Measuring interference P4-12A (P-4-12A, P 4-12A.)
P4-12A meter - a device designed to measure and find interference and measuring the high-frequency voltage at the output terminals of the source of interference and intensity of high-frequency fields, for which the instrument given a whip antenna with 1m (AA = 0.5 m).
- From 10mkV 30 000mkV in the frequency range from 0.15 MHz to 12.5 MHz;
- From 30mkV to 100,000 microvolts over the frequency range from 12.5 MHz to 30 MHz.
The bandwidth of 9 kHz.
Power supply 12V battery.
