    Selective signal level analyzer SA-104

    Categories: Analogue broadcasting, Measuring equipment Tags: analyzer, level, radio signals, SA-104
    • Description

    Functionality:

    • Display of all measured parameters and service information in digital form on the LCD;
    • Additional indication of the signal level within the units of dB (0-9dB) by a graphic linear indicator simulating a dial gauge;
    • The ability to directly dial from the keyboard frequency, TV channel number or program;
    • Automatic measurement of signal level without entering correction factors;
    • Built-in self-test and accuracy control system;
    • Possibility to program up to 80 frequency values of the TV channels most often met by the user;
    • Availability of a range scan mode for detecting signals and interference with the possibility of the user to set the detection threshold;
    • The function of detecting the deviation of the level of the monitored signal from the nominal value, with the possibility of programming deviation tolerance;
    • The ability to quickly switch to the mode of measuring the sub-carrier level of the TV signal sound (5.5MHz, 6.5MHz);
    • 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;
    • Measurement of mains supply voltage;
    • Power supply of the device from the built-in storage battery or from AC adapter 220V / 50Hz;
    • Automatic charging of batteries when working from an AC adapter;
    • Built-in loudspeaker for monitoring frequency-modulated signals and sound confirmation of pressing the buttons of the keyboard;
    • Tuning the volume level and forcing the speaker to turn off;
    • Possibility of storing up to 3 measurement results files in the main memory of the device (80 programs in each file);
    • The presence of a serial interface for communication with the computer and transmission of measurement results stored in the device’s operative memory;
    • Automatic switch-off of the device in a supply mode from the storage battery, with an opportunity of programming by the user of time of an auto power-off;
    • The software is supplied with the device as a graphic editor Cable Test 1, which allows the user to store the measurement results in a convenient way.
    • LCD backlight;
    • Tuning the contrast of the display.
