HP4193A频谱分析仪中文简介：
      该仪器是矢量阻抗测量仪，测量从10兆欧姆到120千欧阻抗的幅值和相位为-180.0至+180.0。内部振荡器提供从400kHz到110MHz的测试信号。该测试信号是在10 A之间的恒定的电流，根据阻抗范围（10欧姆，100欧姆，5范围）。 4193A的功能测试组件在电路和输出电路和标准的HP-IB和模拟输出。其他功能还包括自动，保持，手动范围控制和31/2-DIGIT显示。

英文简介：
HP4193A
The HP4193A Vector Impedance Meter measures impedance magnitude from 10 mohms to 120 kohms and phase from -180.0 to +180.0. An internal oscillator provides test signals from 400kHz to 110MHz. The test signal is constant current between 10 A, depending on impedance range (10 ohms-100 kohms, 5 ranges). The 4193A features test components in circuit and out-of-circuit and standard HP-IB and analog outputs. Other features include auto, hold, manual range control and a 3 1/2-digit display.
