable graticules, color target and color axis.

Patented Tektronix Gamut Displays – Efficiently Detect and Correct Gamut Problems

The patented Tektronix Diamond and Split Diamond displays enable Colorists, Editors, and Operators to visualize whether the content is RGB 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. This display is very useful for camera balancing.

Each of these displays offers user-selectable Gamut thresholds so Operators can set monitoring limits appropriate to their specific operation. In addition, Gamut monitoring is fully integrated with the powerful alarm logging and reporting capability of the WFM5000 and WFM4000.

Sharp Waveform Display – CRT-like Trace Quality

A complete range of display options lets users choose between parade and overlay presentation of SDI signals in RGB, YPbPr, YRGB or pseudo-composite formats.

Full horizontal timing flexibility is provided with 1Line, 2Line, 1Field and 2Field sweep modes, with or without magnification.

Both fixed and variable vertical gains are offered, each with the outstanding accuracy and repeatability that comes from a fully digital design.

The Line Select provides a line marker in full screen and thumbnail picture modes.

Vector Display

The vector display is offered with selectable 75% and 100% targets.

Each display automatically selects the appropriate graticule based on the input format.

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 brightup 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 totally flexible, user-definable graticules.

These graticules facilitate editing tasks and reduce the need for format conversions.

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

The WFM5000 and WFM4000 offer 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 compilation 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 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 TXT or HTM formats for easy record keeping and processing on spreadsheets or database software.

Digital Audio Capabilities – Equipped Standard

Audio monitoring capabilities for both digital AES and Embedded audio are available as standard in the WFM5000 and WFM4000.

The instruments feature Level Bars display and both Bars and Lissajous display. These displays can be selected to provide monitoring for both embedded and AES digital audio formats with up to eight channels (2 channels for AES Audio).

The level meters offer selectable meter ballistics and scaling plus they are user-configurable. The over and silence settings augment digital clip and mute detection by letting users select levels to represent these conditions in the analog audio domain.

The Audio Session display records the highest true peak, as well as the number of mutes, clips, overs, and silences during the session time. Tektronix instruments provide accurate peak level measurements.
