Wattmeter M3-21A (M321A, M-3-21A, M 3 21A, M3 21A)
 
Wattmeter M3-21A is designed for continuous measurement of power fluctuations and the average power of pulse-modulated microwave signals, complete with a foster thermoelectric converter M5-78.
 
Technical characteristics of the devices wattmeters M3-21A:
 
Frequency range - 0.1 GHz-12 42GGts;
The range of measured capacity - 0.01 mW, 10 mW at the limits of measurement of 0.03 mW and 0.1 mW, 0.3 mW, 1 mW, 3 MW, 10 mW;
Characteristic impedance power meter - 50 ohms;
Power meter has an input connector III (male);
Standing wave ratio (KstU) device power meter M3-21A no more than:
- 1.35 - in the range from 0.1 GHz to 4.0 GHz;
- 1.40 - over the range 4.0 GHz to 10.0 GHz;
- 1.50 - over the range 10.0 GHz to 12.42 GHz.
The main error of the instrument wattmeter M3-21A absorbed power without error due to inconsistency of its input and taking into account given in the form of amendments to the transmitter on the frequency dependence of the coefficient of efficiency (CE) does not exceed the values ​​defined by the formula:
d = ± (1 10 mW / Px ∙ 100)%
where P - power meter indications, mW;
