SSG3000X Plus Series RF Signal Generator
New — now available from Pertech. The SSG3000X Plus is Siglent’s upgraded SSG3000X, with optimised hardware and software for a cleaner signal and better pulse fidelity, at the same price as the previous generation.
- Frequency range 9 kHz – 2.1 GHz / 3.2 GHz
- Level setting range: −110 dBm ~ +20 dBm (performance range up to +13 dBm)
- Phase Noise: −117 dBc/Hz @ 1 GHz, 20 kHz offset (typ.)
- Level accuracy ≤ 0.7 dB (typ.)
- Standard AM/FM/PM modulation and pulse modulation
- IQ modulation with 200 MHz RF bandwidth (‑IQE models)
- Pulse train generator (option)
Product Overview
The SIGLENT SSG3000X Plus series of RF signal generators covers 9 kHz to 2.1 GHz or 3.2 GHz. They provide standard AM, FM and PM analog modulation as well as pulse modulation and an optional pulse train generator. On the ‑IQE models, combine the generator with a baseband source such as the SIGLENT SDG6000X to produce IQ‑modulated signals such as QPSK and 16QAM, with EVM down to 0.7%.
Compared with the SSG3000X, the Plus generation brings a cleaner signal output and improved pulse fidelity, with wideband noise typically better than −153 dBc at a 40 MHz offset and a pulse on/off ratio of at least 68 dBc. A 5‑inch capacitive touch screen, USB power‑sensor support for closed‑loop level control, and web‑browser remote control make it equally suited to R&D benches, education labs and production test. An optional OCXO (10M_OCXO_L) tightens frequency stability to ±1 ppb.
