CRY5083 Analog Output - AOS
Product Highlights
4-Channel Synchronous Output for Multi-Point NVH Excitation
AOS provides four independent analog output channels with synchronous output capability, coordinated through the unified SonoDAQ platform time base. Compared with traditional single- or dual-channel excitation sources, the 4-channel synchronous architecture is better suited for multi-point excitation, active acoustic source arrays, bench control, and complex structural response testing.

Support for Differential, Single-Ended, and DC Output
The module supports differential, single-ended, and DC output modes. The single-ended output range is ±10 V, enabling compatibility with external power amplifiers, shaker controller inputs, actuator control interfaces, and standard voltage simulation interfaces. Output impedance is 20 Ω with a drive capability of 10 mA.

Multi-Waveform, Phase/Delay, and Playback Control
When used with OpenTest, AOS supports multi-waveform generation, phase control, delay control, and waveform playback. Users can define excitation signals centrally within the software and synchronize them with acquisition channels, providing stable excitation sources for FRF measurements, modal analysis, sweep testing, and repeatability testing.

High-Precision, Low-Noise Signal Output
AOS achieves amplitude accuracy of ±0.03 dB and frequency response flatness of ±0.01 dB from 20 Hz to 20 kHz. In the ±10 V range, the output noise floor is ≤ 10 µVrms, while THD is ≤ -100 dB at 1 kHz and 1 Vrms. Channel crosstalk is ≤ -110 dB @1 kHz, enabling stable and low-distortion analog excitation signal generation.

Comprehensive Protection and Mute Recovery Mechanisms
The module supports shutdown, short-circuit protection, overcurrent protection, overtemperature protection, and mute recovery functions. Fault status can be monitored, displayed, and logged within the software, helping engineers quickly identify abnormal conditions in the field and reduce the impact of wiring errors or abnormal loads on the test system.

Closed-Loop Test Platform with Input Modules
Together with input modules such as LMQ and IED, AOS forms a complete closed-loop workflow on the SonoDAQ + OpenTest platform, integrating excitation output, signal acquisition, real-time analysis, and report generation to improve overall system capability for NVH, acoustic, and structural testing.
