The National Instruments 788565-01, also known as the PXIe-5842 Vector Signal Transceiver (VST), is an advanced, compact solution that combines both a vector signal generator and a vector signal analyzer within a single four-slot PXI Express module. This versatile VST offers an extensive center frequency range, with options available up to 8 GHz, 12 GHz, 18 GHz, and 26.5 GHz, alongside a maximum equalized bandwidth of 2 GHz depending on the frequency range. Achieving high precision and rapid performance, the 788565-01 features a frequency tuning resolution of 8.89 µHz and a typical frequency settling time of 230 µs, ensuring a stable output signal. The module's design prioritizes phase settling capabilities for precise signal phase alignment, while its wide analog gain range effectively accommodates various signal strengths, a crucial feature in dynamic testing environments.

Supporting both internal and external pulse sources, the device maintains an on/off ratio that produces clean pulse transitions, enhanced by low pulse jitter and minimal rise/fall times. These attributes facilitate accurate pulse generation, making the PXIe-5842 particularly well-suited for applications in radar and communications. It features multiple pulse modulation modes, including digital and analog high isolation, to fulfill diverse application needs. Optimized for performance, the RF input phase noise is remarkably low, reaching -146 dBc/Hz at 10 MHz offset for 900 MHz signals, which helps to minimize signal distortion crucial for high-quality signal analysis in demanding applications, including 5G NR and Wi-Fi 7 testing. The 788565-01 is designed for robust use, operating effectively within a temperature range of 0 °C to 40 °C and tolerating humidity levels up to 90% noncondensing. Additionally, it withstands vibrations and shocks, making it a reliable choice for both laboratory and fieldwork. Overall, the 788565-01 presents a high-performance, efficient solution for contemporary RF testing and signal processing needs across a variety of industries, including semiconductor, aerospace, and defense.
