- Built-in system of self-testing and control of measurement accuracy, which displays an error message in the event that the measurement error of the instrument exceeds the permissible error in the passport;
- Ability to program by the user up to 99 values of the frequencies of the TV channels most often encountered in measurements;
- Possibility of storing up to 20 measurement results files (in 99 programs in each file) in the main memory of the device with indication of the measurement time;
- The presence of a serial interface for communication with the computer and transmission of measurement results stored in the device’s operative memory;
- Ability to display the amplitude-frequency characteristic of the trunk section by calculating the difference between any two recorded measurements;
- Mode of measuring the ratio of the image carrier and the sub carrier of sound;
- Mode of measuring the ratio of the image carrier and the noise level in the TV channel;
- Automatic and manual control of the input attenuator;
- Indication of thrunk-line supply voltage;
- Power supply from the built-in rechargeable battery or from an external adapter;
- Automatic charging of batteries when the device is operating from an external adapter;
- Indication of the discharge of the battery;
- Built-in loudspeaker for monitoring frequency-modulated signals and sound confirmation of pressing the buttons of the keyboard;
