SSG5000X Series
A high-purity analog and vector signal generator to 4 or 6 GHz with industry-leading phase noise, spectral purity and EVM. The -V models add an internal I/Q baseband generator for digitally-modulated and wideband vector signals — a true one-box source for 5G sub-6, Wi-Fi and radar work.
Analog & Vector Signal Generator
A high-purity analog and vector signal generator to 4 or 6 GHz with industry-leading phase noise, spectral purity and EVM. The -V models add an internal I/Q baseband generator for digitally-modulated and wideband vector signals — a true one-box source for 5G sub-6, Wi-Fi and radar work.
Every model shares the same platform, user interface and remote-control command set, so you choose purely on frequency and capability — and scale the analysis with licenses and accessories as your work grows. siglent.eu is the official EU distributor, with stock, warranty and local support.

Features in depth
Reference-grade signal purity
The SSG5000X targets the measurements where the source has to be cleaner than what you test — receiver blocking, ACPR and modulation quality.
- −120 dBc/Hz phase noise @ 1 GHz, 20 kHz offset
- Industry-leading spectral purity and low EVM
- Output up to +26 dBm with fine level control
- Pristine carrier for blocking, ACPR and intermod tests
Built-in vector engine (-V)
The -V models fold an I/Q baseband generator into the same box, so one instrument produces both clean carriers and modern digitally-modulated signals.
- Internal I/Q baseband — no external AWG needed
- Digitally-modulated & wideband vector signals
- IQ bandwidth upgradeable from 75 MHz to 150 MHz
- Ideal for 5G sub-6, Wi-Fi, Bluetooth and radar waveforms

10M-OCXO-L — high-accuracy OCXO clock source
An OCXO (Oven-Controlled Crystal Oscillator) is an internal hardware upgrade that replaces the SSG5000X’s standard 10 MHz reference with an oven-stabilised crystal. The result is a markedly more accurate and stable timebase — the foundation every frequency, level and modulation measurement is built on. Fit it when your application needs reference-grade frequency accuracy, low drift over temperature and time, or a common clock across the bench.
- Oven-stabilised crystal
The 10 MHz quartz crystal sits in a temperature-controlled oven, so the reference frequency barely moves as the lab warms up or cools down.
- Far tighter accuracy & ageing
Replaces the standard internal timebase with a much lower-drift reference — better initial accuracy and a smaller yearly ageing figure for reference-grade work.
- Cleaner close-in phase noise
A more stable timebase improves close-to-carrier phase noise and frequency stability, which matters for narrowband, EVM and modulation-quality measurements.
- Lock your whole bench
Provides a stable 10 MHz that other instruments can lock to (or be locked from) via the rear-panel reference, keeping a multi-instrument setup on one common clock.

Frequently asked questions
4 GHz (SSG5040X) or 6 GHz (SSG5060X); the 4 GHz models can be upgraded to 6 GHz with a license.
The -V models add an internal I/Q baseband generator, so they produce vector / digitally-modulated signals in one box. Non-V models are clean analog sources.
75 MHz, upgradeable to 150 MHz with the B150 license — wide enough for 5G sub-6, Wi-Fi and radar waveforms.
−120 dBc/Hz at 1 GHz, 20 kHz offset (typical) — among the best in its class.
Up to +26 dBm, with fine level control for both cabled and over-the-air setups.
