Product Description
Microwave Power Meter/Frequency Meter
2438 series microwave power meter consists of a main unit of microwave power meter and a series of microwave power sensors. In the design, broadband diode detector, digital signal processing technology and multidimensional calibration compensation technology are adopted to make the instrument have wide frequency band, wide dynamic range, high accuracy, fast measurement and analysis, sensor serialization, convenient use and so on. It is mainly used for measuring and calibrating the average power, peak power and pulse envelope power of microwave signals. It is an important measurement instrument for R&D, production, acceptance and maintenance in communications and other fields.
Features
Multi- measurement mode
CW measurement, peak measurement, CCDF statistic measurement
CW power sensor frequency up to 500GHz
Max. dynamic range: 90dB
When the peak power sensor is connected, it becomes high-performance peak power meter. The amplitude and time domain parameters of pulse modulated signals in 50MHz ~ 67GHz band can be measured and analyzed.
Frequency response offset for high power measurement
This function is very useful when storing high-power directional coupler or high-power attenuator for high frequency signal measurement. After starting the frequency response offset function, the power meter automatically sets the calibration factor according to the calibration form of the sensor and the frequency response offset form in the process of automatic calibration and power measurement, and corrects the measurement results to ensure the measurement accuracy.
Save and recall configuration information
In order to reduce the duplication process, the user can save up to 10 configuration information of the power meter host. These configuration parameters are stored in the system, and the user can make a convenient call when conducting similar measurements.
