The CALIBUG HDTV turns any PC or LAPTOP equipped with HD Component Video
or Composite/YC video output into an HDTV, DV, NTSC or PAL Video Test Signal Generator
rivaling those costing thousands of dollars!

Use the NTSC/PAL, Y/C, SVGA, DVI, or HDMI output of your video card to produce quality test patterns.


Remember the CALIBAR by Newtek? It was a great idea ahead of its time, but its no longer manufactured....and it cost upwards to $600 ! We once sold this product, and we kept getting requests for it. We had a regular need to provide test signals for our weather broadcast systems during setups at TV stations. An early design became popular with TV station engineers, so we decided to design our own low cost USB version.


      The Calibar by Newtek- A great tool but no longer available

The CALIBUG HDTV by ItWorks - Over 200 patterns and tests, in a Pocket USB Tool!

Our CALIBUG HDTV is a unique USB device and a dedicated custom application of our popular NTSC Video Reference CD and DVD, plus all the features your need for DV and HDTV testing too. We've taken the best features of those programs, and combined it with USB flash memory technology to create a pocket portable Video Test and Multimedia Reference generator that will plug into any PC or Laptop and turn it into a high quality Video Signal Reference and Multimedia Tester. Like our CD ROM, The PC or Laptop used needs to have a DVI (HD) or NTSC Composite or S-Video (Y/C) output for use with broadcast video equipment and other professional video gear. Many PC's and Laptops Today have this video output feature built right in. Of course, if you need to add broadcast quality video to a PC or Laptop, we have solutions for you!

We also offer an optional HDTV component video (Y/Pr/Pb) converter that allows SVGA cards with DVI-I outputs to generate HDTV test signals using our Calibug HDTV. Both 720p and 1080i formats are supported! Only $29.95, add to cart below with your order.

See list of compatible SVGA video cards below:

NOTE: SVGA Cards must support 1280x720 resolution for HDTV 720p and 1920x1080 resolution for HDTV 1080i and have a DVI-I connector or direct Y/Pr/Pb component video output. For DVI-I connectors, HDTV component video can be obtained using our optional DVI-I to HDTV converter.

This adapter (and the Calibug) works with most modern PC video Cards that have an SVGA, DVI, or NTSC/PAL/ Y-C output (for low resolution SD tests)

  • NVIDIA GeForce series of video cards GT6200LE through 9800GTX, plus many others.
  • ATI series of video cards Radeon, Fire GL and Pro, plus many others
  • Other video cards - if it has a DVI output and supports 1280x720 resolution for HDTV 720p and 1920x1080 resolution for HDTV 1080i it will likely work. The Calibug will also work with older video cards, using SVGA and the NTSC/PAL/Y-C output for standard definition tests.

Be sure to check your PC video card specs and output options.


Or use the DVI-D: This GOLD PLATED adapter converts HDMI Male to DVI Male connector. A DVI to HDMI adapter is used to connect older home theater equipment with DVI connectors to newer HDTV televisions and projectors which have HDMI connectors.
