The RF Explorer Signal Generator COMBO is a compact, professional-grade RF signal generator covering a continuous frequency range from 100 kHz to 6 GHz with no gaps — making it one of the most capable pocket-sized signal generators available. An upgraded evolution of the standard RFE6GEN, the COMBO integrates high-performance amplifiers and advanced harmonic filtering for superior signal purity. At 25 MHz, the COMBO produces a clean sinusoidal CW output compared to the more squared waveform of the unfiltered RFE6GEN — a clear advantage for precision RF testing, filter evaluation, and demanding measurement applications. Precise amplitude control in 0.25 dB steps up to +18 dBm, a solid aluminium housing for RF shielding, and a high-capacity Li-Po battery with 10+ hours runtime make it equally at home in the lab, on the bench, or in the field. Free PC software supports CW, sweep, and tracking generator modes, with Python and .NET automation support via a free USB API.
