  • Page 45: C: Automated Control

    C : Automated Control The Omnitek Ultra is highly suited to being used in routine monitoring applications through its support for remote control using the SNMP protocol. SNMP stands for Simple Network Management Protocol and it is commonly used in production line testing both to run the required sequence of tests and to monitor the instrument under test for conditions that warrant attention.

  • Page 46: Set-Up

    3. Programming the device from which the systems are to be monitored with the appropriate SNMP Manager application. 4. Uploading a copy of the Omnitek Ultra MIB to the SNMP manager. 1. Linking the boxes into a single LAN Typically either the device from which the automated control is to be driven need to be added to the network that the Ultra is already on or the Ultra needs to be added to a network that includes the device from which it will be remotely controlled.

  • Page 47: Scope

    C.3 Scope The best way to discover about the OIDs used by the Omnitek Ultra, their meanings and their possible values is to load a copy of the MIB file into a ‘MIB Browser’ such as that provided by iReasoning.
  • Page 48 ------------------------------- General: Automated Control -------------------------------- In order to see the value associated with a particular parameter or set of parameters on a particular Ultra system, the current values need to be fetched. In the iReasoning browser, this is done by first setting the address of the Ultra, then giving the instruction to Walk.

  • Page 57: G Additional Sdi Output Features

    Additional SDI Output Features Video fed to the SDI Output ports on an Ultra can be further modified as follows: 1. Where the signal is output over dual or quad links and the Ultra includes a built-in generator, the signals on the subsequent links can be advanced or delayed relative to the first link.

  • Page 58: Interlink Delay Insertion

    --------------- Conversion Facilities: Additional SDI Output Features --------------- G.1 Interlink Delay Insertion Where dual- or quad-link video is output using the SDI ports on the Ultra and the Ultra includes the built-in generator, it is possible to advance or delay individual signals relative to the signal on the first link by the equivalent of up to 64 pixels or up to 128 pixels, depending on the Output Video Standard.

  • Page 59: Jitter Insertion

    --------------- Conversion Facilities: Additional SDI Output Features --------------- G.2 Jitter Insertion A good way to determine the robustness of an SDI connection is by subjecting it to different levels of jitter. Where the Ultra includes the PHY and PHY_ADV options plus either the GENERATE or the CONVERT option, it also offers facility to insert jitter into output video stream.

    O : Status Real time status information about the video signal that is currently being analysed may be displayed by calling up the Status View. Aspects of the signal where errors have occurred are highlighted in the displays to draw your attention to these. O.1 The Status View The Status View offered by the Ultra is one of the displays that can be called up on the Viewer window.

    Section 4: Physical Layer Analysis This section describes the facilities offered on an Omnitek Ultra for examining physical characteristics of the video signal such as signal amplitude, rise & fall times, jitter and timing. Some of these facilities are provided as standard on the 4K Tool Box and become available on other Ultra systems by adding the PHY option.

  • Page 99: S: Eye & Jitter Measurement

    S : Eye & Jitter Measurement This section describes the tools the Omnitek Ultra provides for assessing video integrity of SDI video transmissions and for locating sources of jitter. To analyse any SDI video signal up to and including 6G-SDI, the system you use will need to include the PHY option, together with any VIDEO_xx options that are needed to support the video standards that you wish to analyse.
  • Page 100 ------------------------------- Physical Layer: Eye & Jitter -------------------------------- Improving the Noise Floor The Ultra incorporates both a 148.5MHz clock and a 148.35MHz clock in order to support the different frame rates at which video can be delivered. To give the user full flexibility over the range of actions that can be carried out at the same time, these clocks run concurrently.

  • Page 101: Facilities Offered

    ------------------------------- Physical Layer: Eye & Jitter -------------------------------- S.1.1 Facilities Offered The following displays are offered: 1. Eye Waveform giving a graphical representation of the signal which in turn gives a physical representation of the different signal parameters (amplitude, unit interval, rise time, fall time etc.).

  • Page 102: Eye Waveform

    ------------------------------- Physical Layer: Eye & Jitter -------------------------------- S.2 Eye Waveform The Eye Waveform presents the data carrier signal in the way it might be displayed on an oscilloscope, though produced in a very different manner. While the oscilloscope is able to work directly with the data carrier signal, the Eye Waveform displayed on the Ultra is built up through time equivalent sampling of this analogue signal.

  • Page 103: Selecting The Eye Waveform Display

    ------------------------------- Physical Layer: Eye & Jitter -------------------------------- The Eye Waveform also allows you to judge how well the signal is synchronized with the signal clock, whether the signal suffers from overshoot or undershoot, and whether the signal is likely to be correctly interpreted by the receiver.

  • Page 104: Obtaining Signal Parameters From The Eye Waveform

    ------------------------------- Physical Layer: Eye & Jitter -------------------------------- Eye Amplitude Measurement Method The Eye Amplitude is determined automatically but some details of the calculation are set on the Video page of the Configuration window. The parameters concerned are included in the Eye Amplitude Measurement section of this page.

  • Page 115: Set-Up To Give Line-Based Timings

    ---------------------------------- Physical Layer: Timing ----------------------------------- T.2.2 Set-Up to give Line-Based Timings How the Lines and Pixels values should be interpreted depends on the setting of the Line Based timing option in the Timing section of the Video page of the Configuration window. When this option is turned Off (0), the advance/delay is always the number of lines plus the number of pixels.
