Its frequency range is 500kHz ~ 5MHz, which is mainly used to measure the field strength of medium wave, and the measurement accuracy can be up to + 1dB. The machine adopts the electronic tuner of the local oscillator frequency synthesizer, which can be automatically tested by CPU control. It can also be tweaked by a rotary encoder under manual conditions. Since the measurement results are automatically calculated to print out the output, it is also suitable for the attenuation investigation of the radio waves and the continuous monitoring record. In addition, the machine holds various installers, which can provide the software according to the requirement because of the automatic testing system that can be programmed to meet the purpose of the gp-ib interface. The standard equipment for the power supply is the dry battery driver, which is equipped with AC adapter and battery pack (rechargeable battery and charger).

Features:

There is an automatic level correction function, which can be done correctly and quickly.

Automatic determination.

The measurement results are automatically performed by the LCD display.

It can also print out the output.

The gp-ib interface can be programmed for various automatic test systems.

For example, the antenna is used to determine the antenna and antenna system.

The number is automatically calculated as a field strength and can be read directly.

The number of random frequencies and up to 100 measurement conditions can be stored.

Scanning can be done in two ways: search and storage.

Different groups can store scanning and periodic storage scanning.

Small size lightweight for mobile measurement.
