The National Instruments 782299-01, also known as the PXIe-5632, is a high-performance two-port vector network analyzer (VNA) designed specifically for PXI Express platforms. This advanced device is capable of conducting full S-parameter measurements over a broad frequency range of 300 kHz to 8.5 GHz, making it ideal for a diverse array of RF applications. The VNA features a dual source architecture with frequency offset capability, facilitating precise measurements on frequency translation devices and S-parameters. Enhanced by source access loops and low-latency triggers, the 782299-01 allows for efficient execution of pulsed S-parameter measurements and operates effectively across an extended power range.

Equipped with automatic precision calibration, this VNA ensures high accuracy and reliability, supporting various calibration methods including both automatic and manual options. It accommodates multiple calibration types such as 1-port SOL, 2-port SOLT, LRL (TRL), and LRM, effectively extending the reference plane for comprehensive vector analysis. The instrument's intermediate frequency (IF) bandwidth ranges from 10 Hz to 500 kHz, allowing users to adjust measurement speed and sensitivity per application requirements.

The PXIe-5632 boasts extensive sweep capabilities, supporting linear, segmented, and power sweeps with a frequency resolution of 1 Hz and a maximum sweep frequency up to 8.5 GHz. It can execute up to 20,001 measurement points per sweep, providing profound frequency analysis. Users benefit from various sweep modes, including single sweep, continuous sweep, and continuous wave (CW) modes, allowing flexibility in data collection and analysis. The VNA supports multiple data formats such as magnitude (both logarithmic and linear), phase, group delay, VSWR, impedance, and reflection/transmission coefficients, which are crucial for detailed examinations of RF components.

Source specifications for the 782299-01 include a leveled power range from -30 dBm to +15 dBm along with a power step resolution of 0.01 dB. The device features a dynamic range of up to 115 dB within the 1.5 GHz to 6 GHz frequency range, complemented by low trace noise and rapid measurement speeds, with typical measurement times varying from 15 ms to 7,302 ms based on span and number of points. The physical dimensions of the VNA are 21.6 cm x 6.0 cm x 13.0 cm (8.5 in x 2.4 in x 5.1 in), and it weighs 1,290 g (45.0 oz). The product is backed by a warranty period of 2 to 3 years, assuring users of its robust performance and reliability.
