As per Agilent Technologies, its PXA signal analyzer is the industry’s highest performance millimeter-wave signal analyzer. Covering frequencies up to 50 GHz, it extends to 325 GHz and beyond with external mixing. The instrument achieves an average noise level (DANL) of -138 dBm at 50 GHz and, using NFE, it improves DANL by about 6 dBm. Other features include a phase noise of -110 dBc/Hz at a 10-kHz offset, third-order intercept of +13 dBm at 50 GHz, support for M1970V/W waveguide harmonic mixers operating at frequencies up to 110 GHz, and support for third-party mixers. Prices for the N9030A PXA signal analyzer range from $51,900 for the 3.6-GHz option to $91,000 for the 50-GHz option. AGILENT TECHNOLOGIES INC., Santa Clara, CA. (877) 424-4536.
