Modulation Distortion Up To 43.5 GHz
S930704B
-
S930704B enables fast and accurate active-device modulation distortion characterization under modulated stimulus condition up to 43.5 GHz. The wide dynamic range and vector error correction of the PNA-X result in an extremely low residual EVM of the test setup, so you can get a complete picture of your device’s performance without test system interference. S930704B can measure EVM, NPR, ACPR, and can decompose nonlinear signals and linear signals with the spectral correlation between input and output spectrum without doing demodulation. Integration with the PNA-X SCCM provides quick modulation distortion measurements while making other VNA measurements.

These waveguide bandwidth harmonic mixers are designed for use with spectrum analzyers with diplexers, such as the Tektronix 492 and 494 and the Hewlett-Packard 8555A, 8565A and 8569A. They are also used as phase locking and receiver mixers for antenna measurement systems such as the Scientific Atlanta wide range receivers. When used with an external diplexer*, these harmonicmixers can be used to phase lock millimeter wave sources.
