LF 10 Hz ... 100 kHz
HF 1.6... 470 MHz
5. Non-linear distortion factor meter
Frequency band 200 Hz ... 10 kHz
Limits 1... 50 %
Error ± 6 %
6. AC voltmeter
Range 0.02 ... 15 V
Frequency band 20 Hz ... 20 kHz
Error ± 6 %
7. Power meter
Level 0,2 ... 20 W (up to 50 W - w/ external attenuator FAD-2, up to 100 W - w/ FAD-3, by agreement with the Customer)   Note that when using the FAD type fix attenuators or analogs for measuring parameters of radio transmitter with the output power above 20 W, the power value measured by the device must be multiplied by the attenuation (fading) ratio of the attenuator by the formula Ratt=10 to the power of Ratt, dB/10)
Error < [10+(Pk/Pmst)] %

NVRAM can be used for storage of the test results.
The device can be supplied with a power source which provides not less than 4 hours offline
Also a solar cell battery can be used as a power supply.
Carrying case
Dimensions: 270 × 160 × 270 mm
