VirtualProbe

• View signals where you cannot place a probe
• Model up to 6 circuit elements
• Remove probe loading
• De-embed fixtures
• Emulate modeled channels
• Multi-lane compatible
  • Configure up to 4 independent circuits models
  • With CrossLinQ and CompleteLinQ products, model crosstalk between multiple lanes
• Model crosstalk with 8 and 12-port S-parameters
• Included in CompleteLinQ product for signal integrity analysis
• Two ways to use: Independently, or within SDAIII

The VirtualProbe package expands the de-embedding and emulation capabilities of EyeDoctorII. Configure a multi-block circuit using S-parameters, and VirtualProbe will build the transfer function that returns the signal as it would appear before or after any block in the circuit.

Model your circuit as either a single-ended or differential lane, and configure a model using up to 6 blocks with S-parameters and transmission lines.

It is law of physics that you cannot make a measurement without disturbing the system. VirtualProbe removes probe loading effects from your measurement, further increasing your measurement accuracy.

Remove the effects of fixtures from the measured waveform to improve eye and jitter measurement accuracy.

Enhance your understanding of the behavior of channels that are still in the design stage by configuring VirtualProbe for emulation using your S-parameter models or measurements.

VirtualProbe is architected to meet the needs of engineers designing and testing multi-lane systems. Users can configure circuit models on up to 4 lanes, and use the "Xtalk" block to model crosstalk.

Model crosstalk between lanes in multi-lane transmission systems with 8 and 12 port S-parameters measured with the Teledyne Teledyne LeCroy SPARQ or other VNA

VirtualProbe is included as a part of the CompleteLinQ product, allowing users to analyze virtually probed measurements, forming eye diagrams and measuring jitter, noise and crosstalk.

查看无法放置探头的信号

这个 VirtualProbe 软件包扩展了 EyeDoctorII 的去嵌入和仿真功能。使用 S 参数配置多块电路，以及 VirtualProbe 将构建返回信号的传递函数，就像它出现在电路中任何块之前或之后一样。

建模多达 6 个电路元件

将您的电路建模为单端或差分通道，并使用多达 6 个带有 S 参数和传输线的模块来配置模型。

移除探针加载效应

物理定律是，您无法在不干扰系统的情况下进行测量。 VirtualProbe 从您的测量中消除探头负载影响，进一步提高您的测量精度。

去嵌入夹具

从测量波形中消除夹具的影响，以提高眼图和抖动测量精度。

模拟建模通道

通过配置VirtualProbe 增强您对仍处于设计阶段的通道行为的理解，该设置使用您的 S 参数模型或测量进行仿真。

多通道兼容

VirtualProbe 旨在满足工程师设计和测试多通道系统的需求。 用户最多可以在 4 条通道上配置电路模型，并使用“Xtalk”块对串扰进行建模。

具有 8 和 12 端口 S 参数的模型串扰

使用 Teledyne LeCroy SPARQ 或其他 VNA 测量具有 8 和 12 端口 S 参数的多通道传输系统中通道之间的模型串扰

包含在用于信号完整性分析的 CompleteLinQ 产品中

VirtualProbe 作为 CompleteLinQ 产品的一部分包含在内，允许用户分析虚拟探测的测量结果，形成眼图并测量抖动、噪声和串扰。
