National Instruments 782550-01

The National Instruments 782550-01 IF Conditioning Module (PXIe-5694) is an advanced signal conditioning solution tailored for radio frequency (RF) applications. This PXI Express module supports both the downconversion and filtering of intermediate frequency (IF) signals, enhancing its versatility in various setups. Featuring five SMA connectors on the front panel and dual LED indicators, the 782550-01 ensures straightforward integration and real-time monitoring. The module offers multiple operational modes, including bypass, downconversion disabled, and downconversion enabled, each configured for specific input and output center frequencies. In bypass mode, the nominal center frequency is set at 187.5 MHz, while downconversion disabled mode operates at 193.6 MHz. The downconversion enabled mode outputs at a shifted frequency of 21.4 MHz, catering to applications that involve lower frequency signal processing.

Designed to refine signals effectively, the module integrates several bandpass filters with bandwidths ranging from 30 kHz to 160 MHz, significantly improving signal quality by removing unwanted frequencies. The module delivers exceptional performance with high rejection rates and low phase noise, achieving values as low as -155 dBc/Hz at a 1 MHz offset. It offers step gain adjustments for refined control over signal amplitude; the gain in bypass mode is typically around -1.5 dB, while in downconversion modes, it can range between 4.1 dB and 19.3 dB, enhancing the module’s linearity with high third-order intercept points.

The 782550-01 is designed to occupy a single PXI Express slot, with dimensions of 21.6 cm × 2.0 cm × 13.0 cm and a weight of 465 g. It operates within a temperature range of 0 °C to 55 °C and adheres to rigorous safety and electromagnetic compatibility standards. Its robust connectors and power requirements ensure optimal performance while safeguarding against voltage spikes and exceeding power handling. Ideal for demanding RF applications, the NI 782550-01 IF Conditioning Module offers a reliable and high-performance solution for signal processing needs.
