Precision You Can Trust
NABL-Accredited Calibration | Available on Request
The Rigol DSG821A RF signal generator provides standard AM/FM/ØM analog modulation with a maximum frequency of 2.1 GHz. It includes I/Q modulation, offering high signal purity with phase noise measuring <-105 dBc/Hz @ 20 kHz (typical). The generator features a wide output range from -110 dBm to +13 dBm and is equipped with USB-Host, USB-device, and LAN interfaces for connectivity. This compact and lightweight signal generator is ideal for RF testing in communications, R&D, and production environments..
✨ What It Does
Generates precise RF signals → your tests stay clear → your readings stay trusted.
🧠 Modulation Options
AM/FM/ØM built in → one box, many signals.
I/Q included → complex waveforms → closer-to-real radios.
🧼 Signal Quality
Low phase noise (≈ −105 dBc/Hz @ 20 kHz, typ.) → quiet carrier → cleaner measurements.
📶 Output Range
−110 dBm to +13 dBm → tiny levels for sensitive gear → strong levels for rugged rigs.
🎯 Accuracy & Stability
Amplitude ≈ ±0.5 dB (typ.) → levels stay honest → repeat tests match.
Stable PLL → frequency stays put → results stay consistent.
🧩 Where It Fits
R&D benches, comms labs, classrooms, production lines → one generator → many jobs.
🔌 Easy Integration
USB + LAN → quick control, simple scripts → smooth fit in racks and test code.
🖱️ User Experience
Clear UI + straightforward knobs → find settings fast → test sooner, tweak less.
🧳 Form Factor
Compact and light → tidy benches → easy field carry.
✨ Standard Analog Modulation
AM/FM/ØM built in → one box, many signals → faster test setup.
🧠 I/Q Modulation
I/Q included → flexible wave shapes → closer-to-real radios.
🧼 High Signal Purity
Phase noise ~ −105 dBc/Hz @ 20 kHz (typ.) → quiet carrier → cleaner measurements.
📶 Wide Output Range
−110 dBm to +13 dBm → tiny levels for sensitive gear → strong levels for rugged rigs.
📏 Amplitude Accuracy
≈ ±0.5 dB (typ.) → levels stay honest → repeat tests match.
🎯 Optional Pulse Modulation
Add pulse mod → on/off depth to ~70 dB → sharp bursts on demand → make custom pulse trains.
🧩 Modulation Sources
Internal or external drive → AM/FM/ØM from inside the box or your source → simpler wiring, more choice.
🖱️ User-Friendly Interface
Clear screen + intuitive controls → find settings fast → test sooner, tweak less.
🧳 Compact & Lightweight
Small, portable body → easy on the bench → easy in the field.
