The National Instruments 778283-01 RF Signal Downconverter, also known as the PXI-5600 module, is a compact 3U PXI solution designed for a wide array of RF analysis applications. This downconverter operates across a frequency range of 9 kHz to 2.7 GHz, offering an impressive real-time bandwidth of 20 MHz and maintaining exceptional stability for precise measurements. With a frequency stability of ±20 parts per billion (ppb) and accuracy of ±50 ppb, the 778283-01 ensures reliable performance even under varying temperature conditions, making it suitable for demanding automation tasks where frequency precision is crucial.

The module features adjustable input attenuation of 50 dB in 10 dB steps, accommodating full-scale input signals from +30 dBm down to less than -130 dBm. Its performance metrics include over 80 dB of intermodulation spurious-free dynamic range and a typical noise floor of less than -140 dBm/Hz, with phase noise of less than -94 dBc/Hz at a 10 kHz offset. The 778283-01 seamlessly integrates with PXI digitizers for comprehensive RF analysis and enhances the measurement capabilities with available toolkits for modulation and spectrum analysis.

Additionally, this downconverter facilitates synchronization with other PXI modules, such as digital multimeters, audio analyzers, and machine vision equipment, through extensive trigger capabilities via the PXI trigger bus, PXI star trigger line, or front panel SMA connector. By utilizing one intermediate frequency (IF) output channel and one RF input channel, the 778283-01 elevates RF analysis with vector measurements and robust integration, positioning it as a versatile asset for engineers in the field of RF testing and analysis.
