Microwave Power Meter TW2400

 

Product Overview :

 

Techwin Microwave Power Meter TW2400 is composed of microwave power meter main unit and serial power sensor, adopting embedded computer and embedded operating system integrally with application of microwave diode detection technology, digital signal processing technology and multidimensional compensation technology, which offer the instrument such characteristics as broad frequency band, large dynamic power range, sensor serialization, high precision, quick measurement and analysis and convenient operation. It is mainly used for the measurement and metering of average power, peak power and pulse envelope power of microwave signal, and also can be used for the measurement of high-power pulse modulation signal and narrow pulse modulation signal. It is an important measuring instrument for development, production, acceptance and maintenance in the fields of radar, electronic countermeasure and communication.

 

Main Features:

 

  • With accurate power measurement function of continuous wave signal, single sensor in dynamic range of 85 dB;
  • Available in measurement and analysis functions of various envelope parameters of microwave and millimeter wave pulse modulation signal, such as: peak power, pulse power, average power, overshoot, rise time, fall time, top amplitude, bottom amplitude, pulse width, pulse period, duty ratio, closing time and pulse repetition frequency;
  • Offering extended measurement function of high-power pulse if provided with high-power attenuator or high-power directional coupler to offer;
  • Available in automatic offset calibration function;
  • Available in automatic capture measurement function;
  • Available in rise/fall edge trigger and internal/external trigger function;
  • Available in CCDF statistical measurement and analysis function;
  • With color LCD display and Chinese/English graphical operation interface, for user’s convenience;
  • Available in storage/recall function;
  • With GPIB and LAN program control function to meet modern communication needs.

Multiple measurement modes to meet different user’s measurement requirements

Available in continuous wave measurement, peak value measurement and CCDF statistical measurement, three measurement modes. This instrument becomes a traditional continuous wave power meter if provide with continuous wave power sensor, which can measure the power of microwave and millimeter wave and continuous wave signals accurately, with single sensor in dynamic power measurement range up to 85dBm (-65dBm~+20dBm).

 

This instrument becomes a high-performance peak power meter if provided with peak power sensor, which can measure and analyze the amplitude and time domain parameters of pulse modulation signal.In statistical measurement mode, the instrument performs continuous sampling measurement on signal rather than trigger event. CCDF refers to the percentage of sampling point, the power level of which is above or equivalent to certain value, among whole samples, it can also be represented as 1-CDF (1 minus CDF).

Narrow pulse testing

TW2400 is capable of measuring and analyzing microwave and millimeter wave pulse modulation signal with pulse width of =50ns, and measuring and analyzing pulse modulation signal with duty ratio of less than one ten-thousandth.

Set frequency response offset

Frequency response offset which varies with frequency provides a quick and effective compensation method for relevant frequency changes in testing system response, acting on the power sensor. Power meter can store 10 frequency response offset tables, with maximum 80 frequency points each, which is very helpful for storing frequency response offset when measuring high-power signal of high-power directional coupler or high-power attenuator. After starting frequency response offset functioning, in the process of automatic calibration and power measurement, the power meter automatically sets calibration factor according to sensor calibration table and frequency response offset table, to correct the measurement results and ensure measurement accuracy.

Storage and recall of configuration data

In order to reduce repeated setting, user can store configuration data up to 10 types of power meter main unit. Those configuration parameters are saved in system for convenient recall by user during similar measurement.

Network program control

In addition to traditional GPIB program control function, TW2400 also has the function of network program control to meet the modern instrument testing requirements

Typical Applications:

Techwin microwave power meter TW2400 is a universal high-performance measurement instrument for peak microwave power, mainly used for measuring and metering average power, peak power and pulse envelope power of microwave signal, and also can be used for the measurement of high-power pulse modulation signal and narrow pulse modulation signal.
In continuous wave mode, it is a universal traditional microwave power meter;
In peak value measurement mode, through different timebase settings, the instrument can automatically measure and analyze the peak value power, pulse power, average power, overshoot, rise time, fall time, top amplitude, bottom amplitude, pulse width, pulse period, duty ratio, closing time and pulse repetition frequency, etc. multiple envelope parameters of microwave and millimeter wave pulse modulation signal.
