✨ 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.
