NI arrived at European Microwave Week brandishing a new high-performance 26.5 GHz microwave vector signal analyser (VSA) and a fast tuning 20 GHz continuous wave signal generator. The two instruments combine to complement NI’s modular instruments offering and expand the measurement capabilities of the PXI platform.

The new instruments offer -166 dBm/Hz Noise floor and -129 dBc/Hz phase noise at 10Khz offset. This combination of low noise floor, high linearity, and low phase noise is allied to 765 MHz of instantaneous bandwidth. With the VSA’s bandwidth, engineers can analyse some of the industry’s widest bandwidth signals in a single acquisition including radar pulses, LTE-Advanced transmissions and 802.11ac waveforms.

In addition, the VSA’s fast measurement speed helps engineers decrease time to market and ultimately lower their cost of test.

Finally, engineers can program the VSA’s user-programmable FPGA with LabVIEW system design software to customise instrument behaviour and address the most advanced RF test applications.

The new 20 GHz signal generator features an excellent combination of exceptional phase noise and fast tuning time (100 µs). This instrument addresses applications including blocking/interferer generation, high-performance intermodulation distortion test benches and various electronic warfare applications.
