National Instruments 788565-01 Vector Signal Transceiver

The National Instruments 788565-01 (model name: PXIe-5842) is a versatile Vector Signal Transceiver (VST) that integrates both a vector signal generator and vector signal analyzer into a single, compact, four slot PXI Express module. This VST offers a wide center frequency range available in options up to 8 GHz, 12 GHz, 18 GHz and 26.5 GHz. The device's equalized bandwidth varies depending on the frequency range, with a maximum of 2 GHz.

The 788565-01 is designed with high precision and speed providing frequency tuning resolution down to 8.89 µHz and a fast frequency settling time of 230 µs typical for a stable signal output. The module also offers phase settling capabilities that ensure precise signal phase alignment. The device supports a wide analog gain range which varies with frequency and enables it to handle various signal strengths effectively. This feature is particularly beneficial in testing environments where signal conditions can vary significantly.

The NI 788565-01 supports both internal and external pulse sources with an on/off ratio that ensures clean pulse transitions. The pulse modulation capabilities are complemented by low pulse jitter and minimal rise/fall times. This ensures accurate and consistent pulse generation which is critical in radar, communications and similar applications. The VST also provides multiple pulse modulation modes that include digital and analog high isolation to meet different application requirements. The RF input phase noise performance of this VST is optimized across its frequency range with low phase noise down to -146 dBc/Hz at 10 MHz offset for 900 MHz signals. This ensures minimal signal distortion that is crucial for high quality signal analysis in demanding applications such as 5G NR and Wi-Fi 7 testing. The device also features robust RF input amplitude settling times that ensure quick adaptation to varying signal levels.

The 788565-01 module is engineered for demanding environments with operational temperature ranges from 0 °C to 40 °C and humidity tolerance up to 90% noncondensing. It is built to withstand operating vibrations and shocks that makes it reliable for both laboratory and field testing. This VST is an efficient, high performance solution for modern RF testing and signal processing needs across various industries, including semiconductor, aerospace and defense applications.
