Rigol DG1022Z Function Generator
The Rigol DG1022Z is a robust, high-performance 25 MHz function and arbitrary waveform generator featuring 2 independent, fully functional channels and 14-bit vertical resolution. Driven by Rigol’s proprietary SiFi (Signal Fidelity) architecture, it delivers precise, point-by-point waveform generation with ultra-low jitter and a standard 2 Mpts memory depth, making it an essential bench tool for electronics education, R&D, and circuit validation.
Features & Benefits
-
25 MHz Output & 2 Independent Channels: Simultaneously generate two distinct signals or phase-locked outputs for complex dual-rail testing and circuit stimulation.
-
True 14-Bit Vertical Resolution: Provides 16,384 levels of amplitude precision, rendering smooth waveforms with minimal quantization noise.
-
SiFi (Signal Fidelity) Technology: Point-by-point arbitrary waveform generation guarantees 100% waveform replication and minimizes system jitter to 200 ps.
-
160 Built-In Arbitrary Waveforms: Instantly simulate complex real-world signals across engineering, medical, and mathematical applications without external software.
-
Built-in 7-Digit Frequency Counter: Accurately measures external signals up to 200 MHz, operating simultaneously with dual-channel output.
-
Comprehensive Modulation & Sweep: Full support for AM, FM, PM, ASK, FSK, PSK, and PWM, plus linear/logarithmic sweeping and burst modes.
Description
Redefining value in benchtop signal generation, the Rigol DG1022Z packs premium specifications into a reliable chassis. Unlike traditional DDS (Direct Digital Synthesis) generators that can suffer from phase jitter and edge distortion at varying frequencies, the DG1022Z utilizes advanced SiFi technology to reconstruct arbitrary waveforms point-by-point. This ensures exceptional signal fidelity and a remarkably low jitter of 200 ps, critical for testing sensitive analog and digital clock circuits.
