ALEXA SXT W机型概况 ALEXA SXT W基于大受欢迎的ALEXA SXT Plus所打造，它将替代之前ALEXA SXT Plus和ALEXA SXT Studio机型。和过去一样，ARRI依然为现有的ALEXA SXT EV和ALEXA SXT Plus机主提供了高性价比的升级选项。
伴随着新硬件的发布，SXT平台软件系统也升级到了2.0版本。SXT SUP 2.0改善了HDR监看性能，支持现有的SxS PRO+和CFast 2.0存储卡，抓帧更快，新加入许多WCU-4和镜头马达功能并做出一系列精细改进。 与挂载外置发射装置相比，内建视频发射器的ALEXA SXT W让摄影机系统更加紧凑、轻便，同时也意味着机身四周的线缆更少，附件出故障的机率更低了，因为在工作现场最常见的故障基本都是线缆导致的。无线功能令配置启用摄影机更加快捷，移动更加迅速。 让摄影团队最头痛的是摄影机不同无线电频率之间的干扰，解决这些意外费时费力。ARRI无线视频系统消除了这些隐患，因为它能够与ALEXA SXT的其它无线电设备：WiFi和ECS（ARRI专有的摄影机与镜头控制系统）天衣无缝地配合工作。 另外，ALEXA SXT W集成的WiFi组件带来一系列新的特性，例如在现场无线管理色彩，或是通过ALEXA网页遥控功能无线控制摄影机，还有更多强大的WiFi功能正在紧锣密鼓地开发。 在ALEXA SXT平台上直接内建无线视频发射器是一次意义重大的升级，它展现了ARRI持续投入研发，强化SXT平台的决心。 •完全无线的摄影机 - 集成无线视频 - 集成WiFi - 集成ARRI ECS系统，无线控制摄影机和镜头 - 无线视频、WiFi和ECS信号互不干扰 •替代SXT Plus和SXT Studio机型 - SXT W基于成功的ALEXA SXT Plus机型打造 - “W”代表“无线（Wireless）” •集成无线视频 - 比安装外置发射器更小巧轻便 - 杜绝线缆故障 - 安装更快捷 •集成WiFi - 无线控制画面风格 - 无线控制摄影机 - 更多功能开发中 •SXT是ARRI重点打造的平台 - 为老机型提供极具吸引力的升级方案 ARRI无线视频系统（WVS） ALEXA SXT W搭配一套全新的完整ARRI无线视频系统，再配合一个独立的视频发射器，它能够兼容其它的ARRI或是第三方厂商的摄影机，另外还有一个独立的视频接收器，能够接收来自发射器的信号。 丰富的附件设备包括有安装支架、延长天线、手持使用的导演监视器支架（DMS-1）以及针对ARRI发射器专门改造的内建接收器的Transvideo监视器，不管您是使用这一款还是其它型号的监视器，模块化的系统安装起来都非常紧凑与便捷。视频接收器上设计有一路额外的电源输出，这样只使用一块机载电池就能同时为接收器和手持监视器供电。因为设计了更高的输入电压范围，用户选择电池的空间更大。 来自ALEXA SXT W和独立的无线视频发射器的无线视频信号发射距离长、无压缩，为了安全起见已经过加密，设备之间无线连接稳定可靠，能够迅速重连。音频、时间码和REC旗标也包含在这些零延迟的信号中，每一台发射器最多同时支持4台接收器。 对于导演、摄影师、助理或在现场的其它工作人员来说，告别机身四周繁杂的线缆，直接从ARRI无线视频系统接收监视信号提升了创作过程的控制力与大局观，降低了团队成员的工作难度。从小小的接口保护盖到式样丰富的安装方式，ARRI的工程师与专家们在这套系统的人体工学与耐用度上倾注大量心血，参考专业制作现场的真实使用环境，所有组件都设计成防泼溅、防尘并且采用坚固耐用的材料制造，适应大范围的工作环境温度变化。所有的设备采用完全相同的操控模式，安装起来十分快捷，配对过程已经简单到一键即可完成。 和所有的ARRI产品一样，ARRI遍布全球的服务中心随时为ALEXA SXT W提供完善的服务支持。 •一套完整的系统 - ALEXA SXT W - 无线视频发射器（WVT-1） - 无线视频接收器（WVR-1） - 适用于Gold和V型接口电池的电池转接笼（BAC-G, BAC-V） - 导演的监视器支架，最多可同时安装两台监视器（DMS-1） - Transvideo Starlite ARRI-WVS监视器 - 天线延长臂（AEB-1） - 安装支架和电缆

ALEXA SXT W - A Fully Wireless Camera In a move that will increase efficiency on set, ARRI has integrated a high-quality and low-latency HD video transmitter and WiFi into the new ALEXA SXT W model ("W" for Wireless). This article provides you a complete introduction to the ALEXA SXT W camera, by explaining the following parts:
ALEXA SXT W Overview Based on the popular ALEXA SXT Plus, the SXT W will replace the SXT Plus and Studio models. As always, there are attractive upgrade options for existing owners of ALEXA SXT EV and ALEXA SXT Plus cameras.
The new hardware will be accompanied by software upgrade SXT SUP 2.0, which adds improved HDR monitoring, support for current SxS PRO+ and CFast 2.0 cards, quicker frame grabs, various WCU-4 and lens motor features, and other refinements. Having a video transmitter built into the ALEXA SXT W makes the camera smaller and lighter than it would be with an external transmitter. It also means fewer cables around the camera and fewer associated problems, since cable failure is by far the most common technical hitch on set. Camera setup and power-up will be quicker, and productions will be able to move faster. Interference between different radio frequencies can be a time-consuming issue for camera crews. The ARRI Wireless Video System eliminates this issue because it works harmoniously with ALEXA SXT W’s other radio-based offerings: the WiFi and the ECS, ARRI’s proprietary camera and lens control system. In addition, the integrated WiFi radio opens up a whole range of options, starting with wireless look control on set and continuing with wireless camera remote control using the ALEXA Web Remote. Other exciting WiFi options are currently under development. The introduction of a built-in wireless video transmitter is a significant upgrade for the ALEXA SXT and reflects ARRI’s commitment to continually improve the SXT platform with additional functionality. •A fully wireless camera - Integrated wireless video - Integrated WiFi - Integrated ARRI ECS wireless camera/lens control - Interference-free operation between video, WiFi and ECS radios •Replaces SXT Plus and SXT Studio - SXT W is based on popular ALEXA SXT Plus - "W" stands for Wireless •Integrated wireless video - Smaller & lighter than with external transmitter - No cable problems - Faster setup •Integrated WiFi - Wireless look control - Wireless camera control - More features in development •ARRI is committed to the SXT platform - Attractive upgrades available ARRI Wireless Video System (WVS) The ALEXA SXT W forms part of a new and complete ARRI Wireless Video System (WVS), along with a stand-alone video transmitter for use with other ARRI or third-party cameras, and a stand-alone video receiver that picks up signals from either transmitter. An extensive accessory range includes various mounting brackets, antenna extensions and the handheld Director’s Monitor Support (DMS-1), as well as a specially adapted Transvideo monitor with a built-in receiver for the ARRI transmitters. Whether using this monitor or others, the modular system allows for a compact and efficient setup. An extra power-out on the video receiver, for example, permits a single on-board battery to power both the receiver and an attached handheld monitor. A higher input voltage range allows more flexibility on battery choice. The high-performance video transmission from the ALEXA SXT W and stand-alone transmitters provide a robust radio link and fast re-link with a long-range, uncompressed and encrypted signal for safety. Audio, timecode and REC flag are included in the zero-delay signal, and up to four receivers can be used per transmitter. For the director, cinematographer, assistant or anyone else on set, a monitor feed from the ARRI Wireless Video System increases creative control and oversight without adding clutter to the camera configuration or potential difficulties for the crew. From the protective collars on the connectors to the versatile mounting options, all of ARRI’s expertise has gone into the ergonomics and durability of the system. Designed for real-world usage on professional sets, every component is spray and dust proof, constructed from rugged materials, and has a wide operating temperature range. All units share the same operating controls, making set up a snap, and the pairing procedure has been simplified with a single button. As with any ARRI product, it is backed up by ARRI's extensive network of service stations across the globe. •A complete system - ALEXA SXT W - Wireless Video Transmitter (WVT-1) - Wireless Video Receiver (WVR-1) - Battery Adapter Cages for Gold and V mount (BAC-G, BAC-V) - Director's Monitor Support for one or two monitors (DMS-1) - Transvideo Starlite ARRI-WVS monitor - Antenna Extension Bracket (AEB-1) - Mounting brackets and power cables

Up to four receivers (either WVR-1 or Starlite ARRI-WVS) can be used per transmitter and four to six transmitter/receiver groups can be used on the same set. Here is a sample setup with three cameras.
