  • Page 13: Introduction

    The OTR also has the ability to freeze the screen display and to capture images from the incoming video The OTR 1001 is available in 1001c and 1001m versions. The OTR 1001c is designed to be driven from the control panel on the front of the instrument but both the OTR 1001c and the OTR 1001m may be driven using a mouse and keyboard.

  • Page 14: Safety Statement

    Ensure that the unit is properly ventilated. Do not operate in an explosive atmosphere or in damp/wet conditions. Do not operate the OTR 1001 with either the cover or any of the panels removed or otherwise displaced from their standard positions.

  • Page 15: System Features And Instrument Options

    A.1 System Features and Instrument Options The main features of the OTR 1001 are summarised in the following table. Feature Description Centred around a single ‘View’ window – divided into ‘tiles’, each of which Monitoring system may be used to show the result of a separate type of analysis applied to the video under test.

  • Page 20: Adding The Graphics Display

    Adding the Graphics Display The graphics output from the OTR 1001 can be displayed by plugging a DVI monitor or a VGA monitor into the DVI-I Out connector on the back panel. Depending on the VGA monitor cable, this can either be plugged in directly or via the VGA – DVI cable included with the OTR.

  • Page 21: Common Set-Ups

    External sync Monitoring an SDI video signal Setting the OTR 1001 up to monitor a video signal typically just requires a BNC cable from the video source to either IN 1 or IN 2. Where dual-link video is to be analysed, two such cables are needed – one for each link – one connected to IN 1 and the other to IN 2.

    OTR’s test signal generator to be synchronised with an external reference clock. The OTR 1001 can be linked both to the source of the reference signal and to other instruments using the same reference signal through the Reference Loop connectors on the back panel.

  • Page 23: Power Up

    Applying Power Connect the supplied power cord to the power connector on the back panel of the OTR 1001. When power is applied to the machine, the power button on the front panel will be lit and either showing as red, green or orangey-red depending on the state the machine is in.

  • Page 24: Display Modes

    ESC toggles between these two display modes. Whether the OTR 1001 is working in Full Screen mode or Windows mode is one of the aspects of the system that is recorded when the OTR is shut down and automatically restored the next time the OTR is run.

    2. Confirmation of your registration will be provided in an email. When this confirmation arrives, return to the Software Downloads page of the OmniTek web-site, login, then download the latest version of the OTR 1001 software from the Downloads page that is displayed.

  • Page 27: General Care

    A.7 General Care The OTR 1001 should be kept encased in the enclosure in which it is supplied or mounted in a standard rack unit. This will avoid dust getting into the hardware. We also recommend keeping the exterior of the OTR 1001 clean (see below). You should also have any damaged, worn or missing parts replaced as soon as possible through your OmniTek dealer.

  • Page 29: General Controls

    This section describes the facilities the OTR 1001 offers for selecting program features. B.1 General Controls For some versions of the OTR 1001, the main control is provided by the buttons on the instrument’s front panel (as described below). However, for all versions of the OTR 1001, there is the option of driving the system using a mouse and keyboard as described later in this section.

  • Page 32 View menu The View menu controls the display of the various toolbars used by the OTR 1001 application. In general, clicking on an entry to tick it causes the selected toolbar to be displayed. Similarly, clicking on an entry to clear the tick causes the selected toolbar to be closed.

  • Page 33: Toolbars

    Toolbars The OTR 1001 in Windows mode also offers a range of toolbars through which to call up the different facilities offered by clicking with a mouse. These toolbars are displayed either side of the main window. Some of these are applicable across the whole system; others only apply to particular window displays.
