Modulation Distortion Up To 70 GHz
S930707B
-
S930707B enables fast and accurate active-device modulation distortion characterization under modulated stimulus condition up to 70 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. S930707B 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.
