This paper discusses the setup details for the demo shown in this video Head to Head: NI 5665 vs. Traditional Boxed Instruments. The demo compares the performance and speed of the NI PXIe-5665 with the Agilent PXA. Rather than comparing the datasheet specifications of both instruments, this video compares the two instruments while performing real- world test scenarios.

Hardware Setup

For the LTE and WCDMA test, the NI PXIe-5673 vector signal generator is used. The filter is used for only the WCDMA signal to improve the dynamic range of the signal as much as possible. For the linearity test, two CW sources are used to generate tones that are combined using a combiner from Mini-Circuits. All signals are split to the NI PXIe-5665 VSA and the Agilent PXA. Figure 1. Hardware Setup and Connectivity This setup ensures that the same signal is reaching the NI PXIe-5665 and the Agilent PXA at the same time.
