Precision You Can Trust
NABL-Accredited Calibration | Available on Request
The Rigol DSG3065B-IQ RF signal generator offers AM/FM/ØM analog modulation with a maximum frequency of 6.5 GHz. It comes with I/Q modulation and I/Q baseband output as a standard feature, ensuring high signal purity with phase noise measuring <-116 dBc/Hz at 20 kHz (typical). It is designed for precision with an output range of -130 dBm to +25 dBm, making it ideal for communication, R&D, and production environments..
✨ Why It Helps (Cause → Effect)
Clean carrier → fewer spurs → truer measurements.
Accurate level → repeatable tests → reliable results.
Wide range (9 kHz→6.5 GHz) → one box, many jobs → no gear swaps.
🎚️ Analog & Pulse Modulation
AM / FM / ØM (PM) built in → classic tests → quick checks on radios and IF chains.
Pulse modulation → crisp on/off keys → radar-like and burst tests stay honest.
Pulse train generation → timed packets on schedule → latency and timing studies made simple.
🧭 Advanced I/Q Capability
I/Q modulation + I/Q baseband → modern constellations on tap → realistic comms and SDR validation.
Custom mapping possible → real impairments modeled → receiver limits found faster.
🧪 Where It Fits (Use → Payoff)
Communications → standard waveforms → spec compliance with confidence.
R&D → fast setup → quicker iterate-test loops.
Production → stable outputs → consistent pass/fail gates.
🎯 High Signal Purity
Phase noise < −116 dBc/Hz @ 20 kHz (typ.) → cleaner carriers → tighter measurements.
Amplitude accuracy < 0.5 dB (typ.) → stable levels → repeatable results.
📡 Wide Frequency Range
9 kHz → 6.5 GHz with 0.01 Hz steps → audio to microwave in one box → no gear swap.
🧭 I/Q Modulation & Baseband
Built-in I/Q mod + I/Q baseband out → complex constellations on tap → realistic comms testing.
🎚️ Versatile Modulation
AM, FM, PM (ØM), Pulse → analog to digital styles covered.
Optional pulse train + custom pulse shapes → precise timing tests made simple.
🔌 Advanced Connectivity
USB / LAN / GPIB → drop into ATE → SCPI control and quick scripts.
USB storage → save/load setups → same signal every time.
🖥️ Compact, User-Friendly Design
4.3″ TFT LCD → clear menus, fast edits.
Manual trigger + presets + help key → quick starts, fewer mistakes.
