FNIRSI TSG3020 Function Generator

The FNIRSI TSG3020 combines accurate signal generation with intuitive operation for use in laboratories, workshops and in the field. Its dual-channel design, output frequency up to 60 MHz, 200 MSa/s sampling rate and 14-bit resolution produce high-quality signals with minimal distortion. It offers a selection of standard and arbitrary waveforms, six modulation types, a frequency sweep function and a built-in frequency counter. A touchscreen, signal-quality enhancement technologies and a robust design round out the instrument. Two independent channels: Generate two different signals simultaneously for more advanced measurements. The maximum output frequency is 60 MHz. The amplitude range depends on load and frequency. At high impedance, it is 2 mVpp to 20 Vpp below 10 MHz and 2 mVpp to 10 Vpp above 10 MHz. With a 50 Ω load, it is 1 mVpp to 10 Vpp below 10 MHz and 1 mVpp to 5 Vpp above 10 MHz. The 200 MSa/s sampling rate and 14-bit vertical resolution support accurate waveform reproduction, preserve fine details and keep distortion very low. Standard and arbitrary waveforms: Generate sine, square, ramp (sawtooth), pulse, noise and DC waveforms, as well as custom arbitrary waveforms created point by point for reproducing complex signals. VeriPoint technology supports arbitrary waveform sampling rates from 1 µSa/s to 200 MSa/s while maintaining signal detail and jitter below 200 ps. ZeroSurge technology improves square, pulse and sawtooth waveforms by limiting overshoot to a maximum of 1% and providing rise and fall times as short as 13.5 ns. This produces sharp edges and greater accuracy when testing electronic circuits. Advanced modulation: Six modulation types are supported: AM, FM, PM, FSK, ASK and PSK, for testing digital communication systems and radio equipment. Frequency sweeps can be linear or logarithmic, with sweep times adjustable from 1 ms to 500 s and accuracy of ±0.1%. These functions help analyse filter characteristics and the frequency response of equipment under test. The built-in 7-digit frequency counter supports TTL signals from 100 mHz to 100 MHz and measures frequency, period and duty cycle with an accuracy of ±51 ppm. Convenient operation: The generator provides an amplitude range of 1 mVpp to 10 Vpp with a 50 Ω load. Phase noise is no greater than -125 dBc/Hz at 10 MHz with a 10 kHz offset, and harmonic distortion is below -40 dBc in the 30 to 60 MHz range. Operation is controlled using a 4.3-inch colour TFT-LCD touchscreen and physical buttons for quick parameter changes. The display shows a waveform preview and the generator's current status to help configure and monitor settings. Configuration and protection: Output protection features include channel isolation, ground protection and a TTL-compatible synchronization output for safe, stable operation. An aluminium heat sink and quiet fan help maintain the operating temperature during extended use. Non-volatile memory stores up to 24 custom arbitrary waveforms for instant recall. The TSG3020 supports continuous operation, gated output, modulation and frequency sweep for flexible measurement setups and automated test systems.
