Intelligent microwave frequency counter considerations

Intelligent Microwave Frequency Counter Model: HA3382A

Product Details:

The HA3382A series microwave frequency counter uses microwave sampling technology to realize the measurement of microwave. The function control, measurement timing and data processing of the whole measurement process are all completed by the internal microprocessor. It is a new generation of intelligent microwave frequency measuring instrument. . The instrument adopts medium-large scale integrated circuit and some single-chip integrated circuits with excellent performance, which makes the design of the instrument more reasonable, low power consumption and high reliability. The average fault-free time of the whole machine is more than 8000 hours. The instrument has the characteristics of wide frequency measuring range, high sensitivity, large dynamic range, high precision and convenient use, and meets the requirements of microwave frequency measurement in the fields of national defense, scientific research and electronic product production.

Features:

The instrument line and structure design is reasonable, compact, low power consumption, high reliability, and the average trouble-free working time of the whole machine is more than 8000 hours.

The utility model has the advantages of wide frequency measuring range, high sensitivity, large dynamic range, high precision, high speed, small volume, convenient use of the words, high performance and price ratio.

The use of the conductive rubber process makes the instrument more beautiful and generous in structure and more convenient to use.

It adopts 3.5-inch QVGA color liquid crystal display technology, and each measurement parameter has clear data and long service life.

With manual mode for quick measurements.

The low frequency range has a 10-bit high resolution measurement method.

Intelligent interface, the instrument is equipped with RS232 interface (optional USB, GP-IB interface), realizes connection and management with computer, and can be remotely controlled to form an automated test system to realize unattended monitoring to meet the needs of different users. demand.
