SDG2000X — 80–120 MHz AWG with 16-bit DAC and IQ Output
Advanced dual-channel AWG — 16-bit DAC, 1.2 GSa/s, IQ modulation output and wideband noise generation for RF testing, ADC characterisation and complex signal simulation.
| Model | Max Frequency | DAC | Sample Rate | IQ Output |
|---|---|---|---|---|
| SDG2082X | 80 MHz | 16-bit | 1.2 GSa/s | Yes |
| SDG2122X | 120 MHz | 16-bit | 1.2 GSa/s | Yes |
Key Features
16-bit DAC — 65,536 Amplitude Levels
Four times the resolution of 14-bit generators. Lower harmonic distortion and improved SFDR for precision RF carrier simulation and ADC characterisation.
IQ Modulation Output
Map Ch1 to I and Ch2 to Q for complex baseband signal generation — simulate OFDM, QAM and custom modulation for RF transceiver validation.
Wideband Noise Generation
Bandlimited Gaussian noise with programmable bandwidth and amplitude for noise immunity testing and ADC noise floor measurement.
1.2 GSa/s — Deep Arbitrary Waveforms
1.2 GSa/s with large arb memory enables complex long-sequence signal playback for serial data patterns and radar chirp sequences.
