英文簡介：
Agilent 3458A
Agilent-Hp 3458A Multimeter

The 3458A Multimeter is among the fastest, most flexible and accurate multimeters offered by HP, and includes such features as 8 digit resolution. DC voltage is from 0.1 V to 1000 V with and accuracy of 0.6 ppm, and AC voltage range is 10 mV to 1000 V with an accuracy of 100 ppm. Resistance range is from 10 ohms to 1 Gohms with an accuracy of 2.2 ppm. The 3458A also measures AC and DC current at high accuracy and has a built-in frequency counter to 10MHz.

The HP 3458A multimeter shatters longstanding performance barriers of speed and accuracy on the production test floor, in research and development, and in the calibration lab. In your system or on the bench, the HP 3458A saves you time and money with unprecedented test system throughput and accuracy, seven function measurement flexibility, and low cost of ownership. Select a rate of 100,00 readings per second for maximal test throughput. Or achieve highest levels of precision with up to 8.5 digits of measurement resolution and 0.1 part per million transfer accuracy.
Add to this the 3458A‘s simplicity of operation, and you have the ideal multimeter for your most demanding applications.
