产品详情
矢量网络分析仪 (VNA) 是一种电气测试仪器，它使用已知的连续波 (CW) 信号来测量射频 (RF) 和微波器件、系统和子系统在设计和制造应用中的幅度和相位响应。它是帮助制造无线设备的重要测试工具。
泰克 TTR500 系列双端口双路径矢量网络分析仪让射频设计和验证工程师、教育专业人员和制造组织能够通过减少原型迭代和准确可靠地进行日常测量来缩短产品上市时间。

矢量网络分析仪优势
VNA 允许您以其他测试仪器不支持的方式测量诸如反射系数、阻抗、导纳、回波损耗、插入损耗、增益、隔离等复量。
传统的测试设备（如功率计、频谱分析仪和示波器）通常只有接收器用于测量被测器件 (DUT) 发射或创建的信号。而 VNA 则不同，它同时具有一个信号源和一组接收器，用于确定由 DUT 引起的激励变化。基于激励的测试方法允许 VNA 测量非常小的反射和激励的变化，使您能够在真实环境和测试条件下准确检定任何射频器件。

独特创新，降低成本并减小尺寸
TTR500 系列矢量网络分析仪将六个 RF 接收器和两个射频信号源紧密集成到一个专有 ASIC 中。 凭借创新型架构和专利技术，TTR500 系列矢量网络分析仪具有可媲美台式矢量网络分析仪的性能水平，但成本即降低了 40%，而且其尺寸和重量仅为同等性能设备的七分之一。
Benchtop performance at a fraction of the cost
The TTR500 offers industry-leading price and performance. With more than 122 dB dynamic range and less than 0.008 dB RMS trace noise, the TTR500 has performance similar to expensive, conventional benchtop VNAs.
Compact and transportable: Take test where you need it
Gone are the days when you had to roll a cart with a heavy, shared VNA. Weighing under 3.5 lbs (1.59 kg), the TTR500 has a form factor small enough to fit in a briefcase. With a price tag to match, you can put a VNA on every engineering bench to improve efficiency and uptime. In a classroom, students can get hands-on experience with industry standard test instrumentation.
Performance, size, reliability, affordability - choose four
The TTR500A series VNA includes an impressive array of technological and patented advances that allowed us to bend many of the traditional trade-offs between RF performance, size, reliability, and cost.
Performance: Inside the VNA is a tightly integrated, single-board design. At its core lies a proprietary ASIC that implements all of the transmitting and receiving functions. Along with decades of experience in RF front-end and shielding design, this integration allowed us to implement advanced DSP and patented error correction techniques that dramatically improve measurement accuracy and dynamic range.
Convenience: Traditional benchtop VNAs have a computer inside that typically becomes obsolete by the time the product hits the market. Our architecture enables significant improvements in size, cost, and reliability by communicating over USB to your PC, while adding additional benefits and convenience. For example, run VectorVu-PC with other applications, share data seamlessly, and save individual application setups on your PC when multiple users share the TTR500.
Size: A compact single-board design without heavy input and display components allows the TTR500 to pack a lot of powerful functionality in a tablet-sized frame. Store it in a drawer, pack it in your briefcase, or carry it on a plane. Take quality test and measurement technology wherever you need it.
Reliability: In addition to reduced part count, integration on a singleboard consumes less energy than traditional benchtop VNAs. The board generates less heat, resulting in lower component stresses and higher reliability. A fanless design provides a quieter operation. We back all of this with a three year warranty.
Affordability: With fewer parts and an integrated design, we created a handheld VNA that delivers traditional benchtop performance and convenience at an unrivaled price. Why settle for less?
Integrated bias tee for active devices
Use the built-in bias tee (standard in both models) to provide a DC bias to active devices without the expense and complication of external circuitry. Power the bias tee directly through BNC connectors on the rear panel.
Complete line of affordable accessories
To simplify shopping for the complete VNA solution, Tektronix offers a range of accessories for high-accuracy measurements. Select from calibration kits, phase-stable cables, adapters, attenuators, rackmount, rugged carry case, and a training kit. See Ordering Information for a full list of available accessories.
Full 2-port 2-path S-parameter measurements
An independent RF source and three RF receivers for each port of the TTR500 enable you to take high-accuracy magnitude and phase measurements with a 1-port or 2-port device under test (DUT). Use the TTR500 to perform complete S11, S12, S21, and S22measurements of the DUT and display data in a variety of formats (see measurement functionality table).
