Tho following information is directly from Hewlett-Packard Test and Measurement Catalog The HP 4191A permits reliable measurements over a widemeasuring range. Its outstanding repeatability, frequency response and accuracy are made possible by unique error correction capability and specially designed test fixtures. Its unique features permit very wide applications in: (1) semiconductor testing such as surface state evaluation at high frequencies and the input/output impedance evaluation of diodes and transistors; (2) resonator, filter, and magnetic and dielectric materials testing; (3) evaluation of LCR components such as high frequency chip and leaded components; and (4) testing of communications related components such as cables, connectors, etc. Parameters Measured: |Z| - q, |Y| - q, vector reflection coefficient - q , R - X, G -B, vector reflection coefficient (real/imaginary components), L - R . G . D . Q, C - R . G . D . Q. Display: 4½ digit, max. display 19999 counts. Deviation Measurement (deviation from stored reference): - 19999 to + 19999 counts; -1999.9 to + 19999.9%. * Frequency Range: 1 MHz to 1000 MHz * Frequency Step: 100 kHz, 1 to 500 MHz; 200 kHz, 500 to 1000 MHz Signal Level: (into 50 ohms): -20 ± 3 dBm. Frequency Control: Spot and sweep. * Spot Measurement: At specific frequency ( or dc bias). * Swept Measurement: Manual or automatic sweep from start to stop frequency ( or dc bias) at step frequency ( or dc bias) rate in linear or logarithmic form. Auto Calibration: Automatic error compensation referenced to connected terminations (0 ohms, 50 ohms, 0 S), 51 frequencies including start and stop frequencies. Electrical Length Compensation: Automatic compensation for electrical length of test fixtures (range: 0 to 99.99 cm). * Voltage Range: -40 to +40 V, 10 mV step * Bias Control: spot and swept * Max Allowable Current: 100 mA Key Status Memory: Two sets of measuring conditions can be stored and recalled at any time. Trigger: Internal, External, or Manual HP-IB Data Output and Remote Control: Standard Some examples of cheapest rate freight (4-5 days): (Hp 4191A rf impedance analyzer, nice & working was posted and is owned by: Arnold Walters) |
