  • Content QA of Composite and Component Video in Production and Postproduction

The 1741C is the latest analog waveform monitor from Tektronix that features user interface tools to simplify operations. Its precise displays provide high-quality monitoring for traditional analog composite (PAL and NTSC) or component systems.

This instrument supports four analog composite signal inputs with waveform, vector, SCH, and picture functions. The input ports can also be used for RGB signals.

The 4-tile FlexVu display and convenient picture thumbnail maximize the versatility of the 1741C.

For camera alignment, the user can display one, two, three, or four waveforms simultaneously and overlay just as many vector displays, thus facilitating monitoring of multiple cameras during content acquisition.

Powerful tools such as timing display, VITC, or LTC decode, freeze capture, video session, alarm status, and error log allow for deeper signal inspection to enable superior video production and delivery quality.

Ease of Use

The Intuitive User Interface provides backlit buttons.

32 user-configurable presets allow users to recall commonly used configurations tailored to your personal work practices.

For remote operation, the Ground-closure Interface allows for remote selection of input or preset recall.

The user can download screenshots using the USB or Ethernet port.

The error log can be downloaded using a web browser.

The unit provides an XGA output for instrument display on an external monitor and picture monitor output for analog composite signals.

Time and voltage cursors in waveform display can be used as reference points or to measure values. User-defined labels allow for easy identification of input sources on the screen.

See and Solve with Tektronix Displays

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

The FlexVu 4-tile display provides maximum flexibility to increase your productivity. With FlexVu, you can create a multiview display tailored to your specific needs and work practices.

The Video Session, Alarm Status, and Error Log displays are effective tools to verify the format and quality of the signal and allow for efficient detection and correction of errors by providing key content information at a glance. The error log captures up to 10,000 events and can be easily downloaded using a web browser.

The freeze function on the 1741C allows comparing of the frozen display to the live signal, facilitating tasks such as reference setting. A bitmap of the display can be downloaded using a web browser for easy documentation.

With 32 user-configurable presets, operators can recall commonly used configurations for faster setup of the 1741C.

Sharp Waveform Display – Clear Measurements

Tektronix displays offer the sharpest CRT-like trace quality for clear waveform monitoring without pixelation distortions. With several sweep rates and easy control of vertical gain and horizontal magnification, you can efficiently monitor and measure video waveform parameters.

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

Both fixed and variable vertical gain is 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.

With the time and voltage cursors in the waveform display, users can easily reference points or measure values. Users can also define labels to quickly identify the input sources active on the waveform display.

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.

The vector display offers user-selectable graticules.

Analog Video Multiformat Support

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 PAL and NTSC inputs with format auto-sensing.

Timing and Synchronization Made Easy

The patented Tektronix Timing display makes facility timing easy through a simple graphical representation which shows the relative timing of the input signal and the reference signal on an X-Y axis. The display also has numeric readouts of the timing difference relative to the reference, showing vertical timing as number of lines and horizontal differences in μs.

The SCH Phase display helps quickly verify this critical timing parameter of composite analog video signals.

The 1741C provides VITC or LTC Time Code decode and display plus LTC waveform display for longitudinal time code amplitude and synchronization monitoring.
