The field strong instrument as the name suggests is the instrument that measures the strong field.The value of the strong instrument is μV/m as a unit, which has a length unit m.In principle, the voltage value of the level table (or voltage table) is at the input port of the instrument, and the voltage (or called the potential) of the measurement of the strong instrument is the voltage of an antenna in the air.Strictly speaking, the strong instrument is composed of level tables and antennas.

How to use the field strong instrument
① Correctly connect the cable, and the connection cable should not be too long.If it is not for long cables, you must add the cable loss to the readings of the instrument, especially the high frequency band.② Field strong instrument must not only measure the image carrier level, but also measure frequency sound -regulating sound radio signal carrier levels. Therefore, the signal level used should include the sound carrier wave electric and image carrier level.The level of sound loading is defined as the effective value of the sound carrier voltage at the 75Ω terminal without adjusting the sound carrier voltage.The image carrier level is defined as the valid value of the image carrier voltage at the package peak (synchronous head) at the 75Ω terminal, which is represented by DBμV.Therefore, the measurement detector of the image carrier level should be a peak detector, and pay attention when using it.③ Use environmental temperature.In the northern winter, you should pay attention to the insulation measures. The south of the summer should try to avoid placing the instrument directly under the sun, otherwise the reading error will greatly exceed the scope of the technical indicators.
