PNA-X network analyzer

Agilent Technologies Inc. has launched the Option 028 to its PNA-X series of microwave network analyzers, allowing highly accurate, source-corrected noise figure measurements of amplifiers, frequency converters and mixers up to 50GHz.

The PNA-X, configured with Option 028, is the only network analyzer in the industry to correct for the effects of imperfect system source match. This is accomplished by using vector error correction to remove mismatch errors, and an ECal module as an impedance tuner to remove noise-parameter-induced errors. Such advanced calibration methods enable the PNA-X to offer what Agilent claims is the industry's highest noise-figure measurement accuracy, especially in on-wafer, in-fixture and automated-test environments.

Agilent's Option 028 uses the PNA-X's standard S-parameter receivers and Agilent's unique source-correction technique to make noise figure measurements up to 50GHz. For devices with less than 30dB of excess noise, an external preamplifier and filter are required.

For noise figure measurements up to 26.5GHz, an additional option (Option H29) is available that offers an internal low-noise receiver for 50GHz PNA-X instruments. Option H29 eliminates the need for an external preamplifier and filters, while making the setup as easy as that required for measuring S-parameters.

Model N5245A, two-port 50GHz PNA-X is priced at $140,000, while Option 028, source-corrected noise figure measurements using standard receivers for the 13.5-, 26.5-, 43.5- and 50GHz PNA-X models are at $24,000.
