Multi- measurement mode
When the CW power sensor is connected, it becomes traditional CW power meter. The instrument can accurately measure the output power of micro-wave and millimeter wave with the frequency range of 9 KHz~500 GHz. The dynamic range of output power measurement can up to 90 dB with a single sensor.

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.

In the statistic measurement mode, the instrument does not need trigger events to measure, but can realize continuous sampling measurement of the signals. CCDF represents the percentage of a sample point in a specific sample that is greater than or equal to a specific value in the sample. It can also be represented as 1 minus CDF.

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.

Internal zero, fast calibration
The peak power sensor adopts internal zero calibration technology, which makes the peak power sensor automatic calibration speed very fast. In addition, it can be calibrated without leaving the measured parts, and the signal can be zeroed without interruption of the signal input.

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.

Programmable control
GPIB, LAN, USB control, for system construction.
