HP4193A頻譜分析儀中文簡介：
      該儀器是矢量阻抗測量儀，測量從10兆歐姆到120千歐阻抗的幅值和相位為-180.0至+180.0。內部振蕩器提供從400kHz到110MHz的測試信號。該測試信號是在10 A之間的恒定的電流，根據阻抗范圍（10歐姆，100歐姆，5范圍）。 4193A的功能測試組件在電路和輸出電路和標準的HP-IB和模擬輸出。其他功能還包括自動，保持，手動范圍控制和31/2-DIGIT顯示。

英文簡介：
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.
