Thermistor power meter power absorbed M3-22
Also, this can be called a power meter: M322, M3 22.
M3-22 wattmeter absorbed power thermistor is designed to measure sinusoidal microwave signal and the mean power of pulse-modulated microwave signals in coaxial and waveguide paths.
Power Meter M3-22 consists of a measuring unit and a set of thermistor transducers.
Scale - vertical.
Wattmeters have access to the recorder.
Measurement range of capacities - from 6 mW to 6000 mW to within 12 mW, 30 mW, 60 mW, 120 mW, 300 mW, 600 mW, 1200 mW, 3000 mW, 6000 mW.
Frequency - 0.15 GHz to 78.3 GHz.
Thermistor resistance DC - 50 ohms, 75 ohms, 100 ohms, 200 ohms, 240 ohms, 330 ohms, 400 ohms.
RF coaxial tract - 75 ohms, 50 ohms.
RF waveguide path - 17h8 mm 35h15 mm 28,5 x12, 6 mm; 23h10 mm 11h5, 5 mm, 7.2 x 3, 4 mm, 5.2 x2, 6 mm, x1 3.5, 8 mm.
Instability of wattmeter M3-22 time in the steady thermal mode in 30 seconds - no more than 0.5 mW.
Warm-up time after turning on the meter:
- At the upper limits 1200 mW, 3000 mW, 6000 mW - 0.5 h;
- The remaining range - 2 hours
Overall dimensions of the measuring unit - 530x325x375 mm.
Mass M3-22 - 26 kg.
Operating Conditions Power Meters M3-22:
Operating temperature - from +5 ° C to +40 ° C.
Relative humidity at +30 ° C - from 90% to 95%.
