SSG3000X — 9 kHz to 3.2 GHz Analog RF Signal Generators
Analog RF signal generators for R&D, education and manufacturing, with 2.1 GHz and 3.2 GHz models. The series supports AM, FM, PM and pulse modulation as standard, optional pulse-train generation, USB/LAN remote control and IQE variants for external IQ modulation with a compatible baseband generator.

| SSG3021X-IQE | 9 kHz – 2.1 GHz | Yes — external IQ with baseband generator | −110 dBc/Hz typ. @ 1 GHz, 20 kHz offset | −110 dBm to +13 dBm |
| SSG3032X-IQE | 9 kHz – 3.2 GHz | Yes — external IQ with baseband generator | −110 dBc/Hz typ. @ 1 GHz, 20 kHz offset | −110 dBm to +13 dBm |
Key Features
2.1 GHz / 3.2 GHz RF Coverage
Model-dependent frequency coverage from 9 kHz up to 2.1 GHz or 3.2 GHz supports common RF receiver testing, LO injection, amplifier gain checks, RF education labs and production functional test.
AM / FM / PM / Pulse Modulation
Standard analog modulation modes support internal, external and combined source operation for receiver selectivity tests, modulation response checks and RF circuit validation.
IQE Variants for External IQ
SSG3000X-IQE models can generate IQ-modulated signals when used with a compatible external baseband source such as SIGLENT SDG6000X. Do not position the standard non-IQE models as vector generators.
Low Phase Noise Carrier
Typical phase noise of −110 dBc/Hz at 1 GHz and 20 kHz offset provides a clean CW or modulated RF source for receiver sensitivity, synthesizer and mixer measurements.
Pulse Train and USB Power Sensor Workflow
Optional pulse-train generation and USB power-meter correction workflows support pulsed RF tests, output-level verification and automated level-control use cases.
Touch UI and Remote Control
5-inch capacitive touch screen, USB Host, USB Device, LAN remote control and optional GPIB integration make the series suitable for bench and automated test setups.

Applications
Receiver Sensitivity and Selectivity
Calibrated RF output and modulation modes support receiver sensitivity, selectivity, blocking and demodulation checks in lab and production setups.
Amplifier Gain and Compression
CW and swept RF stimulus can be used for amplifier gain, gain flatness, compression and basic RF module characterisation.
Mixer and LO Injection
Low-phase-noise RF source for mixer conversion-loss tests, local oscillator injection and synthesizer chain verification.
RF Teaching Labs
Suitable for RF fundamentals, modulation demonstrations, spectrum-analyzer exercises and receiver-chain teaching labs.
RF Module Functional QC
SCPI and LAN/USB control allow repeatable RF stimulus generation for automated module production and incoming inspection.
External-IQ Modulated Signal Tests
IQE variants, combined with a compatible baseband generator, support external-IQ experiments such as two-tone and modulated-signal receiver checks.
