National Instruments 781219-01 2-Port Vector Network Analyzer
The National Instruments 781219-01 is a compact and versatile 2 port Vector Network Analyzer (VNA) designed for PXI Express systems. The model is also known as the PXIe-5630. This VNA is equipped to perform vector measurements of transmission (S21) and reflection (S11) coefficients across a broad frequency range of 10 MHz to 6 GHz. The model is ideal for automated design validation and production testing due to its wide dynamic range, high measurement accuracy and rapid sweep speeds.
The 781219-01 model frequency accuracy is maintained at ±2.5 ppm that is augmented by internal or external timebase aging and temperature stability mechanisms. The internal timebase ensures reliable operation with an aging rate of ±1 ppm and temperature stability of ±2.5 ppm/°C. The module offers a power range of +5 dBm to -30 dBm along with an accuracy of ±2 dB at 5 dBm test port power and ±4 dB at any test port power. This power range and accuracy are crucial for accurate signal characterization. The power step resolution of 0.5 dB further adds to its flexibility that allows users to finely adjust the signal power for various measurement needs.
The receiver characteristics of this Vector Network Analyzer are optimized for low noise and high dynamic range. The noise floor ranges from <-115 dBm/Hz at frequencies below 3 GHz to <-110 dBm/Hz at frequencies up to 6 GHz. The dynamic range of the analyzer exceeds 100 dB across its frequency range that ensures that even weak signals can be detected and accurately measured. The model has physical dimensions of 21.6 cm × 4.0 cm × 13.0 cm and weighs 680 kilograms.
The 781219-01 analyzer also boasts rapid measurement speeds along with the ability to handle various spans and intermediate frequency bandwidths (IFBW) efficiently. In zero span mode with a 30 kHz IFBW, the module can complete a sweep in as little as 28 ms. This speed is particularly advantageous in high throughput testing environments where time efficiency is critical. The model offers corrected system performance with precision calibration kits that ensure directivity, source match, and load match specifications are maintained across its frequency range.
