特性和优点

Ultra-low distortion, high-resolution source
- DC, 50Hz to 40kHz Frequency Range
- Proprietary digital pre-distortion (DPD) algorithm
- –130dBc THD @ 1kHz (typ.)
- Arbitrary waveform generation (AWG) with on-board pattern memory
- Differential (balanced) output up to 3.5VRMS
- Fast pattern switching between multiple stored waveforms
Fully Differential input Acquisition Channel
Small form-factor (60mm x 40mm)
Low power, 1W typ. (quiescent)
SPI interface for integration into test and measurement systems

产品详情

The ADMX1001 is an ultra-low distortion sinewave and high-resolution arbitrary waveform generator with an acquisition channel. This high-performance module demonstrates a proprietary digital pre-distortion algorithm that reduces signal distortion below levels that can be achieved with high-performance digital-to-analog converters (DAC) and amplifiers alone. Its differential output can be set to common-mode levels often required to test high-performance analog-to-digital converters (ADC), audio codecs, and other audio ICs and systems. The signal generator and the acquisition channel can be individually controlled using separate, easy to use, SPI interfaces - combined with the module's small-form factor, the ADMX1001 can be easily embedded into test systems, or simply used on the bench for measurement and characterization.

APPLICATIONS

High-end audio test
Analog-to-digital converter characterization and test
Sensor and transducer test
Frequency response and network analysis
ATE
