The SGA-60 from HAROGIC Technologies is a USB Vector Signal Generator that operates from 9 kHz to 6 GHz. It is designed to deliver laboratory-grade RF performance in a compact, cost-effective form factor for footprint-sensitive, budget-conscious test environments. This signal generator is based on a 16-bit DAC for high-quality baseband waveform synthesis and integrates an FPGA-based interpolator for fine-grained sampling-rate adjustment. It supports single-tone, frequency sweep, power sweep, IQ playback, and real-time IQ streaming, with a 100 MHz playback bandwidth. This signal generator has a real-time streaming bandwidth of 50 MHz, with a built-in memory depth of 125 MB (32 M samples).
The SGA-60 generates analog modulation signals (AM/FM), digital modulation signals including ASK, FSK, PSK, QAM up to 1024-QAM, APSK, DSSS, and OFDM, as well as pulse signals with configurable pulse repetition period, duty cycle, and pulse width. It provides output power ranging from less than -100 dBm to +14 dBm, with a power resolution of 0.1 dB. This signal generator has an SSB phase noise of -124 dBc/Hz (at 10 kHz offset), harmonic levels of less than -50 dBc and non-harmonic spurious of less than -55 dBc.
The SGA-60 supports internal or external reference clock inputs and integrates an optional built-in GNSS for timing, positioning, and frequency calibration, with 1PPS accuracy of ±100 ns. It can be controlled via a USB 3.0 Type-C interface and is compatible with Windows and Linux operating systems, supporting development environments for C/C++, C#, Python, MATLAB, LabVIEW, and GNU Radio. This signal generator requires a DC supply of 9 to 12 V and consumes less than 16 W. It is available as a compact module measuring 163 × 66 × 37 mm and has an N-type female RF output connector, an MMCX female reference clock input/output, and an SMA female GNSS antenna input. This signal generator is ideal for use in component characterization, digital modulation testing, radar signal simulation, receiver evaluation, and wireless communication R&D applications.
