Keysight Technologies PNA and PNA-X network analysers

Click2Contact

Keysight Technologies’ enhanced PNA and PNA-X network analysers contain a proprietary low-spurious direct digital synthesis (DDS) source, enabling customers to take accurate measurements with less phase noise interference. With the clean source signals, customers can perform two-tone IMD measurements with close tone spacing previously only possible with high-performance analog signal generators.

The analysers’ DDS sources also enhance the performance of a wide range of software applications, including modulation distortion, SMC with phase and I/Q converter measurements. A third RF source of up to 13.5 GHz on the PNA-X simplifies measurement set-up by taking the place of an external signal generator to drive local oscillators.
