For order is possible effectively delivery of any quantity.
Wattmeter M3-75 (M375, M-3-75, M 3 75, M3 75)
Wattmeter M3-75 is designed to measure the mean power of continuous and pulse-modulated microwave signals in the regulation and verification of electronic equipment.
The devices can be used to measure the attenuation and losses in the paths, the power flux density, power level of instability, as well as in automated measuring systems.
The operation of the device and its components by microprocessor.
Technical characteristics of the devices M3-75 wattmeters:
Modes of operation of the device:
- Linear - measuring microwatts, milliwatts;
- Log - measuring in decibels relative to 1 mW;
- Relative logarithmic - measurements in decibels relative to a fixed level of capacity;
Frequency response unit wattmeter M3-75 - 37.5 GHz-178, 4 GHz;
Measurement range - 0,3 ∙ 10 -6 10 -2 W-W;
The receiving transducer device power meter M3-75:

The basic error of the measurement instrument wattmeter M3-75:
- Linear regime:
- ± 6% (with a PP-13 PP-14), ± 10% (PP-15 PP-16), within 100mkVt, 1 mW and 10mVi;
- ± [15 +0,25 (Pk/Px-1)] at the limit 10mkVt;
- ± [25 +0,4 (Pk/Px-1)] at the limit 1mkVt;
- Logarithmic mode - ± 0,3 dB (PP-13 PP-14), ± 0,45% (PP-15 PP-16) in the range 100mkVt, 1 mW and 10 mW;
The settling time of reading the power meter M3-75:
- At the limits of change and 1mkVt 10mkVt - 10s;
- In the range 100mkVt, 1 mW and 10 mW - 1 s;
Time saving calibration - 1:00;
The limiting value of volatility readings over time, including the "drift of the electrical zero", at a constant temperature under normal conditions in the steady state - 0.25 mW / min;
The manufacturer guarantees the quality of the unit absorbed power wattmeter M3-75 technical requirements specifications, subject to the consumer the terms and conditions of storage, transportation, installation, operation, established specifications and operational documentation.
