Leader Instruments Adds SDI And IP Solutions

Leader Instruments recently announced several ZEN Series enhancements and a new sync generator.

Leader Instruments recently introduced several new T&M enhancements and solutions for SDI and IP. The company has enhanced the IP measurement capabilities of its LV5600 waveform monitor and its LV7600 equivalent rasterizer.

The video over IP measurement function specified in SMPTE ST 2110 and SMPTE ST 2022-6 now provides nine extra tools:

  1. Buffer measurement based on SMPTE ST 2110-21.
  2. Packet error and packet jitter insertion to the IP test signal generator.
  3. Addition of lip-sync test pattern to the SER32 option.
  4. IP to SDI conversion insertion of payload ID.
  5. Simultaneous display of ports 1 and 2 packet jitter and PTP measurement.
  6. Event log displayed in PTP time.
  7. PTP grand master clock information is displayed from the PTP announcement message.
  8. Graph data such as packet jitter and PTP are output as a CSV file.
  9. Audio and ANC can also be displayed on the ST 2110 packet jitter graph. The toolset is available as a freely downloadable upgrade.

Enhanced SDI

Enhanced SDI measurement is being introduced for all five ZEN series models. The SDI measurement function specified in 12G/6G/3G/HD-SDI now provides two new extra tools. First of these is a BT.709-compatible vector scope scale. UHDTV (ARIB STD-B66) and HLG color bars (ARIB STD-B67) contain BT.2020 and BT.709 colors.

A scale has been added to allow the vector coordinates of BT.709 color bars to be checked easily. This feature is intended for use in BT.2020 and BT.709 video content production. Second of these two new features is enhanced support for EIA-708/608 close-caption data in 4K, with support for both 3G-SDI quad-link and 12G-SDI. It is available as a freely downloadable upgrade.

New SDI and IP Video and Audio Sync Generator

Leader Electronics also recently added to its portfolio of broadcast test instruments and signal generators. Designed for use in both SDI and IP infrastructure, the LT4611 is a 1U full-rack-width generator producing analog video sync, audio word-clock signals and SMPTE ST 2059-2 profile.

Based on the established and proven LT4610, it has a lower entry price point giving broadcasters the freedom to select the features they need as the industry progresses from SDI to an increasingly IP-dominated world.

The LT4611 provides both a 10 GbE and 1GbE PTP interface and comes standard with three independent synchronized analog black and burst outputs. This overcomes the challenges of requiring both IP and SDI timing references. It also supports a stay-in-sync function which maintains the phase when GPS reference is lost, plus a slow-lock function to reduce quality-of-service issues that occur when genlock is restored.

The new instrument is supported by three LT4610-compatible hardware options and four LT4611-specific hardware options which can be selected to suit current operating environments.

There is level and then there is loudness. Neither can be measured absolutely, but by adopting standardized approaches it is possible to have measurements that are useful.

Audio Levels - Part 4

There are two basic reasons to know the level of an audio signal. One of these is more technical and one of them is more subjective.

Audio Levels - Part 3

The traditional level standards were based on electrical signals of specified power. When these signals are recorded on media, or transmitted in other ways, these definitions no longer apply.
