Function Generator FNIRSI TSG6020

Precise signal generation, extensive configuration options and advanced measurement functions make the FNIRSI TSG6020 ideal for use in laboratories, as well as for service work and electronic circuit design. Its dual-channel design, output frequency up to 60 mHz and sampling rate of 200 MSa/ss with 14-bit resolution ensure accurate waveform reproduction and high operational accuracy. The generator supports many types of modulation, allows you to create your own arbitrary waveforms and offers a frequency scan function and a built-in frequency counter. The intuitive touch screen, quick access to saved settings and robust design ensure that the device is easy to use even during intensive, long-term operation.

High quality generated signals

The FNIRSI TSG6020 is equipped with two independent output channels, which allows the simultaneous generation of two different signals and the convenient implementation of more advanced tests and analyses. The generator offers an output frequency of up to 60 mHz, and thanks to the 200 MSa/s sampling rate and 14-bit vertical resolution, it ensures very accurate reproduction of waveforms with minimal distortion. The output voltage range is optimized for various load configurations - from 2 mVpp to 20 Vpp at high impedance for frequencies below 10 mHz, from 2 mVpp to 10 Vpp above 10 mHz, as well as from 1 mVpp to 10 Vpp and from 1 mVpp to 5 Vpp at a 50 Ω load. This flexibility allows the device to be used in a variety of demanding laboratory and design applications.

Standard waveforms and advanced modulations

The generator supports all commonly used waveforms such as sine, square, sawtooth, pulse, noise and DC. In addition to the predefined waveforms, it allows you to reproduce your own arbitrary waveforms using the point-by-point method, ensuring that all the details of the waveform are preserved. VeriPoint technology uses a sampling rate of 1 µSa/s to 200 MSa/s and very low jitter below 200 ps, ensuring accurate reproduction of even the most complex signal shapes. The device also supports six types of modulation (AM, FM, PM, FSK, ASK and PSK), making it ideal for testing digital communication circuits and radio systems.

Even greater accuracy

ZeroSurge technology significantly reduces overshoot on square, pulse and sawtooth signals. Overshoot does not exceed 1%, and rise and fall times are a maximum of 13.5 ns, resulting in sharp edges and very high accuracy of the generated waveforms. The generator is also equipped with a seven-digit frequency counter that measures the frequency, period and duty cycle of TTL-level signals in the range from 100 mHz to 100 mHz with an accuracy of ±51 ppm. The high signal quality is also confirmed by parameters such as low phase noise of up to -125 dBc/Hz at 10 mHz (10 kHz offset) and harmonic distortion below -40 dBc in the range from 30 to 60 mHz.

Frequency sweeping and user-friendly operation

The FNIRSI TSG6020 offers frequency modulation in linear and logarithmic modes. The modulation time can be set from 1 ms to 500 s with an accuracy of ±0.1%, which allows, among other things, the analysis of filter characteristics and testing the response of various electronic circuits. Operation is simplified by a 4.3-inch color TFT-LCD touch screen that works in conjunction with traditional physical buttons. The screen shows a preview of the generated waveform and key operating parameters in real time, allowing you to quickly check the settings and make any necessary adjustments.

Stable performance even during long-term tests

The generator is designed for reliable operation during intensive use. Efficient heat dissipation is provided by an aluminum heat sink supported by a quiet fan that maintains proper component temperatures even during hours of operation. The design also includes output channel protection, isolation and ground protection, while a TTL-compatible sync output improves integration options with other measurement devices. Non-volatile memory allows the storage of up to 24 custom waveforms that can be instantly recalled without the need for reconfiguration. The generator also supports multiple operating modes, including continuous, gated, modulation and shift modes, providing great flexibility in setting up even complex test benches.
