Key Features

As modular instruments continue to grow rapidly in popularity, many test development engineers are realizing the advantages offered by the small, flexible form factor of PXI-based systems. As part of our commitment to offer products across multiple popular architectures, Signalcore offers the SC5305A, a three-stage superheterodyne downconverter for PXI Express that delivers superior image rejection over single stage conversion. The SC5305A has both high signal-to-noise dynamic range and high spurious free dynamic range. These products also exhibit very low phase noise of -110 dBc/Hz at 10 kHz offset on a 1 GHz RF carrier.

The excellent spurious free dynamic range is achieved using low noise linear amplifiers, low loss mixers, and high performance solid state attenuators. The final IF band response of the system is determined by surface acoustic wave (SAW) filtering. Frequency accuracy is provided by an onboard 10 MHz temperature compensated crystal oscillator (TCXO) which can be phase locked to an external reference source if required, and it is recommended to do so in applications that may require a more stable and accurate base reference.
