Rigol DSG821

Rs. 305148.00

The Rigol DSG821 RF signal generator offers standard AM/FM/ØM analog modulation with a maximum frequency of 2.1 GHz. It delivers high signal purity with phase noise of <-105 dBc/Hz @ 20 kHz (typical) and a wide output range from -110 dBm to +13 dBm. This generator also includes an optional pulse modulation capability with an on/off ratio of up to 70 dB. With USB-Host, USB-device, and LAN interfaces, it is ideal for communications, R&D, and production testing..

What it does
Generates clean RF signals → your tests stay clear → your results stay trusted.

Why it helps
AM/FM/ØM built in → one box, many tasks. Optional pulse mod → neat bursts, sharp edges.

Signal quality
Low phase noise → quieter carrier → fewer spurs → truer readings.

Power range
Wide output span → tiny levels for sensitive gear → strong levels for rugged rigs.

Where it fits
Comms, R&D, production, maintenance → one generator, many benches.

Plug & control
USB + LAN → quick setup → easy scripting → smooth integration.

Bottom line
DSG821 stays stable, stays precise → you dial a value → you get that value → tests run right.

✨ Standard Analog Modulation
AM, FM, and ØM built in → one box, many tests → less setup, faster results.

🎯 Pulse Modulation (Optional)
Add pulse mod → on/off depth to ~70 dB → clean bursts, crisp edges → custom pulse trains as you need.

🧼 High Signal Purity
Phase noise ~ −105 dBc/Hz @ 20 kHz (typ.) → quieter carrier → fewer spurs → truer measurements.

📶 Wide Output Range
−110 dBm to +13 dBm → tiny signals for sensitive receivers → strong signals for rugged rigs.

📏 Amplitude Accuracy
≈ ±0.5 dB (typ.) → levels stay honest → repeat tests match → trust your numbers.

🧩 Comprehensive Modulation Sources
Internal or external drive → AM/FM/ØM from inside the box or your analyzer → flexible setups, fewer cables.

🖱️ User-Friendly Interface
Clear screen + simple knobs → find settings fast → less menu diving, more testing.

🧳 Compact & Lightweight
Small body, low weight → benchtop stays tidy → field work feels easy.
