Power flux density meter PO-1
Also this device can be called: PO1, PO 1, P0-1, P-01, P 01.
PO-1 meter power flux density is used to measure the flux density of the radiation power UHF-SHF.
The composition of the meter PO-1 includes an antenna, battery pack, matching attenuator D2-9, the bridge to measure the power on thermistors M4-2, matched load E9-9.
Meters PO-1 is also equipped with a set of horn antennas (P6-17, P6-19, P6-20) and thermistor heads (M5-17, M5-19, M5-21, M5-22).
Operating frequency range - from 150 MHz to 10 GHz.
Range measurements M4-2 - from 0 to 150 mcW; from 0 to 500 mcW; from 0 to 5 mW, from 0 to 7,5 mW.
- M5-17 - from 200 cm to 10 cm;
- M5-19 - from 3.6 cm to 5,4 cm;
- M5-21 - from 2.1 cm to 2,6 cm;
- M5-22 - from 1.8 cm to 2,1 cm.
- frequency range - from 0,15 GHz to 2,7 GHz;
- VSWR - 1,5;
- power - 1W.
The wavelength of the fundamental radiation of the antenna:
- P6-17 - from 5,4 cm to 3,6 cm;
- P6-19 - from 11,1 cm to 8 cm;
- P6-20 - from 16,7 cm to 11 cm
E9-9 is a load resistance, absorbing power supplied to it.
Operating frequency range E9-9 - from 30 MHz to 1000 MHz.
Attenuation, insertion feeder and matching attenuator advance taken into account in the design PO-1. Measuring the flux density necessary to produce power at a maximum operating capacity of the emitting device with reduced or several times followed by multiplication of the measured power flux density in n times.
