Detailed

S2438 series microwave power meter is composed of a host of microwave power meter and a series of microwave power sensors. New technologies such as broadband diode detection technology, digital signal processing technology and multi-dimensional calibration compensation technology are used in the design, making the instrument have a wide frequency band, large dynamic power range, high precision, fast measurement and analysis, serialization of sensors, and ease of use are all used to measure and measure the average power, peak power and pulse envelope power of microwave signals. It is an important measurement instrument for the research, production, acceptance and maintenance of radar, electronic countermeasures, and communications.


Main Functions

1. Multi-measurement mode to fit different measurement requirements

S2438 series microwave power meter has continuous wave measurement, peak measurement, CCDF statistical measurement three measurement modes. 

2. Set frequency response offset for accurate measurement of high power

This function stores the frequency response of high power directional couplers or high power attenuators for highpower signal measurements offset is very useful. After the frequency response bias function is activated, the powermeter automatically roots the system during automatic calibration and power measurement. According to the sensorcalibration table and frequency offset table, calibration factors are set to correct the measurement results to ensurethe measurement accuracy.

3. Quick calibration peak power sensor

The peak power sensor uses an internal zero calibration technique that makes the peak power sensor's auto-calibration extremely fast. In addition, calibration can be performed without leaving the device under test, andzero calibration can be performed without disconnecting the signal input. 

4. User statuses save/load

In order to reduce the repetitive setting process, the user can store configuration information for up to 10 statuses. These configuration parameters are saved in the system and can be easily invoked when the user makes similar measurements. 

5. Remote control mode

S2438 series microwave power meter supports remote control via GPIB, LAN and USB. Very convenient for user to build the measurement system.
