National Instruments 780413-01

The National Instruments 780413-01, also known as the PXIe-5663 RF Vector Signal Analyzer, is engineered for high-performance RF signal analysis across a frequency range of 10 MHz to 1.1 GHz. This versatile module enables wideband measurements with exceptional tuning resolution down to 533 nHz and supports an adjustable resolution bandwidth from under 1 Hz to 10 MHz, depending on the tuned frequency. Incorporating a stable internal frequency reference of 10 MHz, the analyzer exhibits strong temperature stability and aging accuracy, ensuring reliable long-term performance. It includes an external frequency reference input for enhanced synchronization with a rapid lock time.

Achieving impressive single sideband phase noise levels as low as -111 dBc/Hz at 100 MHz, the PXIe-5663 is capable of accurately measuring weak signals while minimizing interference. It features an amplitude range from the average noise level up to +30 dBm, with RF input attenuation adjustable in 1 dB increments from 0 dB to 50 dB. The module's architecture is specifically designed to reduce spurious responses, providing notable rejection levels for intermediate frequency and sideband spurs and ensuring minimal distortion in signal measurement. Low local oscillator (LO) leakage further enhances measurement accuracy.

The 780413-01 excels in linearity and delivers strong performance in third-order intermodulation distortion, with robust specifications for Error Vector Magnitude (EVM) and Modulation Error Ratio (MER). This makes it ideal for evaluating digital modulation quality across varying quadrature amplitude modulation (QAM) orders and carrier frequencies. The analyzer connects via SMA connectors for RF and IF signals and supports a maximum continuous RF power level of +30 dBm when RF attenuation is active. Additionally, it allows for advanced configurations with adjustable digital downconversion bandwidth. Compact in design, the module occupies a single PXI Express slot, with dimensions of 21.6 cm × 2.0 cm × 13.0 cm (8.5 in × 0.8 in × 5.1 in) and a weight of 1,245 g (43.9 oz). The product comes with a warranty ranging from 2 to 3 years, ensuring customer confidence in its reliability and performance.
