【应用】神奇InfiniiVision X系列示波器两步即可搞定PSRR测量!
引言
测试和表征电源时,最主要的测量工具是示波器。目前有许多示波器(包括KEYSIGHT InfiniiVision X 系列)可以提供特殊的功率测量选件,以帮助工程师自动实施最重要的测量。图 1 显示的是电源表征测量列表。配有功率测量选件(DSOX3PWR或DSOX4PWR)的Keysight InfiniiVision 3000T和4000X系列示波器都可以提供这一列表。频率响应测量是是德科技仪器的独有测量功能,包括电源抑制比(PSRR)和控制环路响应(波特图)。这些特殊的激励响应型测量通常使用低频网络分析仪来实施。但是由于 Keysight InfiniiVision X 系列示波器配有内置的函数 / 任意波形发生器,所以也能执行这些测量。

电源抑制比(PSRR)
图2为PSRR测试装置的结构图。这种测试可以测量供电器件(例如线性稳压器(LDO))能在多大程度上抑制被测器件直流输入端口注入的各个频率分量。或者说,在直流输入端注入的干扰信号有多少能够到达经过稳压的直流输出端。
要执行PSRR测试,必须在直流输入端注入正弦波,然后从低到高执行频率扫描。这一测量还需要使用DC+AC网络求和器件。测量系统测量经调制的输入和输出交流电压,然后计算扫描频段内每个频点的抑制比20Log(Vin/Vout)。有些工程师认为公式应为20Log(Vout/Vin)。但这个公式应该是用于计算增益(A)而不是抑制比。抑制比是增益的倒数。Keysight InfiniiVision X系列示波器内置的波形发生器和功率测量选件使示波器首次能够执行此类频率响应测量。

探测输入和输出
虽然可以使用标准的10:1无源探头来探测调制后的直流输入,但在输出端还必须使用1:1无源探头。假设被测的LDO有很高的抑制比,所以输出的幅度将非常小(不到几mV)。另外将直流输出测试点附近的探头正确接地至关重要。如果您使用1:1无源探头标配的接地线,它将起到天线的作用,并在空中捕获大量噪声,这会减小您的测量的动态范围。一个短弹簧夹具接地适配器(通常作为探头附件一起提供,外形见图3插图),尤其是焊入式探头插座将提供最好的低噪声信号完整性。
图3中的照片显示了在对线路稳压器测试板实施PSRR测量时所使用的实际测试装置,请注意在输出探测点上使用的探头插座,它可以建立可靠的接地连接(没有天线效应!)。

执行电源抑制比(PSRR)测量
在完成与被测器件的所有连接后,首先在功率分析(Power Analysis)菜单中选择PSRR测量。然后在信号(Signals)子菜单中,定义使用哪些示波器通道来探测输入和输出。例如,输入=通道1,输出=通道-2。接下来,选择设置(Settings)子菜单并定义测试参数,例如起始频率(Start Frequency)、终止频率(Stop Frequency)和WaveGen幅度(amplitude)。虽然输入干扰信号的幅度越高,动态范围测量结果就越高,但是如果幅度设置得太高,可能就会产生非线性失真。在设置(Settings)菜单中,您还可以定义最大Plot率(dB)。虽然默认设置为100 dB,但是示波器没有这么大的动态范围。
要开始PSRR测量,只需点击应用(Apply)键。在这个每次扫描测试过程中,示波器在WaveGen信号上内部触发,以实现非常稳定的触发。在每个被测频率上,示波器都会自动优化输入和输出波形的垂直标度,并在每个频率上执行8次平均,以去除随机噪声并提供最大的动态范围。对于PSRR很高的被测器件,测量得到的输出信号的幅度往往不到1 mV,被示波器的本底噪声所掩盖。随着测试的进行,示波器在显示屏幕上绘制出PSRR结果。
图4显示了PSRR测量的结果。黄色轨迹为输入电压波形(通道1),绿色轨迹为最终被测频率(20 MHz)上的输出电压(通道2)。您可以看到,输出幅度低于 1 mVpp。 紫色轨迹为PSRR图。此测试使用100 Hz 至 20 MHz的扫描频率,输入干扰信号的幅度为 350 mVpp。抑制比在24 kHz上达到最大值,大约为68.5 dB;在1.6 MHz附近最小,
仅为 39 dB。示波器的动态范围使其能够对低噪声输出器件(例如线性稳压器)执行高达 70 dB 的PSRR测量。

总结
示波器是目前工程师在测试和表征电源设计时使用的最主要测量工具。但是大多数示波器在执行频率响应测量――例如电源抑制比(PSRR)测量时都受到很大的限制。Keysight InfiniiVision X 系列示波器是市场上首款能够自动实施PSRR测量的示波器。尽管其测量动态范围和测量精度肯定比不上低频网络分析仪,但通常也足够满足需求了。
系统要求
在Keysight InfiniiVision 3000T、4000 或 6000X系列示波器上执行PSRR测试,要求示波器通过功率测量选件(DSOX3PWR、DSOX4PWR或DSOX6PWR)获得许可证。不需要WaveGen选件。示波器将自动启动WaveGen以执行一次性的PSRR测量。推荐使用1:1无源探头(例如N2870A)来探测小功率输出信号。输入干扰信号要想从示波器WaveGen输出端耦合至直流输入端,需要使用网络求和器件。
除了上面列出的最低系统要求之外,我们还推荐您的3000T或4000X系列示波器在4.05或更高版本的固件上运行。

如何抑制示波器和探头过冲和振铃?
示波器探头的重要性示波器探头是示波器外部的电路器件,其作用是从被测电路中探测信号,当探头接入被测电路后,探头会成为测试电路的一部分,而探头和示波器相连接,探头又会成为示波器测量系统的一部分。所以探头的电路设计非常重要。由于探头中存在分布电容和分布电感,尤其在进行高频信号测量的时候会使信号的频率特性变差。
