    • Systems and methods for testing a device under test (DUT) that includes a low power output driver. The methods include providing an input signal to the DUT. The low power output driver is configured to generate a data signal responsive to receipt of the input signal by the DUT and provide the data signal to a signal analyzer via a data signal transmission line. The methods further include determining an expected data signal to be received from the low power output driver and charging at least a portion of the data signal transmission line with a co-drive output signal that is based, at least in part, on the expected data signal. The methods further include receiving a composite data signal with the signal analyzer. The systems include probe heads with a plurality of data signal transmission lines and a plurality of co-drive conductors.
    • 用于测试包含低功率输出驱动器的被测设备(DUT)的系统和方法。 所述方法包括向DUT提供输入信号。 低功率输出驱动器被配置为响应于DUT接收到输入信号而生成数据信号,并且经由数据信号传输线将数据信号提供给信号分析器。 所述方法还包括确定要从低功率输出驱动器接收的期望数据信号,并且至少部分地基于预期数据对共驱动输出信号进行数据信号传输线的至少一部分的充电 信号。 所述方法还包括用信号分析器接收复合数据信号。 该系统包括具有多个数据信号传输线和多个共驱动导体的探头。
