Features and benefits

Why I love FNIRSI 2D15P 3-in-1

Dual-Channel Output and High Sampling Rate: The FNIRSI TSG6020/TSG3020 boasts a dual-channel output with an impressive sampling rate of 200 MSa/s and a 14-bit vertical resolution. This ensures the generation of highly accurate and detailed waveforms, crucial for precise testing and analysis in complex electronic systems. The dual-channel capability allows for simultaneous generation of two independent signals, significantly enhancing efficiency in applications requiring multiple signal inputs or comparative analysis.
Extensive Waveform Generation and Frequency Range: These generators support a wide array of waveforms including Sine, Square, Ramp, Pulse, Noise, DC, and Arbitrary Waveforms. The TSG6020 offers a maximum output frequency of 60 MHz, while the TSG3020 reaches 30 MHz, with sine wave frequencies extending from 1 μHz up to 60 MHz (TSG6020) or 30 MHz (TSG3020). This broad frequency range and waveform variety make the devices suitable for diverse applications, from low-frequency sensor simulations to high-frequency RF testing.
Advanced Modulation and Sweep Functions: Equipped with six modulation types—AM, FM, PM, FSK, ASK, and PSK—the TSG series provides comprehensive signal manipulation capabilities. Users can define carrier and modulating waves from a selection of standard and arbitrary forms, with modulation frequencies up to 200 kHz for AM and PM, and 1 μHz – 200 kHz for FM. Additionally, the linear and logarithmic sweep modes, with sweep times from 1 ms to 500 s ± 0.1%, enable automated frequency response testing, simplifying characterization of filters, amplifiers, and other frequency-dependent circuits.
Integrated 7-Digit Frequency Counter and Precise Output Control: A built-in 7-digit frequency counter with a range of 100 mHz to 100 MHz and an accuracy of ±51 ppm allows for precise measurement of external signals, adding significant value as a standalone test instrument. The output characteristics are equally robust, offering an amplitude range of 1 mVpp to 10 Vpp (for ≤10 MHz, 50 Ω) or 1 mVpp to 5 Vpp (for ≤60 MHz, 50 Ω), with an accuracy of ±(5% of setting + 2 mVpp) for a 1 kHz sine wave. This level of precision ensures reliable and repeatable test results.
User-Friendly Interface and Robust Design: The 4.3-inch TFT capacitive touchscreen, combined with physical buttons, offers an intuitive and flexible control experience. The screen’s 90° adjustable angle enhances usability in various work environments. Power is supplied via a convenient Type-C 5V/2A interface, making it compatible with common power adapters and portable power banks. Furthermore, the device features channel protection and a typical output impedance of 50 Ω, ensuring durability and compatibility with standard test equipment.

Pros and Cons

Strengths & Weaknesses:

What I Like

Dual-channel output for simultaneous signal generation.
High sampling rate of 200 MSa/s and 14-bit vertical resolution for precise waveforms.
Wide range of standard and arbitrary waveforms (Sine, Square, Ramp, Pulse, Noise, DC, Arbitrary).
Comprehensive modulation capabilities (AM, FM, PM, FSK, ASK, PSK).
Built-in 7-digit frequency counter with 100 MHz range and good accuracy (±51 ppm).
Intuitive 4.3-inch TFT capacitive touchscreen with 90° adjustable angle.
Type-C 5V/2A power input for modern compatibility and portability.
Robust output characteristics including channel protection and 50 Ω impedance.

Points to Consider

Battery not included, limiting standalone portability without an external power source.
Max output amplitude decreases at higher frequencies (10 Vpp up to 10 MHz, 5 Vpp up to 60 MHz).
Frequency deviation values for FM modulation are not explicitly provided for the TSG series.
Information on software/firmware updates or advanced programming interfaces (beyond USB Device) is not explicitly detailed.
No explicit mention of internal storage capacity for arbitrary waveforms beyond «24 Waveforms».
