FNIRSI TSG3020 2-Channel Function Signal Generator

The FNIRSI TSG3020 is a two-channel function signal generator with an output frequency of up to 60 MHz, designed for laboratories, workshops and fieldwork. Its two independent channels allow two different signals to be generated at the same time, which supports more advanced measurements. A 200 MSa/s sampling rate and 14-bit vertical resolution reproduce waveforms accurately with very low distortion.

Besides common standard waveforms such as sine, square, ramp, pulse, noise and DC, the generator can build arbitrary waveforms point by point. It supports six modulation types (AM, FM, PM, FSK, ASK and PSK) and a frequency sweep function with linear or logarithmic timing. A built-in 7-digit frequency counter adds further measuring capability.

Operation is handled by a 4.3-inch colour TFT touchscreen supplemented by physical buttons, with a waveform preview and device status shown on the display. Non-volatile memory stores up to 24 custom waveforms, while channel isolation and an aluminium heatsink with a quiet fan support continuous use. The package includes the generator, charger adapter, Type-C charging cable, data cable, test leads, crocodile clips and a user manual.
